Guidance

Check genuine HMRC contact that uses more than one communication method

Check recent contacts from HMRC to help you decide if a suspicious email, phone call, text or letter could be a scam.

Sometimes HMRC uses more than one way to get in touch. For example, we may contact you by letter first before following up with an email, call or text message. This is because:

  • it can provide an extra level of security

  • these are the contact details HMRC has for you

All the HMRC contacts listed on this page can use more than one communication method. They are in alphabetical order.
