Area code lookup

One box for the North American numbering plan: an area code, a full number, or a state or province name, answered from a dated bundled dataset in this tab.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

Report a problem

Type an area code, paste a phone number, or name a state or province. The answer appears as you type.

Dated data, inferred zones

The list is a curated snapshot dated 2026-10-01 (NANPA area code reports and CNAC Canadian maps, hand-transcribed). Time zones are inferred from region boundaries, so a code that straddles a zone line is listed with every zone it touches and may not match a specific carrier. Codes assigned after the snapshot answer as not found rather than guessed.

Search

Presets

Digits resolve to the area code (10 digits, or 11 with a leading 1); anything else is matched as a state, province, or country name. All 397 codes live in this page, so nothing is sent anywhere.
