City population is shown in full. The share of each city inside 951 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 951 cover?
1,920,770 residents across 1 county, counted inside the 951 boundary — a county split between codes contributes only its part.
| County | State | Population in 951 | % of area-code footprint | % of County |
|---|---|---|---|---|

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 951 Area Code
Who called me from a 951 number?
A 951 number is assigned to Riverside, California, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 951 code to look nearby, so a 951 number doesn't prove the caller is local. Recently, 1,335 unwanted-call complaints were reported to the FTC for numbers showing the 951 code (48% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 951 a scam area code?
No area code is a scam on its own. 951 is a normal, officially assigned code for Riverside, California. Spam callers spoof local codes to raise the odds you answer, so 951 on your caller ID says nothing about who is really calling. Recently, 1,335 unwanted-call complaints were reported to the FTC for numbers showing the 951 code (48% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 951 area code?
Repeated calls from different 951 numbers are usually spoofing: a robocaller rotates through 951 numbers so each call looks local and slips past simple blocks. Recently, 1,335 unwanted-call complaints were reported to the FTC for numbers showing the 951 code (48% 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 951 number?
If you aren't expecting a 951 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 951 area code?
Block a single 951 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 951 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 951?
Area code 951 covers Riverside and the surrounding area in California, spanning 54 cities with about 1,920,770 residents. No other code overlays this region, so 951 alone identifies the area.
When did area code 951 go into service?
Area code 951 went into service on July 17, 2004. It was split off from area code 909.
Is 951 a real area code?
Yes. 951 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Riverside, California. A real code can still show up on spoofed spam calls, so treat unknown 951 calls with normal caution.
