Withholding your telephone number means that it won’t be available to the person you’re calling. You can ask us to permanently withhold your number, or you can choose to withhold it yourself on a call-by-call basis.
- To withhold your number on individual calls, just dial 141 before the telephone number you want to call.
- To withhold your number on all calls, you’ll need to contact us on 0330 123 4150 to add (or remove) this service.
If you choose to withhold your number on all calls, you might want to release it if you're calling your doctor or a business. Some of them won't accept a call if the number's withheld. You can do this by entering 1470 before the number you wish to call.
Both services are free of charge.
