This could still be a scam call

Criminals can make their number look like a genuine one (this is called spoofing). If someone calls from this number and asks for money, bank details, a code or passwords, hang up. Then call Nationwide Building Society back on the number on the back of your card, or call 159, which connects you to your bank.

Nationwide Building Society says: "We'll never ask you for your entire passnumber" (opens in a new tab)

What the provider and number type mean

Numbers starting 0800 and 0808 are freephone numbers, used by businesses, helplines, charities and government services.

Ofcom allocates phone numbers to communications providers in blocks. The provider shown is the one Ofcom allocated this block to. It is not the person or business that called you, and the number may since have moved to a different network, because people can usually keep their number when they switch provider. Ofcom does not hold information about individual numbers.

Ofcom says calls to 0800 and 0808 numbers are free from all consumer landlines and mobiles. If you are calling from a business line, check with your provider.
