Where our data comes from

Data from the community

Every risk score comes from reports submitted by real people who received the call, not from purchased marketing databases.

How scores are calculated

Spam scores blend the safe, suspicious and spam ratings in community reports, and a number with only a few reports is held closer to neutral. More about spam scores.

Screened before it counts

New reports are screened before they affect a score, and suspect submissions are held for human review. About CallerCheck.

Built on community reports and UK safety guidance — CallerCheck combines reports from real users with risk scoring, moderation, and safety guidance informed by UK organisations such as Action Fraud, Ofcom, the ICO, the NCSC, 7726 spam-text reporting, and the 159 banking helpline where relevant.

It seemed legitimate to me; however, no one else seems to agree, and I declined to give personal info on this basis. If it is legitimate, it hurts in no way to go through proper channels instead of answering and giving info over the phone"

What Our AI Has Discovered

Our AI reads the approved community reports for a number and summarises the patterns it finds. It doesn't set spam scores, which come from the reports themselves, and every summary links to the reports behind it.

020 7126 8622 97% Risk

This London number on the Vodafone network is involved in banking impersonation scams. Reports consistently describe texts and calls falsely claiming to be from major UK banks including Halifax, Co-operative Bank, and Virgin Money, typically alerting victims to suspicious transactions or pending transfers of several hundred pounds. The scammers then direct people to call this number, attempting to trick them into confirming personal details or authorising fraudulent payments. A particularly concerning report details a scammer becoming aggressive when challenged and shifting between different bank identities mid-call. Do not call this number under any circumstances. If you receive similar messages, contact your bank directly using the number on your card or their official websiteβ€”never call a number provided in an unsolicited text or by a caller claiming to be from your bank.

Calls from this UK mobile number on the Three network look like a political outreach scam. The 19 reports describe spam or suspicious calls claiming to be from Reform UK, sometimes asking you to stand as a candidate or vote, with several noting an AI-generated voice or a distinctive accent. Some callers claimed to have your details, and one left a voicemail. Upvotes are not present, but the sheer volume of reports and the aggressive political angle add concern. If you didn’t expect political outreach, hang up, don’t share personal information, and consider blocking this number to avoid further calls.

01446 358122 98% Risk

This Barry-based number, carried by Simwood eSMS, is involved in impersonation scams targeting major UK banks. Reports consistently describe fraudulent texts and calls claiming to be from Barclays, Santander, and the Co-operative, often mentioning unauthorized payments to retailers like EasyJet and IKEA. Scammers use professional-sounding tactics, including authentic-sounding voiceovers and messages about call recording, to build trust before attempting fraud. The extremely high spam score and volume of consistent reports across different banking impersonations make this a serious fraud operation. Do not respond to messages from this number, do not click any links, and do not call back. If you receive contact claiming to be from your bank, hang up and call your bank directly using the number on your card or their official website.

020 4613 1964 83% Risk

Calls from this London number on BT are repeatedly described as spam and suspicious. With 18 reports, the pattern includes foreign or robotic voices, automated messages, and several calls in one day. Some reports mention scams about damp problems or loft insulation, and one claims impersonation of a company called BRS; others say the caller asks for your name and then hangs up. Upvotes are not recorded for these reports, so reliability is mixed, though the spam score is high at 83/100. If you answer, be cautious; this looks likely to be a scam. Do not share personal informationβ€”hang up, block the number, and verify through official channels.

Calls from this UK mobile number are repeatedly described as a DWP survey scam. Reports claim the caller pretends to be doing research or a survey for the Department for Work and Pensions, often about ESA, and sometimes after 7pm or on unusual days like Mother's Day. The carrier is listed as Tismi BV. With 17 reports, the concerns are consistent, though there are no upvotes/downvotes recorded here. Common red flags include unsolicited DWP survey claims, asking for details, and suggesting a follow-up by post. Given the high spam score (79/100), treat as suspicious. DWP survey scam β€” hang up immediately and verify with official DWP channels before sharing any information.

0151 6792335 96% Risk

Calls from this Liverpool-based number, routed through Core Telecom, are being reported as aggressive scam attempts posing as utility suppliers. Multiple reports say callers claim issues with your postcode or meter readings and press for your account number, previous invoices, or sensitive data. The tone is pushy and, in some cases, nasty. These are commonly used to obtain meter readings or account details. With 16 reports and a spam score of 96/100, the risk level is high risk; there are no upvotes or downvotes noted, so consensus is unclear. If you receive such calls, hang up immediately and do not share information. Verify any concerns with the supplier contact details on your bill or website, and block the number if persistent.

This London number on the Voxbone SA network has received multiple reports identifying it as a scam operation. One report mentions callers claiming to be from a bank, while another warns against calling regarding holiday offers. The consistent pattern across reportsβ€”with most describing straightforward scam activityβ€”suggests this is actively being used for fraudulent calls.

If you've received a call claiming to be from your bank, hang up and contact your bank directly using the number on your card or their official website.
