What is the most semantic way to display a street address in HTML?

Questions:

I have an address that is going to be displayed on a webpage, but it is not the address for the author of the page. How should this be coded to be semantic given the w3c recommendation of:

The ADDRESS element may be used by authors to supply contact information for a document or a major part of a document such as a form. This element often appears at the beginning or end of a document.

Answers:

You could use the hCard Microformat to describe your address. The advantage of Microformats is that you can use them in your existing documents to enrich them.

Here’s an example derived from the example from the Microformats wiki:

<address class="vcard">
  <span class="adr">
    <span class="street-address">169 University Avenue</span>
    <span class="locality">Palo Alto</span>,  
    <abbr class="region" title="California">CA</abbr>&nbsp;&nbsp;
    <span class="postal-code">94301</span>
    <span class="country-name">USA</span>
  </span>
</address>

The answer by Gumbo is missing the vital ingredient. An hcard/vcard is required to have a name.

Also the address tag should not be used in this case as it is specifically used to relate to the author of the page it is displayed on.

<div class="vcard">
  <span class="fn">Tristan Ginger</span>
  <span class="adr">
    <span class="street-address">169 University Avenue</span>
    <span class="locality">Palo Alto</span>,  
    <abbr class="region" title="California">CA</abbr>
    <span class="postal-code">94301</span>
    <span class="country-name">USA</span>
  </span>
</div>

Most business wanting to display their address on their website should use the following:

<address class="vcard">
  <span class="fn org">Tristan Ginger Inc</span>
  <span class="adr">
    <span class="street-address">69 University Avenue</span>
    <span class="locality">Great Bookham</span>,  
    <span class="region">Surrey</span>
    <span class="postal-code">KT22 9TQ</span>
    <span class="country-name">UK</span>
  </span>
</address>

you can use RDFa, eg:

<html
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:foaf="http://xmlns.com/foaf/0.1/"
    xmlns:address="http://schemas.talis.com/2005/address/schema#"
    xml:lang="fr" lang="fr"
>
 <head>...</head>
 <body>
  <div typeof="foaf:Person" about="http://you.openid.com#me">
   <span id="name" property="foaf:name">First Name, Last Name</span>
   <address property="address:streetAddress">My Street, My City</address>
  </div>
 </body>
</html>

You can use the Schema.org vocabulary’s PostalAddress item for this. It can be used via Microdata, RDFa, or JSON-LD.

For example, using RDFa:

<div vocab="http://schema.org/" typeof="PostalAddress">
 <span property="name">Google Inc.</span>
 P.O. Box<span property="postOfficeBoxNumber">1234</span>
 <span property="addressLocality">Mountain View</span>,
 <span property="addressRegion">CA</span>
 <span property="postalCode">94043</span>
 <span property="addressCountry">United States</span>
</div>

AFAIK, this should also be valid with <address> in place of the enclosing <div>:

<address vocab="http://schema.org/" typeof="PostalAddress">
 <span property="name">Google Inc.</span>
 P.O. Box<span property="postOfficeBoxNumber">1234</span>
 <span property="addressLocality">Mountain View</span>,
 <span property="addressRegion">CA</span>
 <span property="postalCode">94043</span>
 <span property="addressCountry">United States</span>
</address>
