If you'd like to reassure yourself that the text you've received is from Nationwide, you can call us on the main enquiries number - 0800 30 20 11 - and ask to be put through to the agent that contacted you. They will always leave their full name.
If you have a current account, mortgage, personal loan or credit card with us, we might text you asking you to go to our Payment Assistance website to make a payment or update your contact details.
