213 Area Code: Los Angeles, California

The 213 code is the original area code of Los Angeles and remains tightly associated with the city's downtown and inner core. As a numbering-plan designation, 213 has been carrying numbers in this part of California since the earliest decades of direct-distance dialing, and it sits inside what is now a complex overlay of codes that cover the broader Los Angeles basin. Downtown Los Angeles itself — the historic civic core, the theater district, financial blocks, and the expanding warehouse-conversion neighborhoods to the south and east — anchors the 213 footprint.

Records in the directory associated with 213 numbers often reference other California cities — Anaheim, Bakersfield, Chico, Concord, and many more. None of those fall inside 213's geographic footprint. The recurrence is a function of how mobile phone numbers and their associated address records are in California: porting between carriers, prior registrations, and address overlaps move records across the state without regard to area-code boundaries. The directory holds detailed records on 455 distinct prefixes within 213, a working subset of the active prefix population, which is larger.

Los Angeles is dominated demographically by its population scale: the city sits among the most populous in the country, several million within city limits and a metropolitan area many times larger. Household income runs close to the US median, while home values come in dramatically higher — typical residences carry valuations several times the national figure, a defining feature of the Los Angeles housing market relative to most US cities.
