About Zip Area Code

Zip Area Code is an independent lookup site for US ZIP codes and area codes. Every town, county and state has a page with its ZIP codes and post offices, its area codes and overlays, its time zone and the towns around it, and every area code has a page with its NANPA facts, a map and the places it serves.

Where the data comes from

• GeoNames: Town and place names, with their coordinates. GeoNames data is shared under the Creative Commons Attribution 4.0 license. (CC BY 4.0)
• U.S. Census Bureau: ZIP code areas (ZCTAs), places and counties, and the shapes the area code maps are drawn from.
• NANPA: The North American Numbering Plan Administrator: each area code, its overlays, its date in service, its local dialing plan and its time zones.

The area codes of each ZIP code are matched from telephone rate centers: each ZIP code area takes the codes of the rate centers that serve it. A ZIP code on a boundary can have numbers from either side, and a ZIP code with no mapped area of its own, such as one for P.O. boxes, takes the codes of the nearest ZIP code area. Why ZIP codes and area codes don't line up

The local numbers listed here

Town, county, state and area code pages also list local phone numbers for sale. Each listing links to the seller, Exclusive Digits, which confirms at checkout that the number has not already gone to someone else.

An earlier site at this address

This web address was home to a different ZIP code and area code site from about 2009 to 2013. Zip Area Code was built in 2026 and has no tie to that site beyond the address. The earlier site's town, county, state, area code and ZIP code addresses still work: each leads to the matching page here.
