+44 7 mobile number scams

Updated 2026-05-02

All UK mobile numbers begin 07 (or +44 7 internationally). Scammers favour mobile prefixes for SMS phishing because messages are cheap to send in bulk and harder to trace than landlines.

Common 07 scam patterns

Royal Mail 'redelivery fee' texts, HMRC 'tax refund' messages, parcel courier impersonation, and 'Hi mum, I've lost my phone' WhatsApp scams all originate from 07 numbers or short codes. The number changes daily as networks block them.

Are 07 numbers traceable?

Pay-as-you-go SIMs can be bought with cash and discarded. By the time a scam SMS is reported, the number is often inactive. That's why community reporting via WhoCalledMe.ai matters — it's faster than carrier takedowns.

Red flags

  • 07 number sending messages claiming to be a company (Royal Mail, HMRC, banks)
  • Asks you to click a link to pay or verify
  • Family-emergency message from an unknown 07 number

What to do

  1. Forward the text to 7726.
  2. Block the number.
  3. If a 'family member' messages from a new number, call them on their known number first.
  4. Search the number on WhoCalledMe.ai before responding.
