US area codes by state

How to use the area code directory

The area code groups organize listed US codes by their first digit. Each series is a browsing aid, not a single geographic region. Its entries can belong to different states and time zones. Start with the full three-digit area code, then open its individual page for the listed locality and regional context.

Use the search field to narrow the directory by city or area code. If you know the state but not the code, open the state heading to compare its complete directory. A state may use several codes, including overlays that cover the same area. The city beside a code is a reference point; it is not a complete list of every community it serves.

An area code describes a numbering area, not a caller’s current location or identity. People can keep a number after moving, and caller ID can be spoofed. Compare an unexpected call with other evidence before replying. Do not treat a familiar prefix as proof that a caller represents a local business or public agency.

This directory lists geographic US entries from our area-code inventory. A missing number is not proof that it is invalid or unassigned. For allocation details, consult the source references on the individual code page. To inspect another first-digit range, choose a group above or clear the group selection to see all US area codes.
