About MetroZipCodes

We bridge the gap between USPS Zip Codes and OMB Metropolitan Statistical Areas (MSAs). Our data helps businesses, marketers, and researchers understand the true economic footprint of a region beyond city limits.

What is an MSA?

An MSA is a core urban area of at least 50,000 people, plus adjacent counties with high economic integration.

Example: The City of Atlanta has roughly 500,000 people, but the Atlanta MSA has over 6 million.
