Is it safe to answer or call back 01603 512769?
Whatever the caller ID says, remember UK numbers can be spoofed: scammers can present any number, including real ones belonging to banks and government bodies. The reliable test is never the number itself — it's what the caller asks you to do. Pressure, urgency, requests for security details or unusual payment methods are the red flags that matter.
What to do if 01603 512769 called you
- Don't act on the call alone. If the caller claimed to be your bank, HMRC, a courier or a utility, hang up and contact the organisation on a number you find yourself — never one the caller gives you. For banks, dial 159.
- Never share security details. Full passwords, PINs and one-time passcodes are never requested by legitimate UK organisations on an outbound call.
- Don't return a missed call you don't recognise. One-ring 'wangiri' scams rely on call-backs, sometimes routed to premium-rate lines.
- Report what happened. Use the report form above to warn other UK users, and report fraud attempts to Action Fraud (or 101 in Scotland).
- If money or details were given, contact your bank immediately on 159 and report to Action Fraud.
