Area Code Lookup by ExpressNumber

Type a US area code or paste a phone number to see the state, main cities, the time there now and if it is a good time to call.

Area Code Lookup answers two questions: where is this area code, and is it a good time to call there? Click the toolbar icon, type a three-digit US area code or paste a whole phone number, and the answer is there. What you see for each area code: - The state or territory it belongs to. - The main cities it covers. - The time there right now, read from your browser's own time zone data. Codes that cover two time zones show both clocks. - Whether it is a sensible hour to call. 8:00 AM to 8:59 PM there counts as a good time, and the popup tells you when it is a bit early, a bit late or the middle of the night. - Other area codes laid over the same area, one click away. It reads phone numbers in any format: +1 (212) 555-0100, 212.555.0100 or 2125550100. Arizona is shown on its own clock, because most of the state does not change its clocks for daylight saving. Toll-free codes, special service codes, Canadian and Caribbean codes, and codes that are not in use get a plain one-line answer. The popup remembers your last five lookups and your 12-hour or 24-hour choice on your own computer. Nothing is sent anywhere: the extension makes no network requests and asks for one browser permission, storage. There is no account. Area Code Lookup is made by ExpressNumber.
