626 Area Code: Pasadena, California

The 626 area code covers the San Gabriel Valley east of downtown Los Angeles, with Pasadena as its primary city. Pasadena sits at the foot of the San Gabriel Mountains, where the foothills give way to the floor of the valley, and its older neighborhoods are organized around a downtown grid that retains a substantial cluster of pre-war buildings. The city is home to the California Institute of Technology, the Jet Propulsion Laboratory, and the Rose Bowl, and its working economy reflects all three — a research-and-engineering core layered onto a broader civic infrastructure that serves the eastern half of the LA metro.

A long list of California cities — Anaheim, Bakersfield, Chico, Concord, and others — appears in the directory's records tied to 626 numbers. None are inside the 626 footprint. Their appearance reflects the standard California pattern: high number mobility, porting, address linkage across cities, and public-record cross-referencing that pays no attention to area-code lines. We currently track 547 distinct prefixes within 626 in detail, a working subset of the active prefix population.

Pasadena's home values come in dramatically above the US median — typical valuations run roughly three to four times the national reading, reflecting the San Gabriel Valley's enduring pricing pressure. Median household income sits well above the US figure, the city's median age skews a touch older than the country, and population places Pasadena as a substantial mid-sized city within the broader Los Angeles region.
