What Is a Los Angeles Phone Area Code?

A Los Angeles phone area code is the three-digit prefix used in the North American telephone numbering system to identify a geographic region within Los Angeles and surrounding areas.

It appears at the beginning of a 10-digit phone number.

Example

• 555 = Exchange code

• 1234 = Subscriber number

Area codes allow telecom providers to route calls efficiently across cities, states, and countries.

Every smartphone requires its own phone number, dramatically increasing demand.

History of Los Angeles Area Codes

Understanding the history helps explain why Los Angeles now uses many codes.

1947: The First Area Code

When the North American Numbering Plan was introduced, Los Angeles used just one area code: 213.

It covered almost the entire Southern California region.

1980s–1990s: First Splits

This method is known as an area code split.

2000s: Overlay System Introduced
