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"

AI Insights

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 is a confirmed banking scam number based in London with a dangerously high spam score. Reports describe callers and texts impersonating multiple UK banksβ€”Halifax, Co-operative Bank, and Virgin Moneyβ€”claiming suspicious transactions have occurred on your account. The scammers use urgency tactics, telling you to call this number immediately to verify large transfers (often Β£800+) or claiming funds are waiting to be cleared. The consistent pattern across 31 reports shows this is a sophisticated operation targeting people's banking anxiety. Scammers may also claim you've been victims of fraud and pressure you to stay on the line, threatening that hanging up will prevent recovery of your money. This is completely falseβ€”legitimate banks will never contact you this way or demand you call a number they provide. Do not call this number under any circumstances. If you receive a suspicious banking text or call, hang up and contact your actual bank using the number on your card or their official website. Report the scam to Action Fraud immediately.

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

Calls from this Barry-based number appear to be linked to various scam attempts, particularly impersonating Barclays and Santander. Community reports consistently describe callers claiming to be from banks and referencing fake transactions, such as payments to EasyJet. The messages often include threats or urgent requests for action, which is typical of scam tactics. The spam score for this number is extremely high at 98/100, indicating it's widely viewed as problematic. Given the numerous reports and the lack of positive feedback, it's best to avoid engaging with this number. If you receive a call or text from them, hang up and do not provide any personal information.

020 4613 1964 83% Risk

This London number is generating multiple reports describing various scam attempts with a concerning pattern. Callers are using different tactics including asking "can you hear me?" to potentially record your voice, claiming to offer loft insulation services, and inquiring about property ownership or damp problems in your area. Several reports mention foreign-accented callers with poor English, robotic-sounding voices, and immediate hang-ups when questioned. The variety of approaches suggests this number is being used by scammers testing different scripts to find what works. Some calls are completely silent or just say "goodbye," which indicates automated systems checking active numbers. The consistent pattern across 18 reports, despite no community voting yet, shows this is an active scam operation that should be avoided completely. Never engage with these calls or provide any personal information - simply hang up and block the number.

07441425332 79% Risk

This UK mobile number, registered to Tismi BV, has a high spam score and is linked to unsolicited calls claiming to be from the DWP (Department for Work and Pensions). People are reporting that the callers request participation in a survey, with some calls happening late in the evening or on significant days like Mother's Day, which raises suspicion. Be cautious, as the DWP is unlikely to conduct surveys in this manner. It's always best to independently verify any communication supposedly from government agencies. Do not provide any personal information and consider reporting the call to the DWP and blocking the number.

0151 6792335 96% Risk

This Liverpool number is being used for utility company scams, with callers impersonating major energy suppliers like British Gas and Octopus. The scammers typically claim there's an issue with your postcode or billing information, then pressure you to verify account details or provide meter readings without offering proper identification themselves. Reports describe increasingly aggressive behaviour when people ask questions or refuse to cooperate. The callers use high-pressure tactics, claiming urgent billing problems need immediate resolution. One concerning report mentions harassment of elderly people using various area codes to appear legitimate. This is a clear utility impersonation scam designed to steal your personal information and account details. Genuine energy suppliers will never cold-call demanding immediate verification of sensitive information. If you receive this call, hang up immediately and contact your actual energy supplier directly using the number on your bill to verify any genuine issues.

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. Although individual reports haven't accumulated many upvotes yet, the volume and uniformity of warnings is notable. Do not engage with this number or return any calls from it. 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.
