Area Code 821

Area code 821 is one of the newest NANP area codes

Area code 821 is one of the most recently added codes in the North American Numbering Plan, in service since August 19, 2024. It is an overlay that shares its territory with 864, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 821 number.

Because 821 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 821?” An area code only shows where a number is registered, and any number can be spoofed — so a 821 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 821 a scam?

Is a call from area code 821 a scam?

A 821 number is geographically tied to South Carolina, 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 821 a country code?

No. 821 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 821 number written for international dialing looks like +1 821 followed by the 7-digit local number.
