<entry-title>h-adr</entry-title> Tantek Çelik (Editor)

h-adr is a simple, open format for publishing postal address information on the web. h-adr is one of several open microformat draft standards suitable for embedding data in HTML/HTML5.

h-adr is the microformats2 replacement for adr. It is most commonly used as part of an h-card or h-event.


Here is a simple minimal person example:

<p class="p-adr h-adr">
  <span class="p-street-address">17 Austerstræti</span>
  <span class="p-locality">Reykjavík</span>
  <span class="p-country-name">Iceland</span>
  <span class="p-postal-code">107</span>

Get started

The class h-adr is a root class name that indicates the presence of an h-adr.

p-street-address, p-extended-address and all the other h-adr property classnames define an element as a property of the h-adr.

See microformats2 parsing specification to learn more about property classnames.


  • p-street-address - house/apartment number, floor, street name
  • p-extended-address - additional street details
  • p-post-office-box
  • p-locality - city/town/village
  • p-region - state/county/province
  • p-postal-code - postal code, e.g. ZIP in the US
  • p-country-name - country name
  • p-label - new in vCard4 (RFC6350)
  • p-geo (or u-geo with a RFC 5870 geo: URL), optionally a nested h-geo
  • p-latitude - metric latitude
  • p-longitude - metric longitude
  • p-altitude - metric altitude

For backward compatibility, you may wish to use classic adr classnames in addition to the more future-proof h-adr properties, for example:

<span class="p-street-address street-address">123 Main St.</span>

Microformats parsers should detect classic properties and parse them as microformats 2 properties. If an "h-adr" is found, don't look for an "adr" on the same element.

Compatibility root class name: adr

Properties: (parsed as p- plain text unless otherwise specified)

  • post-office-box
  • extended-address
  • street-address
  • locality
  • region
  • postal-code
  • country-name


h-adr is a microformats.org draft specification. Public discussion on h-adr takes place on h-adr-feedback, the #microformats #microformats chat channel on irc.freenode.net, and microformats-new mailing list.

h-adr is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-adrs up with classic adr classnames.

Examples in the Wild

  • … add any h-adr examples you find in the wild


h-adr is based on the existing adr specification, which was extracted from hCard 1.0 in order to allow it to be used for applications other than contact information.
