Royal Mail will oblige consumers to pass back and forth stamps for the equal value of new barcoded ones.
The postal group is advancing to new universal product code stamps as part of its innovative drive, which also includes added safety characteristics and new services.
As part of the drive, Royal Mail has catapulted a blue print that will let consumers give and take regular stamps for barcoded ones.
Non-barcoded stamps will remain valid and hold until February 2023.
The advancement will let consumers view and apportion tape recording by checking out the new universal product stamps in the Royal Mail App.
Permitted stamps are the regular first and second class "everyday" stamps.
Nick Landon, Royal Mail's chief commercial officer, said: "As we move to this exciting new era of barcoded stamps, please check your kitchen drawers, wallets and purses for older non-barcoded stamps and make sure you use them up by 31 January 2023.
"If you can't use them up by then, we have set up a swap out scheme as a simple way to swap your old stamps for our new, digitally-enabled ones. Welcome to the new world of barcoded stamps."
