Got a missed call from 909?

Our directory lists 909 for Anaheim, California, but an area code alone cannot establish who is calling. Scammers can fake caller ID to match the first six digits of the number they are dialing, a trick called neighbor spoofing, so a familiar-looking code proves nothing about who is really calling.

If you were not expecting the call, let it go to voicemail. Verify the caller through a trusted contact method before returning the call, and never share personal details with an unverified caller.

Worth knowing: an area code no longer tells you where someone is. Mobile numbers keep their original code when people move, so a 909 number may belong to someone who left California years ago.

Frequently asked questions about 909

Where is area code 909?

Our directory lists area code 909 for Anaheim, California. The listed city is a reference location, not a complete coverage map. A phone number's area code does not establish the caller's current location.

What time zone is area code 909 in?

This directory uses Pacific Time (PT) for California. This is state-level guidance; confirm the recipient's local time before calling.

Is area code 909 a scam?

An area code alone cannot tell you whether a call is genuine. Caller ID can be spoofed, including numbers that appear local. Let unexpected calls go to voicemail and verify the caller independently before sharing personal information.

Is area code 909 toll-free?

The directory lists 909 as a geographic area code, not a toll-free code. US toll-free codes include 800, 833, 844, 855, 866, 877, and 888. Your carrier and calling plan determine any charges.

History of Area Code 909

Area code 909 began service on November 14, 1992, when it split from area code 714. At the time, 714 covered a much larger part of Southern California. The new code added numbering capacity as the region’s population and demand for telephone lines grew.

Area code 951 split from 909 on July 17, 2004, creating a separate area code for communities including Riverside. On June 23, 2021, area code 840 began overlaying the 909 region. An overlay adds a second area code to the same geographic area, allowing existing 909 customers to keep their numbers while new numbers may use 840.
