Area Code by ZIP Code

Our Area Code by ZIP Code product is ideal for Webmasters and Fraud Detection Specialists who need to validate whether the Area Code a user enters corresponds with their ZIP Code. This is a one-to-many relationship where all ZIP Code to Area Code combinations are included. This unique Area Code by ZIP Code database includes area code splits and overlays*.

area code by zip code This Area Code Database product is updated quarterly. The price includes an initial download and all updates to our ZIP Code to Area Code product made available throughout your subscription period.

*An Area Code Overlay is an alternate Area Code that applies to the same area as another Area Code. Overlays were created so that an area code would not have to be split again. For instance, Miami has 305 for their main area code, but 786 is a valid, alternate area code within the same geographic area.
