  <t>
    This document defines the vCard data format for representing and exchanging
    a variety of information about individuals and other entities (e.g.,
    formatted and structured name and delivery addresses, email address,
    multiple telephone numbers, photograph, logo, audio clips, etc.).
  </t>

<section title="Introduction">
  <t>Electronic address books have become ubiquitous. Their increased presence
    on portable, connected devices as well as the diversity of platforms
    exchanging contact data call for a standard. This memo defines the vCard
    format, which allows the capture and exchange of information normally stored
    within an address book or directory
    application.</t>
</section>

<section title="Conventions" anchor="oldsection_Abstract">
  <t>The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
    "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document
    are to be interpreted as described in <xref target="RFC2119"/>.</t>
</section>

<section title="vCard Format Specification">

  <t>The text/vcard MIME content type (hereafter known as "vCard", see <xref
      target="mime_type_registration"/>) contains
    contact information, typically pertaining to a single contact or group of
    contacts.  The content consists of one or more lines in the format given
    below.</t>

  <section title="Line Delimiting and Folding" anchor="folding">

    <t>Individual lines within vCard are delimited by the <xref
        target="RFC5322"/> line break, which is a CRLF sequence (ASCII decimal
      13, followed by ASCII decimal 10). Long logical lines of text can be split
      into a multiple-physical-line representation using the following folding
      technique. Content lines SHOULD be folded to a maximum width of 75 octets.
      Multi-octet characters MUST remain contiguous. The rationale for this
      folding process can be found in <xref target="RFC5322"/>, Section
      2.1.1.</t>

    <t>A logical line MAY be continued on the next physical line anywhere
      between two characters by inserting a CRLF immediately followed by a
      single white space character (space, ASCII decimal 32, or horizontal tab,
      ASCII decimal 9). The folded line MUST contain at least one character. Any
      sequence of CRLF followed immediately by a single white space character is
      ignored (removed) when processing the content type.  For example the
      line:</t>
    <figure><artwork>
  DESCRIPTION:This is a long description that exists on a long line.
    </artwork></figure>
    <figure>
      <preamble>can be represented as:</preamble>
      <artwork>
  DESCRIPTION:This is a long description
    that exists on a long line.
      </artwork>
    </figure>
    <figure>
      <preamble>It could also be represented as:</preamble>
      <artwork>
  DESCRIPTION:This is a long descrip
   tion that exists o
   n a long line.
      </artwork>
    </figure>

    <t>The process of moving from this folded multiple-line representation of a
      property definition to its single line representation is called unfolding.
      Unfolding is accomplished by regarding CRLF immediately followed by a
      white space character (namely HTAB ASCII decimal 9 or SPACE ASCII decimal
      32) as equivalent to no characters at all (i.e., the CRLF and single white
      space character are removed).
      <list>
        <t>Note: It is possible for very simple implementations to generate
          improperly folded lines in the middle of a UTF-8 multi-octet sequence.
          For this reason, implementations SHOULD unfold lines in such a way as
          to properly restore the original sequence.</t>
        <t>Note: Unfolding is done differently than in <xref target="RFC5322"/>.
          Unfolding in <xref target="RFC5322"/> only removes the CRLF, not the
          space following it.</t>
      </list>
    </t>


    <t>Folding is done after any content encoding of a type value. Unfolding is
      done before any decoding of a type value in a content line.</t>

  </section>

  <section title="ABNF Format Definition">

    <t>The following ABNF uses the notation of <xref target="RFC5234"/>, which
      also defines CRLF, WSP, DQUOTE, VCHAR, ALPHA, and DIGIT.</t>

    <figure>
      <artwork>
  vcard-entity = 1*(vcard)

  vcard = "BEGIN" ":" "VCARD" CRLF
          1*contentline
          "END" ":" "VCARD" CRLF
    ;A vCard object MUST include the VERSION and FN properties.

  contentline = [group "."] name *(";" param) ":" value CRLF
    ; When parsing a content line, folded lines must first
    ; be unfolded according to the unfolding procedure
    ; described above.
    ; When generating a content line, lines longer than 75
    ; characters SHOULD be folded according to the folding
    ; procedure described above.

  group = 1*(ALPHA / DIGIT / "-")
  name  = "SOURCE" / "NAME" / "KIND" / "FN" / "N" / "NICKNAME"
        / "PHOTO" / "BDAY" / "DDAY" / "BIRTH" / "DEATH" / "SEX"
        / "ADR" / "LABEL" / "TEL" / "EMAIL" / "IMPP" / "LANG"
        / "TZ" / "GEO" / "TITLE" / "ROLE" / "LOGO" / "ORG" / "MEMBER"
        / "RELATED" / "CATEGORIES" / "NOTE" / "PRODID" / "REV"
        / "SORT-STRING" / "SOUND" / "UID" / "CLIENTPIDMAP" / "URL"
        / "VERSION" / "CLASS" / "KEY" / "FBURL" / "CALADRURI"
        / "CALURI" / "XML" / iana-token / x-name
    ; Parsing of the param and value is based on the "name" as
    ; defined in ABNF sections below.
    ; Group and name are case-insensitive.

  iana-token = 1*(ALPHA / DIGIT / "-")
    ; identifier registered with IANA

  x-name = "x-" 1*(ALPHA / DIGIT / "-")
    ; Names that begin with "x-" or "X-" are
    ; reserved for experimental use, not intended for released
    ; products, or for use in bilateral agreements.

  param = language-param / encoding-param / value-param / pref-param
        / pid-param / type-param / geo-param / tz-param / any-param
    ; Allowed parameters depend on property name.

  param-value = *SAFE-CHAR / DQUOTE *QSAFE-CHAR DQUOTE

  any-param  = (iana-token / x-name) "=" param-value

  NON-ASCII = %x80-FF
    ; Use is restricted by UTF-8

  QSAFE-CHAR = WSP / %x21 / %x23-7E / NON-ASCII
    ; Any character except CTLs, DQUOTE

  SAFE-CHAR = WSP / %x21 / %x23-39 / %x3C-7E / NON-ASCII
    ; Any character except CTLs, DQUOTE, ";", ":"

  VALUE-CHAR = WSP / VCHAR / NON-ASCII
    ; Any textual character
      </artwork>
    </figure>

    <t>A line that begins with a white space character is a continuation of the
      previous line, as described above. The white space character and
      immediately preceeding CRLF should be discarded when reconstructing the
      original line. Note that this line-folding convention differs from that
      found in <xref target="RFC5322"/>, in that the sequence
      <CRLF><WSP> found anywhere in the content indicates a
      continued line and should be removed.</t>

    <t>Property names and parameter names are case insensitive (e.g., the
      property name "fn" is the same as "FN" and "Fn"). Parameter values MAY be
      case sensitive or case insensitive, depending on their definition.</t>

    <t>The group construct is used to group related properties together. The
      group name is a syntactic convention used to indicate that all property
      names prefaced with the same group name SHOULD be grouped together when
      displayed by an application. It has no other significance.
      Implementations that do not understand or support grouping MAY simply
      strip off any text before a "." to the left of the type name and present
      the types and values as normal.</t>

    <t>Properties defined in a vCard instance may have multiple values depending
      on the property cardinality. The general rule for encoding multi-valued
      properties is to simply create a new content line for each value
      (including the property name).  However, it should be noted that some
      value types support encoding multiple values in a single content line by
      separating the values with a comma ",".  This approach has been taken for
      several of the content types defined below (date, time, integer, float),
      for space-saving reasons.</t>

  </section>

  <section title="Property Value Escaping">
    <t>Some properties may contain one or more values delimited by a COMMA
      character (ASCII decimal 44). Therefore, a COMMA character in a value MUST
      be escaped with a BACKSLASH character (ASCII decimal 92), even for
      properties that don't allow multiple instances (for consistency).</t>

    <t>Some properties (e.g. N and ADR) comprise multiple fields delimited by a
      SEMI-COLON character (ASCII decimal 59). Therefore, a SEMI-COLON in a
      field of such a "compound" property MUST be escaped with a BACKSLASH
      character. SEMI-COLON characters in non-compound properties MUST NOT be
      escaped.</t>

    <t>Furthermore, some fields of compound properties may contain a list of
      values delimited by a COMMA character. Therefore, a COMMA character in one
      of a field's values MUST be escaped with a BACKSLASH character, even for
      fields that don't allow multiple values (for consistency). Compound
      properties allowing multiple instances MUST NOT be encoded in a single
      content line.</t>

    <t>Finally, BACKSLASH characters in values MUST be escaped with a BACKSLASH
      character. NEWLINE (ASCII decimal 10) characters in values MUST be encoded
      by two characters: a BACKSLASH followed by an 'n' (ASCII decimal 110).</t>

    <t>In all other cases, escaping MUST NOT be used.</t>
  </section>

  <section title="Character Set">
    <t>The character set for vCard is UTF-8 as defined in <xref
        target="RFC3629"/>. There is no way to override this.</t>

  <section title="ENCODING" anchor="ENCODING">
    <t>The "encoding" property parameter is used to specify an alternate
      encoding for a value.  If the value contains a CRLF, it must be encoded,
      since CRLF is used to separate lines in the content-type itself.
      Currently, only the "b" encoding is supported.</t>

    <t>The "b" encoding can also be useful for binary values that are mixed with
      other text information in the body part (e.g., a certificate).  Using a
      per-value "b" encoding in this case leaves the other information in a more
      readable form. The encoded base 64 value can be split across multiple
      physical lines by using the line folding technique described above.</t>

    <t>The Content-Transfer-Encoding header field is used to specify the
      encoding used for the body part as a whole. The "encoding" property
      parameter is used to specify an encoding for a particular value (e.g., a
      certificate).  In this case, the Content-Transfer-Encoding header might
      specify "8bit", while the one certificate value might specify an encoding
      of "b" via an "encoding=b" property parameter.</t>

    <t>The Content-Transfer-Encoding and the encodings of individual properties
      given by the "encoding" property parameter are independent of one another.
      When encoding a text/vcard body part for transmission, individual
      property encodings are performed first, then the entire body part is
      encoded according to the Content-Transfer-Encoding.  When decoding a
      text/vcard body part, the Content-Transfer-Encoding is decoded first,
      and then any individual properties with an "encoding" property parameter
      are decoded.</t>

  </section>

  <section title="VALUE" anchor="VALUE">
    <t>The "value" parameter is optional, and is used to identify the value type
      (data type) and format of the value.  The use of these predefined formats
      is encouraged even if the value parameter is not explicitly used.  By
      defining a standard set of value types and their formats, existing parsing
      and processing code can be leveraged. The predefined data type values MUST
      NOT be repeated in COMMA separated value lists except within the N,
      NICKNAME, ADR and CATEGORIES properties.</t>

    <t>Including the value type explicitly as part of each property provides an
      extra hint to keep parsing simple and support more generalized
      applications.  For example a search engine would not have to know the
      particular value types for all of the items for which it is searching.
      Because the value type is explicit in the definition, the search engine
      could look for dates in any item type and provide results that can still
      be interpreted.</t>

  <section title="PREF" anchor="PREF">
    <t>The "pref" parameter is optional, and is used to indicate that the
      corresponding instance of a property is preferred by the vCard author. Its
      value MUST be an integer between 1 and 100 that quantifies the level of
      preference. Lower values correspond to a higher level of
      preference, 1 being most preferred.</t>
    <t>When the parameter is absent, the default MUST be to interpret the
      property instance as being least preferred.</t>
    <t>Note that the value of this parameter is to be interpreted only in

      same vCard. A given value, or the absence of a value, MUST NOT be

      appear more than once in a given property. It MUST NOT appear on
      properties that only may have one instance per vCard.  Its value is either
      a single small integer, or a pair of small integers separated by a dot.
      Multiple values may be encoded in a single PID parameter by separating the
      values with a comma ",". See <xref target="synchronization"/> for more
      details on its usage.</t>

  <section title="TYPE" anchor="TYPE">
    <t>The "type" parameter has multiple, different uses. In general, it is a
      way of specifying class characteristics of the associated property. Most
      of the time, its value is a comma-separated subset of a pre-defined
      enumeration. In this document, the following properties make use of this
      parameter: FN, NICKNAME, PHOTO, ADR, LABEL, TEL, EMAIL, IMPP, LANG, TZ,
      GEO, TITLE, ROLE, LOGO, ORG, RELATED, CATEGORIES, NOTE, SOUND, URL, KEY,
      FIBURL, CALADRURI, and CALURI. The TYPE parameter MUST NOT be
      applied on other properties defined in this document.</t>
    <t>The "work" and "home" values can be used wherever the TYPE parameter is
      allowed, but only when the KIND property is absent or its value is
      "individual". They act like tags. The "work" value implies that the
      property is related to an individual's work place, while the "home" value
      implies that the property is related to an individual's personal life.
      When neither "work" nor "home" is present, it is implied that the property
      is related to both an individual's work place and personal life in case
      the KIND property's value is "individual", or to none in other cases.</t>

<section title="Synchronization" anchor="synchronization">

  <t>vCard data often needs to be synchronized between devices. In this context,
    synchronization is defined as the intelligent merging of two representations
    of the same object. vCard 4.0 includes mechanisms to aid this process.</t>

  <section title="Mechanisms">

    <t>Two mechanisms are available: the UID property is used to match
      multiple instances of the same vCard, while the PID parameter is used to
      match multiple instances of the same property.</t>

    <t>The term "matching" is used here to mean recognizing that two instances
      are in fact representations of the same object. For example, a single
      vCard that is shared with someone results in two vCard instances. After
      they have evolved separately, they still represent the same object, and
      therefore may be matched by a synchronization engine.</t>

    <section title="Matching vCard Instances">
      <t>vCard instances for which the UID properties (<xref target="UID"/>) are
        equivalent MUST be matched. Equivalence is determined as specified in
        <xref target="RFC3986"/>, Section 6.</t>

      <t>In all other cases, vCard instances MAY be matched at the discretion of
        the synchronization engine.</t>
    </section>

    <section title="Matching Property Instances" anchor="propmatching">
      <t>Property instances belonging to unmatched vCards MUST NOT be
        matched.</t>

      <t>Property instances whose name (e.g. EMAIL, TEL, etc.) is not the same
        MUST NOT be matched.</t>

      <t>Property instances whose name is CLIENTPIDMAP are handled separately
        and MUST NOT be matched. The synchronization MUST ensure that there is
        consistency of CLIENTPIDMAPs among matched vCard instances.</t>

      <t>Property instances belonging to matched vCards, whose name is the same,
        and whose maximum cardinality is 1 MUST be matched.</t>

      <t>Property instances belonging to matched vCards, whose name is the same,
        and whose PID parameters match MUST be matched. See <xref
          target="pidmatching"/> for details on PID matching.</t>

      <t>In all other cases, property instances MAY be matched at the discretion
        of the synchronization engine.</t>
    </section>

    <section title="PID Matching" anchor="pidmatching">
      <t>Two PID values for which the first fields are equivalent represent the
        same local value.</t>

      <t>Two PID values representing the same local value and for which the
        second fields point to CLIENTPIDMAP properties whose second field URIs
        are equivalent (as specified in <xref target="RFC3986"/>, Section 6)
        also represent the same global value.</t>

      <t>PID parameters for which at least one pair of their values represent
        the same global value MUST be matched.</t>

      <t>The FN properties are matched automatically because their maximum
        cardinality is 1. Since the property value is the same, no update takes

      <t>On the first device, the same PID source identifier (1) is reused for
        the new EMAIL and TEL properties. On the second device, a new source
        identifier (2) is generated, and a corresponding CLIENTPIDMAP property
        is created. It contains the second device's identifier,
        "urn:uuid:1f762d2b-03c4-4a83-9a03-75ff658a6eee".</t>
      <t>The new EMAIL properties are unmatched on both sides since the PID global
        value is new in both cases. The sync thus results in a copy on both
        sides.</t>
      <t>Although the situation appears to be the same for the TEL properties,
        in this case the synchronization engine is particularly smart and
        matches the two new TEL properties even though their PID global values
        are different. Note that in this case, the rules of section <xref
          target="propmatching"/> state that two properties may be matched at
        the discretion of the synchronization engine. Therefore, the two
        properties are merged.</t>
      <t>All this results in the following vCard which is stored on both
        devices:</t>

    <list style="symbols">
      <t>Internet mail is often used to transport vCards and is subject to many
        well known security attacks, including monitoring, replay, and forgery.
        Care should be taken by any directory service in allowing information to
        leave the scope of the service itself, where any access controls can no
        longer be guaranteed.  Applications should also take care to display
        directory data in a "safe" environment (e.g., PostScript-valued
        types).</t> <t>vCards can carry cryptographic keys or certificates, as
        described
        in <xref target="KEY"/>.</t>
      <t><xref target="CLASS"/> specifies a desired security
        classification policy for a particular vCard. That policy is not
        enforced in any way.</t>
      <t>The vCard objects have no inherent authentication or privacy, but
        can easily be carried by any security mechanism that transfers MIME
        objects with authentication or privacy. In cases where the threat of
        "spoofed" vCard information is a concern, the vCard SHOULD BE
        transported using one of these secure mechanisms.</t>
      <t>The information in a vCard may become out of date. In cases where
        the vitality of data is important to an originator of a vCard, the
        "URL" type described in <xref target="URL"/> SHOULD BE
        specified. In addition, the "REV" type described in section <xref
          target="REV"/> can be specified to indicate the last
        time that the vCard data was updated.</t>

  <section title="Registering New vCard Elements" anchor="iana_registration">

    <t>This section defines the process for registering new or modified vCard
      elements (i.e. properties, parameters, value data types, and values) with
      IANA.</t>

    <section title="Registration Procedure">
      <t>The IETF will create a mailing list,
        <eref target="mailto:vcard@ietf.org">vcard@ietf.org</eref>, which can
        be used for public discussion of vCard element proposals prior to
        registration.  Use of the mailing list is strongly encouraged.  The IESG
        will appoint a designated expert who will monitor the
        <eref target="mailto:vcard@ietf.org">vcard@ietf.org</eref> mailing list
        and review registrations.</t>

      <t>Registration of new vCard elements MUST be reviewed by the
        designated expert and published in an RFC.  A Standard Tracks RFC is
        REQUIRED for the registration of new value data types that modify
        existing properties.  A Standard Tracks RFC is also REQUIRED for
        registration of vCard elements that modify vCard elements previously
        documented in a Standard Tracks RFC.</t>

      <t>The registration procedure begins when a completed registration
        template, defined in the sections below, is sent to
        <eref target="mailto:vcard@ietf.org">vcard@ietf.org</eref> and
        <eref target="mailto:iana@iana.org">iana@iana.org</eref>.  The
        designated expert is expected to tell IANA and the submitter of the
        registration within two weeks whether the registration is approved,
        approved with minor changes, or rejected with cause.  When a
        registration is rejected with cause, it can be re-submitted if the
        concerns listed in the cause are addressed.  Decisions made by the
        designated expert can be appealed to the IESG Applications Area
        Director, then to the IESG.  They follow the normal appeals procedure
        for IESG decisions.</t>

      <t>Once the registration procedure concludes successfully, IANA creates or
        modifies the corresponding record in the vCard registry. The completed
        registration template is discarded.</t>
    </section>

    <section title="Vendor Namespace">

      <t>The vendor namespace is used for vCard elements associated with
        commercially available products.  "Vendor" or "producer" are construed
        as equivalent and very broadly in this context.</t>

      <t>A registration may be placed in the vendor namespace by anyone who
        needs to interchange files associated with the particular product.
        However, the registration formally belongs to the vendor or organization
        handling the vCard elements in the namespace being registered.  Changes
        to the specification will be made at their request, as discussed in
        subsequent sections.</t>

      <t>vCard elements belonging to the vendor namespace will be distinguished
        by the "VND-" prefix.  This is followed by an IANA-registered Private
        Enterprise Number (PEN), a dash, and a vCard element designation of the
        vendor's choosing (e.g., "VND-123456-MUDPIE").</t>

      <t>While public exposure and review of vCard elements to be registered in
        the vendor namespace is not required, using the <eref
          target="mailto:vcard@ietf.org">vcard@ietf.org</eref> mailing list for
        review is strongly encouraged to improve the quality of those
        specifications.  Registrations in the vendor namespace may be submitted
        directly to the IANA.</t>

  <section title="Differences from RFCs 2425 and 2426" anchor="diff">
    <t>
      This appendix contains a list of changes that have been made in the vCard
      specification from RFCs 2425 and 2426.
    </t>

    <section title="New Structure">
      <t>
        <list style="symbols">
          <t><xref target="RFC2425"/> and <xref target="RFC2426"/> have been
            merged. Initially <xref target="RFC2425"/> was intended to
            be extensible but only 2426 ever extended it.</t>
          <t>vCard is now not only a MIME type but a stand-alone format.</t>
          <t>A proper MIME type registration form has been included.</t>
          <t>UTF-8 is now the default character set.</t>
          <t>New vCard elements can be registered from IANA.</t>
          <t>Changed "manager" to "supervisor".</t>
          <t>Added "family", "supervisee", and "colleague" RELATED types.</t>
        </list>
      </t>
    </section>

    <section title="Removed Features">
      <t>
        <list style="symbols">
          <t>The group construct (i.e. GROUP.PROPERTY:...) no longer exists.</t>
          <t>The CONTEXT and CHARSET parameters are no more.</t>
          <t>The MAILER property is no more.</t>
          <t>The "intl", "dom", "postal", and "parcel" TYPE parameter values for
            the ADR and LABEL properties have been removed.</t>
          <t>Inline vCards (such as the value of the AGENT property) are no
            longer supported.</t>
          <t>In the N property, additional names are now subsumed into the given
            names list.</t>
        </list>
      </t>
    </section>

    <section title="New Properties and Parameters">
      <t>
        <list style="symbols">
          <t>The KIND, SEX, LANG, DDAY, BIRTH, and DEATH properties
            have been added.</t>
          <t><xref target="RFC2739"/>, which defines the FBURL, CALADRURI,
              CAPURI, and CALURI properties, has been merged in.</t>
          <t><xref target="RFC4770"/>, which defines the IMPP property, has been
            merged in.</t>
          <t>The "work", "home", and "uri" TYPE parameter values for the EMAIL
            property have been added.</t>
          <t>The "pref" value of the TYPE parameter is now a parameter of its
            own, with a positive integer value indicating the level of
