Scam calls from 527 numbers

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

Scam calls that display a NANP AREA 527 number usually do not originate there. Spoofing lets a caller present any digits, and 527 offers plenty of plausible-looking combinations. Below are the documented schemes most commonly reported behind local-looking calls.

Note that NANP AREA numbers may also show overlay codes 500, 533, 544, 566, 577, 588, 521, 522, 523, 524, 525, 526, 528, 529, 532, 538, 542 — a scammer rotating through the 500/521/522/523/524/525/526/527/528/529/532/533/538/542/544/566/577/588 complex still looks "local".

Reporting matters — FTC and FCC complaints are aggregated into enforcement actions against robocall operations.

Documented patterns behind 527-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 →

One-ring (Wangiri) callback scam

Your phone rings once and stops. The scammer hopes curiosity makes you call back a number that routes to an international premium-rate line, generating per-minute charges that are shared with the scammer.

Signs: a missed call that rang only once, often late at night; repeated one-ring calls from the same or similar numbers. Full pattern →

IRS impersonation

A caller claims to be from the Internal Revenue Service, says you owe back taxes, and threatens arrest, deportation, or license revocation unless you pay immediately — typically by gift card, wire transfer, or cryptocurrency.

Signs: demands for immediate payment by gift card, prepaid debit card, wire, or crypto; threats of arrest or lawsuits for unpaid taxes. Full pattern →

Social Security impersonation

The caller pretends to be from the Social Security Administration and claims your Social Security number has been suspended or linked to a crime, pressuring you to confirm the number or move money to 'protect' it.

Signs: claims that your ssn has been 'suspended' — ssns are never suspended; requests to confirm your ssn or move money to gift cards or crypto for 'safekeeping'. Full pattern →

Tech support scam

A caller claims to be from Microsoft, Apple, or another tech company and says your computer is infected. The goal is remote access to your device, payment for fake repairs, or installation of malware.

Signs: unsolicited call about a virus or hacked account; requests to install remote-access software (anydesk, teamviewer, etc.). Full pattern →

Family emergency ('grandparent') scam

The caller poses as a grandchild or other relative in trouble — an accident, an arrest abroad — or as a lawyer or officer calling on their behalf, and begs for urgent, secret payment. Voice-cloning tools have made these calls more convincing.

Signs: urgent plea for money from a 'relative' who asks you to keep it secret; payment requested via gift cards, wire transfer, crypto, or cash couriers. Full pattern →

FAQ

Are all calls from 527 numbers scams?

No — 0 real prefixes serve NANP AREA 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 527 area code?

Some phones and carrier apps allow prefix-based blocking, but scammers rotate codes (including overlays 500, 533, 544, 566, 577, 588, 521, 522, 523, 524, 525, 526, 528, 529, 532, 538, 542), so blanket blocking mostly costs you legitimate calls. Silencing unknown callers works better.

Where do I report a scam call from a 527 number?
