Los Angeles County Phone Directory

Los Angeles County phone directory resources span dozens of free and low cost databases that help you find people, phone numbers, and contact details across the largest county in the United States. With more than 10 million residents and a court system that holds case records going back to the early 1980s, Los Angeles County gives the public strong access to search tools for property, court, and vital records. The county runs its own assessor portal, a registrar-recorder office, the LA Superior Court case search, and a sheriff inmate lookup. All of these tools work as part of the broader Los Angeles County phone directory system that anyone can use online or in person at county offices.

Los Angeles County Property Phone Directory

The LA County Assessor runs one of the largest property search tools in the state. You can use it to find names tied to property in Los Angeles County.

The assessor sits in Kenneth Hahn Hall of Administration at 500 West Temple Street, Room 320, Los Angeles, CA 90012. Call (213) 974-3211 for help. The toll free line is (888) 807-2111.

The LA County Assessor Portal lets you search property assessment data for any parcel in the county.

Results show assessed values and owner names. This is free to use and covers all of Los Angeles County. The data updates each tax year. Property records like these form a core part of the Los Angeles County phone directory because they connect names to addresses throughout the region. For people who need to track down a property owner or check who lives at a certain address, the assessor tool gives fast answers without any fees.

Note: The assessor portal does not show phone numbers directly, but it links names to addresses which can help with other Los Angeles County phone directory searches.

LA County Registrar-Recorder Directory

The Los Angeles County Registrar-Recorder/County Clerk handles vital records, recorded documents, and elections for the county. This office is a key part of the Los Angeles County phone directory for anyone who needs birth, death, or marriage records. Fees changed on January 1, 2026 under AB 64. Birth certificates now cost $34. Death certificates cost $26. Marriage certificates cost $19. The main office is at 12400 East Imperial Highway, Room 1002, Norwalk, CA 90650.

The portal covers vital records, document recording, and voter services for all of Los Angeles County.

Vital records tell you a lot about a person. A birth record has the full name, date of birth, and the names of the parents. A marriage record shows both spouses and the date of the event. A death record lists the name, date, and place of death. These records are part of the public file in most cases, and they help fill in gaps when you are doing a Los Angeles County phone directory search. You can order copies by mail or in person at the Norwalk office. Online orders go through a third party service.

Los Angeles Court Records Phone Directory Search

LA Superior Court has an online case search that covers civil, criminal, family law, probate, and small claims cases. It is one of the best tools in the Los Angeles County phone directory for finding people who have been part of court cases. A name search costs $4.75.

The Civil Case Index covers general jurisdiction civil, limited civil, probate, family law, and small claims cases in Los Angeles County.

This tool lets you look up cases by name and see the case number, filing date, and type. It covers decades of Los Angeles County court history and is a key resource for phone directory research in the county.

The Criminal Case Search is separate from the civil index. It holds felony and misdemeanor cases filed in Los Angeles County courts.

Criminal case results show charges, hearing dates, and case status. Names in these records often match people you might search for in the Los Angeles County phone directory. Both the civil and criminal search tools require a credit card to use, but the costs are low compared to most private search services.

Note: Court records in Los Angeles County do not include juvenile cases or sealed files, so some results will not show up in a phone directory search.
