Area Code 983

Area code 983 is one of the newest NANP area codes

Area code 983 is one of the most recently added codes in the North American Numbering Plan, in service since June 17, 2022. It is an overlay that shares its territory with 303, 720, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 983 number.

Because 983 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 983?” An area code only shows where a number is registered, and any number can be spoofed — so a 983 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 983 a scam?

Is a call from area code 983 a scam?

A 983 number is geographically tied to Colorado, but caller ID can be spoofed, so the displayed area code does not prove where a caller really is. If you did not expect the call, do not share personal information and consider looking the number up.

Is 983 a country code?

No. 983 is a US area code (a domestic 3-digit code), not a country code. The country (calling) code for the United States is +1, shared across the North American Numbering Plan. So a full 983 number written for international dialing looks like +1 983 followed by the 7-digit local number.
