How to report a scam call in the UK

Updated 2026-05-02

Reporting scam calls makes a real difference: networks use the data to block ranges, regulators build prosecution cases, and platforms like WhoCalledMe.ai warn the next person. Here's the fastest, most useful way to report.

Action Fraud (the national reporting centre)

If you've lost money or shared sensitive information, report to Action Fraud at actionfraud.police.uk or 0300 123 2040. They issue a crime reference number and pass cases to the National Fraud Intelligence Bureau.

7726 (suspicious texts and calls)

Forward suspicious texts to 7726 — it spells SPAM on a phone keypad and is free on every UK network. For nuisance calls, dial 7726 and tell the automated service the number that called you.

Ofcom and the Telephone Preference Service

Register your number free on tpsonline.org.uk to opt out of legitimate marketing. After 28 days, unsolicited marketing calls become illegal and reportable to the ICO at ico.org.uk.

Your network

BT, Sky, Virgin, EE, Vodafone, O2, and Three all run scam-call reporting and blocking services — usually via a dedicated phone app or short code.

What to do

  1. Note the number, date, time, and what was said.
  2. Forward texts to 7726.
  3. Report calls to your network's spam line.
  4. If money or data was lost, call Action Fraud.
  5. Add the number to WhoCalledMe.ai so others are warned.

Frequently asked questions

Will the police call me back?

Action Fraud rarely follows up individually. They aggregate reports for pattern analysis and investigation by regional fraud teams.

Can I report a number that didn't take any money?

Yes — Action Fraud and 7726 both accept attempted-scam reports, and they're crucial for spotting new campaigns early.
