Are all reported 001 International Telecom 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 001 International Telecom can have ported away years ago while keeping the same digits. Calls from numbers on this list might not actually be coming through 001 International Telecom’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 001 International Telecom-allocated CLIs whose unfamiliar number surprised the recipient. Others are active scam campaigns spoofing or originating on 001 International Telecom 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.
No reports filed against 001 International Telecom yet
Nobody has filed a community report on a 001 International Telecom-allocated number so far. That is not a clean bill of health — it usually just means 001 International Telecom’s blocks haven’t crossed a reporter’s path yet, or that calls from them are being recognised and answered normally. When the first report is approved it will appear here automatically, broken down by the community category it was filed under and measured against the ranges 001 International Telecom owns.
In the meantime, the universal red flag on any UK call — whichever Range Holder the number sits in — is pressure to act now: a request to move money, install software, or read back a one-time passcode on a call you didn’t start.

FAQs about 001 International Telecom reported numbers
Are these definitely 001 International Telecom's numbers?
They are numbers from blocks Ofcom originally allocated to 001 International Telecom. UK numbers can be ported between networks while keeping the same digits, so the live carrier on any specific number may be different today. The per-number page (click any row) shows both the Range Holder and the live AI internet check, which together are the strongest free signal for the actual caller.
Should I block 001 International Telecom numbers in general?
No — that would block a vast amount of legitimate UK traffic. 001 International Telecom blocks contain everything from consumer mobile phones to business landlines to contact centres. Block specific numbers only after reading the per-number report. iOS and Android both let you block individual CLIs without affecting the rest of the network.
I got a call from a 001 International Telecom number — what should I do?
Don't call back from the number on your screen. Look up the supposed organisation's official phone number on their website and dial that instead. If the caller claimed to be your bank, dial 159 (the UK Stop Scams switchboard) to get safely to your bank's fraud team without trusting the CLI. Add a community report afterwards so the next person to get the same call sees your evidence.
