Yes, there are several custom tags that you could probably use to do this. Or you
could download the zip codes database from the UPSP and build something yourself.
You're looking for the "Tiger/Zip" database which is updated each month by the USPS.
If the USPS site wasn't so slow, I'd give you a link to the database.
You can read about the Tiger/Zip database here:
http://www.tpsnet.com/html/tigerzip-specs.html
You don't HAVE to buy this database from anyone although you might find it more
convenient to do so.
