Documented patterns behind 877-looking calls
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.
Bank / fraud department impersonation
The caller pretends to be your bank's fraud department 'confirming suspicious activity'. The real goal is your online banking credentials, card number, or a real-time transfer authorization (often via Zelle or wire).
Amazon / big-brand imposter robocall
A robocall claims a large purchase or suspicious activity on your Amazon (or other retailer) account and asks you to 'press 1' to dispute it, connecting you to an agent who harvests card and login data.
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.
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.
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.
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.

FAQ
Are all calls from 877 numbers scams?
No — 877 is used by countless legitimate businesses. 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 877 area code?
Some phones and carrier apps allow prefix-based blocking, but scammers rotate codes (including overlays 800, 888, 866, 855, 844, 833), so blanket blocking mostly costs you legitimate calls. Silencing unknown callers works better.
Where do I report a scam call from a 877 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.
