Scam calls from 951 numbers

Patterns documented by FTC/FCC · numbering data as of July 28, 2026.

Scam calls that display a Riverside-area 951 number usually do not originate there. Spoofing lets a caller present any digits, and 951, with its 686 active prefixes, offers plenty of plausible-looking combinations. Below are the documented schemes most commonly reported behind local-looking calls.

If any of these match a call you received, report it: the FTC's fraud reports and the FCC's complaint center are the channels that feed enforcement.

Documented patterns behind 951-looking calls

Neighbor spoofing

A form of caller ID spoofing in which the falsified number matches your own area code and often your NXX prefix, so the call appears to come from a nearby household and feels safe to answer.

Signs: the incoming number shares your area code and first three digits of your local number; answering leads to a robocall, silence, or a sales/scam pitch. Full pattern →

Utility shut-off scam

The caller claims to be from your electric, gas, or water company and threatens immediate disconnection unless an 'overdue balance' is paid within the hour, usually by prepaid card or payment app.

Signs: threat of shut-off within 30–60 minutes; payment accepted only via prepaid card, crypto atm, or payment app. Full pattern →

Jury duty / warrant scam

A caller posing as a sheriff's deputy or court officer says you missed jury duty and a warrant has been issued, but the 'fine' can be paid by phone to avoid arrest.

Signs: claim of an active arrest warrant resolvable by immediate phone payment; demands for gift cards, prepaid cards, or a wire. Full pattern →

Prize / lottery / sweepstakes scam

You are told you won a lottery or sweepstakes — often one you never entered — but must first pay 'taxes' or 'fees' to claim the prize. Real prizes never require upfront payment.

Signs: 'you've won' calls for contests you never entered; upfront fees, taxes, or customs charges to release winnings. Full pattern →

Fake debt collection

Callers try to collect debts you do not owe or that do not exist, using threats and refusing to provide written validation. Some impersonate law firms or 'process servers'.

Signs: refusal to send written validation of the debt; threats of arrest or lawsuits for a debt you don't recognize. Full pattern →

Auto warranty robocall

Prerecorded calls about your car's 'expiring warranty' push overpriced or worthless service contracts. The FCC has taken enforcement action against major auto-warranty robocall operations.

Signs: recording mentions 'your vehicle's extended warranty' without naming your car; pressure to 'press 1' to speak with a 'warranty specialist'. Full pattern →

FAQ

Are all calls from 951 numbers scams?

No — 686 real prefixes serve Riverside subscribers. The point is that the displayed code alone proves nothing either way; judge the call's content and verify independently.

Can I block the whole 951 area code?

Some phones and carrier apps allow prefix-based blocking, but scammers rotate codes, so blanket blocking mostly costs you legitimate calls. Silencing unknown callers works better.

Where do I report a scam call from a 951 number?

File at ReportFraud.ftc.gov (fraud and losses) and the FCC Consumer Complaint Center (spoofing and robocalls). Include the displayed number, date and what was said.
