Pasadena, CA Area Code

Area code serving Pasadena

Pasadena sits in California, part of the West region and the Pacific Time zone. Its area code is 626, which covers San Gabriel Valley of Los Angeles County, including Pasadena, El Monte and West Covina. 626 has no overlay today, so every Pasadena landline and mobile number with a local code starts with 626.

626 has served the area since 1997. If the region runs low on numbers, regulators will most likely add an overlay code on top rather than split the area, which would make 10-digit dialing mandatory.

Getting a Pasadena phone number

Any new landline, mobile or VoIP number from a local carrier in Pasadena gets the 626 area code. Numbers come from the blocks each carrier holds in the area; a number ported in from elsewhere keeps its original area code, so you may also see out-of-state codes locally.

Dialing in Pasadena

Pasadena is covered by the single area code 626 with no overlay, so some local calls may still connect with seven digits. Dialing all 10 digits (area code + seven-digit number) always works and is the safest habit. From outside the US, dial +1, then the area code and number. See 10-digit dialing and overlay area codes for the background. For every code in California, visit the California area codes page.
