BT scam & spam call reports

Are all reported BT numbers scams?

No. Two important things to keep in mind:

First, the “Range Holder” on a UK number is the provider Ofcom originally allocated the block to — not necessarily the network running the live call. UK numbers are portable, so a customer originally on BT can have ported away years ago while keeping the same digits. Calls from numbers on this list might not actually be coming through BT’s network today.

Second, a number on the leaderboard above is one that has been reported in the community. Reports are user-submitted and pass moderation (no defamatory accusations, no PII, no duplicates), but they are not the same as a confirmed fraud ruling. Some entries are genuine national contact-centres using BT-allocated CLIs whose unfamiliar number surprised the recipient. Others are active scam campaigns spoofing or originating on BT blocks.

Click any number above for the full per-number report: the Ofcom Range Holder confirmation, the area code (if geographic), the live AI internet check summarising public web reports, and the original community discussion. That combination of signals — not the rank on this leaderboard alone — is what should drive your decision about whether to call back.

What BT’s reports actually look like

Rather than a generic scam checklist, here is what the community has actually logged against BT-allocated numbers. There are 2 approved reports spread across 2 distinct numbers inside this holder’s ranges — a report rate of about 0 flagged numbers per 1,000 of the 37,372 blocks BT owns. None were filed in the last 30 days, so the current activity is historic rather than an active campaign. The most recent report was updated on 13 June 2026.

Sorted by the community category they were filed under, the reports on BT blocks break down as follows — “Bank impersonation” is the single biggest theme with 1 report:

• Bank impersonation — 1 report (50% of BT’s logged activity).
• HMRC and tax scams — 1 report (50% of BT’s logged activity).

That mix is specific to BT: it reflects which scam and nuisance patterns the community has actually tied to this holder’s numbers, not a UK-wide average. For the broader taxonomy of how these categories tend to play out, see our UK scam-call patterns guide.

How to report a BT number

If you’ve received a suspect call from a BT-allocated number, you can:

1. Start a community thread and tag the exact UK number. Once it passes moderation, it’ll appear on this leaderboard automatically.
2. Forward suspect texts to 7726 (free on every UK network). 7726 spells “SPAM” on a phone keypad and routes to Ofcom’s shared spam-reporting hub.
3. Report fraud to Action Fraud on 0300 123 2040 (or 101 Police Scotland). For the full reporting flow see our report a UK scam call guide.
