Quick answer

Los Angeles uses multiple area codes: 213, 323, 738, 310, 424, 818, 747. The listed codes use Pacific Time. Overlay codes may serve the same geographic footprint, and some codes can extend beyond city boundaries.

Important limitation

A city-to-area-code list is not a reverse-phone identity service. Mobile numbers can be retained after a move, and an area code alone cannot establish where a person currently lives or whether a caller is trustworthy.

Area Code Lookup is a free informational utility. It does not require an account, place advertising cookies, or sell personal information.

Information the tool uses

Lookup text is sent to this site only to return a result. The application does not ask for GPS access, contacts, a phone number owner, or a street address. Recent lookups are stored only in your browser using local storage and can be removed by clearing site data.

Server and network logs

Cloudflare may process ordinary request information needed to deliver and protect the site, such as IP address, request path, browser information, timestamps, and security signals. We do not use that information to identify the owner of a telephone number.

Data accuracy

Area-code status, state or territory, overlay relationships, service type, and in-service dates are derived from the NANPA NPA database. An area code can cover many communities, and a city label is a practical lookup aid rather than proof that a specific number or caller is physically located there.

Acceptable use

You may use the site for lawful informational purposes. Do not interfere with the service, attempt to bypass safeguards, or use automated traffic in a way that degrades access for others.

No warranty

The service is provided “as is.” Numbering plans change, and no result should be treated as emergency, legal, financial, identity, or fraud-verification advice.
