710 area code — NANP area non-geographic

Data: NANPA public reports, current as of July 28, 2026.

710 is the area code assigned to NANP area, in service since January 1, 1984, Eastern time. Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

710 is reserved for US Government use and is not available for public assignment. It carries no geographic territory, no rate centers and no public prefix records. Calls displaying a 710 number outside federal contexts warrant scepticism: legitimate agency outreach to the public does not originate from this code, and the safe response to any unexpected "government" call is to hang up and use the agency's published contact channels.

If a 710 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.

FAQ

Why am I getting spam calls from 710 numbers?

Scammers spoof real area codes so calls look legitimate. A displayed 710 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 710 number from?

710 is assigned to NANP area in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
