Area Code by ZIP Code

All ZIP Code to Area Code Combinations Included

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*.

*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.
