ISO Standard Street Addresses?

No; each country defines its own standard.

There have been a number of questions about this in times past, including:

• Best practices for storing postal addresses in an RDBMS
• Is there a common street address database design for all addresses of the world

The second of those itself has references to a number of other SO questions.

You might want to check out the grandiosely named Universal Postal Union and its standards.

There are none. However, you can also consider that place is usually contained in a bigger place.

So, you can also use the hierarchical structure of places in following an address format. Which also means it differs from country-to-country.

You can read stuffs about this on:

• Universal Postal Union's paper Addressing the world, an address for everyone
• Place ontology from schema.org
• PostalAddress ontology from schema.org.
