What kind of number is 07700 900 123?
07700 900 123 is a structurally valid UK number, but its specific range doesn't currently appear as allocated in our copy of Ofcom's National Telephone Numbering Plan. That can mean the range is newly issued, reserved, or being presented by a spoofed caller ID — treat unexpected calls from it with extra care.
Is it safe to answer or call back 07700 900 123?
Keep in mind that a phone number is a clue, not proof of identity. UK caller IDs can be forged (spoofed) by VoIP systems anywhere in the world, and legitimate numbers are sometimes hijacked for short scam campaigns then abandoned. Judge each call on its substance: a genuine organisation will happily let you hang up and call back via the number on its official website.
What to do if 07700 900 123 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.

Look the number up first (you're in the right place), and if it matters, the caller will leave a voicemail or try again.
