Thousands of people have been warned they have just weeks left to take action or face seeing their benefit payments stopped.
Around 7,500 people are still claiming Tax Credits, Child Benefit and Guardians' Allowance into a POC account - but that will stop on April 5.
Anyone with wit a POC (Post Office Card) account has to tell HMRC where they would like the money sent instead once the scheme ends on April 5.
