Phone numbers beginning 209 are registered to the Stockton area of California (Pacific time zone). The code entered service on January 1, 1958. Together with 350 it forms the 209/350 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 209, assigned to 46 carriers. 605 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 63 rate centers (billing localities).
Practical takeaway: the 209 label narrows geography to California, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.
Its parent code is 415, which it left in 1958. Later relief produced 559 (1998), 350 (2022) from its territory.
Official projections put exhaust for the 209/350 complex at 1Q 2056.

FAQ
Why am I getting spam calls from 209 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 209 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 209 number from?
209 is assigned to Stockton 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 209 a toll-free number?
No. 209 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 350 and 209 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 209/350 complex shares one service area, and local calls are dialed with 10 digits.
