Scam calls from 240 numbers

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

A 240 caller ID is easy to fake. Neighbor spoofing — matching your area code and even your prefix — is designed to get local-looking calls answered. The schemes below are documented by the FTC and FCC and map what typically hides behind such calls.

Note that Washington numbers may also show overlay codes 227, 301 — a scammer rotating through the 227/240/301 complex still looks "local".

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

Documented patterns behind 240-looking calls

Immigration (USCIS) impersonation

Callers impersonate USCIS or 'immigration officers', claim a problem with your status or paperwork, and demand payment or personal information under threat of deportation.

Signs: threats of deportation unless a 'fee' is paid by phone; spoofed caller id showing uscis numbers. Full pattern →

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.

Signs: recording about an order you never placed; transfer to an 'agent' who asks for card numbers or remote access. Full pattern →

Caller ID spoofing

The caller deliberately falsifies the number shown on your caller ID display to disguise their identity, often imitating a local number, a government agency, or a well-known company.

Signs: the displayed number looks local or familiar, but the caller is a stranger or a recording; a callback to the displayed number reaches someone who never called you. Full pattern →

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 →

FAQ

Are all calls from 240 numbers scams?

No — 785 real prefixes serve Washington 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 240 area code?

Some phones and carrier apps allow prefix-based blocking, but scammers rotate codes (including overlays 227, 301), so blanket blocking mostly costs you legitimate calls. Silencing unknown callers works better.

Where do I report a scam call from a 240 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.
