Scam & spam phone numbers: the most-reported numbers
The phone numbers reported most often in the FTC's Do Not Call complaint data — a data-backed list of the most-reported scam & spam numbers, with the spoofing caveat. Updated monthly.
Below are the phone numbers reported most often in the U.S. Federal Trade Commission's Do Not Call complaint data — drawn from 320,466 complaints filed against the 47,856 numbers reported most across 395 area codes. This is a live "list of scam phone numbers" in the sense people mean it — the numbers behind the most unwanted-call reports — but read the caveat first, because the truth about these numbers is more interesting than a blocklist.
What this data is — and isn't. These figures count consumer complaints in the U.S. Federal Trade Commission's Do Not Call database. They are unverified reports, not proof of wrongdoing. Crucially, most scam calls spoof a real number or a local area code, so a high complaint count usually means a number or area code is being imitated — the real owner is often a victim too. areacode.fyi is not a consumer reporting agency and this information is not for any FCRA purpose (employment, credit, tenant, or insurance screening). Report unwanted calls at DoNotCall.gov.

Why the worst offenders are almost all toll-free
Notice how many start with 833, 866, 855, 877, 888 or 844. Toll-free prefixes account for about 51% of all complaints in this data, because high-volume debt-relief and imposter robocall operations dial from toll-free lines. By contrast, scammers who want you to answer usually spoof a local number instead — see scam & spam area codes for why a local area code on your caller ID means very little, or spam calls by area code for the FTC complaint data ranked by state and geographic code.
The bigger picture: U.S. robocalls by the numbers
Robocalls ran about 4.7 billion a month in 2025 (YouMail Robocall Index), and 258.5 million numbers sit on the Do Not Call registry. The most-reported FTC topics were reducing debt, imposters, and medical & prescriptions; government-impersonation scams (fake toll and DMV texts) drove much of the record imposter losses, and local-number spoofing is up roughly 50% year over year (Nomorobo).
What to do about a number you don't recognize
- Don't assume the caller ID is real. Any number can be spoofed. Let unknown numbers go to voicemail.
- Look it up before calling back — search the full number on our who-called-me lookup.
- Never pay or share codes because of pressure or a threat. The FTC, IRS, banks and utilities do not work that way.
- Report it at DoNotCall.gov — those reports are exactly what feeds this data.

Frequently asked questions
Does a high complaint count mean a number is a scammer?
Not necessarily. Because most scam calls spoof a number, a high report count means a line is reported often — not that its real owner is a scammer. The real owner may be a victim of spoofing too.
Why are the most-reported numbers almost all toll-free?
Toll-free prefixes like 833, 866, 855, 877 and 888 account for about 51% of the complaints in this data, because high-volume debt-relief and imposter robocall operations dial from toll-free lines. Scammers who want you to answer usually spoof a local number instead.
Are toll-free numbers like 800, 833 or 888 scams?
A toll-free number is not automatically a scam — many belong to legitimate businesses. Toll-free prefixes dominate this list because robocallers dial them in bulk. Judge a call by what it asks for, and let unknown numbers go to voicemail.
What should I do about a number I don't recognize?
Don't assume the caller ID is real — any number can be spoofed. Let unknown numbers go to voicemail, look the full number up before calling back, never pay or share codes under pressure, and report unwanted calls at DoNotCall.gov.
