The 707 area code covers Santa Rosa, California, Pacific time zone, and dates back to January 1, 1959. Together with 369 it forms the 369/707 overlay. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.

NANPA lists 784 active NXX prefixes in 707, assigned to 36 carriers. 616 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 75 rate centers (billing localities).

Official projections put exhaust for the 369/707 complex at 2Q 2070.

The dialing plan is 1+10D for home-NPA local calls and 1+10D across codes.

If a 707 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.

Its parent code is 415, which it left in 1959. Later relief produced 369 (2023) from its territory.

FAQ

Will 707 run out of numbers?

NANPA's current forecast projects exhaust in 2Q 2070 — decades of capacity remain.

Why am I getting spam calls from 707 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 707 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 707 number from?

707 is assigned to Santa Rosa and surrounding areas of California in the Pacific time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 707 a toll-free number?

No. 707 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
