What should I do after a suspicious call from a 0871 number?
084 and 087 calls include a service charge plus your provider’s access charge.
| Step | Action |
|---|---|
| 1 | Do not call back a number you cannot identify. If it rang once and cut off, that is often a test that your line is live. |
| 2 | If the caller said they were your bank, a company or the police, hang up and phone the organisation on a number you find yourself, or call 159 for your bank. |
| 3 | Forward suspicious text messages to 7726, free of charge. |
| 4 | If you lost money or shared details, contact your bank at once and report to Action Fraud (England, Wales and Northern Ireland) or Police Scotland. |
| 5 | For unwanted marketing calls, report to the ICO and block the number on your phone. |
| 6 | Calls to 01 and 02 numbers are charged at your provider’s standard landline rate (gov.uk/call-charges). |
| 7 | 084 and 087 calls include a service charge plus your provider’s access charge. |
