City population is shown in full. The share of each city inside 310 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.

What counties does area code 310 cover?

1,891,605 residents across 1 county, counted inside the 310 boundary — a county split between codes contributes only its part.

Sources: City populations – U.S. Census Bureau PEP, Vintage 2024 (SUB-IP-EST2024-POP). State populations – the same program, Vintage 2025 (CO-EST2025-ALLDATA). Area-code footprint and county populations – 2020 Census Centers of Population, mapped against NANP area code boundaries. The share of each city inside a code is measured the same way, against Census place boundaries from the Census Bureau's TIGERweb service. Area code assignments – NANPA CO Code data.

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.

Frequently Asked Questions about the 310 Area Code

Who called me from a 310 number?

A 310 number is assigned to Los Angeles, California, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 310 code to look nearby, so a 310 number doesn't prove the caller is local. Recently, 979 unwanted-call complaints were reported to the FTC for numbers showing the 310 code (53% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 310 a scam area code?

No area code is a scam on its own. 310 is a normal, officially assigned code for Los Angeles, California. Spam callers spoof local codes to raise the odds you answer, so 310 on your caller ID says nothing about who is really calling. Recently, 979 unwanted-call complaints were reported to the FTC for numbers showing the 310 code (53% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 310 area code?

Repeated calls from different 310 numbers are usually spoofing: a robocaller rotates through 310 numbers so each call looks local and slips past simple blocks. Recently, 979 unwanted-call complaints were reported to the FTC for numbers showing the 310 code (53% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.

Should I answer an unknown 310 number?

If you aren't expecting a 310 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.

How do I block calls from the 310 area code?

Block a single 310 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 310 code also stops legitimate local calls, so use it only as a last resort.

Where is area code 310?

Area code 310 covers Los Angeles and the surrounding area in California, spanning 34 cities with about 1,891,605 residents. It shares its area with overlay code 424.

When did area code 310 go into service?

Area code 310 went into service on November 2, 1991. It was split off from area code 213.

Is 310 a real area code?

Yes. 310 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Los Angeles, California. A real code can still show up on spoofed spam calls, so treat unknown 310 calls with normal caution.

What timezone is the 310 area code in?

The 310 area code is in the Pacific Time (PT). Because a number can be kept when someone moves or switches to VoIP, a specific 310 caller may not be in that zone.

How do I call a 310 number from abroad?

From outside the US, dial your country's exit code, then 1 (the US country code), then 310 and the seven-digit number. From a mobile phone you can usually just enter +1 310 followed by the number and let the phone add the exit code for you.
