The most-reported numbers right now
Ranked by independent complaint count in the current data window. "Robocalls" counts how many of those complaints specifically flagged a recorded message or auto-dialer, and "top category" is the most common reason given across all complaints against that number.

How this list is built
This page runs no manual curation and accepts no submissions — every row comes directly from a fresh pull of the FTC's public Do Not Call Reported Calls API at build time, the same government complaint data consumers generate by filing reports at reportfraud.ftc.gov and donotcall.gov. The pipeline aggregates individual complaints by the reported caller's phone number, counts how many are independently flagged as a recorded message or robocall, and tracks the most frequent complaint category and most recent report date. Numbers are ranked purely by complaint volume — there is no way to pay, request, or otherwise influence placement on this list, which is exactly what makes it a trustworthy signal rather than an advertisement dressed up as a warning.
Why a number appears here (and why yours might not)
A number needs multiple independent complaints within the current window to surface on this page at all — a single report, even a legitimate one, isn't enough to rank here, which mirrors how the main lookup tool's own spam gauge treats individual reports as a data point rather than a verdict. That threshold cuts both ways: a number that called you once and isn't listed here may still be a scam operation simply too new or too low-volume to have accumulated enough complaints yet, while a listed number reflects real, independently-filed complaints from people with no connection to each other. Treat this page as "numbers with strong existing evidence," and the reverse lookup as the tool for "check this specific number I actually received a call from," whether or not it happens to appear below.
Common categories behind these calls
Individual complaint subjects vary, but aggregated across every currently-flagged number, a small number of categories account for most of the volume:
| Category | Share of all reports |
|---|---|
| Reducing your debt (credit cards, mortgage, student loans) | 26% |
| Calls pretending to be government, businesses, or family and friends | 9.6% |
| Dropped call or no message | 7.3% |
| Medical & prescriptions | 6.3% |
| Home improvement & cleaning | 1.9% |
| Warranties & protection plans | 1.3% |
| Vacation & timeshares | 0.7% |
| Energy, solar, & utilities | 0.5% |
Debt-relief and credit-reduction pitches ("lower your credit card interest," "your student loans qualify for forgiveness") are the single largest identifiable category by a wide margin — well ahead of the government-imposter and business-impersonation calls that get more media attention. A large share of complaints are also filed with no specific category or a generic "other," reflecting real-world complaint filing rather than a gap in this site's data — people report first and categorize precisely second, if at all.

What to do if you got a call from one of these numbers
The response is the same regardless of which category the number falls into:
- Don't call it back and don't engage further if you already answered — hang up rather than trying to "reason" with an autodialer or a script-reading agent.
- Never use a callback number the caller provided. If they claimed to be a real company or agency, find that organization's number independently — your card, your bill, the official website you type in yourself — and call that instead.
- Run the number through the reverse lookup for carrier, line type and current spam data, especially if it isn't on this page — most numbers that call people never accumulate enough complaints to surface here.
- File your own report at reportfraud.ftc.gov. This isn't symbolic — it's the exact same pipeline that populates this page, so your report becomes part of the next person's data point.
- Block the number on your device and consider your carrier's free call-filtering app — see the full robocall-blocking guide for every layer that actually works.
Frequently asked questions
Is this a complete list of every scam number?
No — it is impossible for any list to be complete, because operations rotate through spoofed and disposable numbers constantly, often discarding a number within days. This page shows the numbers with the most independent FTC complaints in a recent rolling window, which is a genuinely useful signal but never an exhaustive registry. Always check the specific number that called you with the free reverse lookup rather than only scanning this list.
Where does this data actually come from?
The Federal Trade Commission's public Do Not Call (DNC) Reported Calls dataset — the same government complaint records consumers file at reportfraud.ftc.gov and donotcall.gov. Nothing here is guessed, scraped from forums, or crowd-sourced from unverified posts — it is aggregated directly from the FTC's own published API.
How often is this list updated?
This page is regenerated at every site build directly from a fresh pull of the FTC's public dataset, covering roughly the last 14 days of reports. The version you're reading was generated on July 4, 2026. Because the underlying complaint volume changes daily, treat the specific ranking as a snapshot rather than a permanent registry.
A number on this list called me — what should I do?
Don't call it back, and don't engage if you already answered. If it claimed to be a specific company or agency, hang up and contact that organization directly using a number you looked up yourself, never the one that called you. File your own report at reportfraud.ftc.gov so the next person's lookup carries your data point too.
Why is a number I know is legitimate showing report history?
Toll-free and VoIP numbers are sometimes reassigned or briefly spoofed by unrelated bad actors before a legitimate company is issued the same digits, and a handful of legitimate telemarketers do generate genuine complaints for aggressive-but-technically-legal cold calling. Report history is a strong caution signal, not an automatic guilty verdict — cross-check the carrier and line type with the carrier lookup before concluding anything.
Can I get my own number removed from lists like this?
This page only ever shows numbers that cleared a real, independent complaint threshold in the FTC's own data — it doesn't accept manual removal requests, because doing so would undermine the one thing that makes the list trustworthy (nobody can pay or ask their way off a government complaint count). If you believe a number is listed in error, the more useful action is registering it at donotcall.gov and ensuring future calls from it are legitimate and compliant.
