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 306,021 complaints filed against the 46,266 numbers reported most across 393 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 49% 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.
The bigger picture: U.S. robocalls by the numbers
- Americans received an estimated 52.5 billion robocalls in 2025 — about 4.7 billion a month, or roughly 1,600 every second (YouMail Robocall Index).
- The FTC logged 2.6 million Do Not Call complaints in fiscal year 2025, with 258.5 million numbers on the registry. Robocalls make up most complaints.
- The most-reported complaint topics were reducing debt, imposters (calls pretending to be government, business, or family), and medical & prescriptions.
- People reported losing $3.5 billion to imposter scams in 2025 — a record — out of about $16 billion in total reported fraud.
- 74% of 2025 robocalls used a fake local area code ("neighbor spoofing"), up roughly 50% from 2024 (Nomorobo) — which is why no single area code is safe to trust or block on sight.
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.
