Martin Lewis, founder of MoneySavingExpert.com is warning people to use their 1st and 2nd class stamps ahead of 31st January 2023, when the they will no longer be accepted by Royal Mail, with the company moving to a new barcode system.

If you attempt to use these stamps after the 31st January 2023, you will be charged a surcharge, although no further details on the charge have been released yet.

Royal Mail has however confirmed that you will be able to exchange current stamps for barcoded ones for free under Royal Mail’s new ‘Swap Out’ scheme, which opens on 31 March 2022 and will run until 31 March 2023. 

Martin Lewis, founder of MoneySavingExpert.com, said: “For years, every time stamps go up in price I’ve suggested people stock up and bulk-buy in advance, as provided the stamp doesn’t have a price on it and instead just says the postage class, it’s still valid after the hike. This has been an effective tactic, as a first-class letter stamp is now 85p â€“ a decade ago it was just 60p. 

“So this change will come as a shock to the many stamp-hoarders out there. It’s the first time I can remember you’ve not been able to just lick it and stick it. And we don’t yet know if you’ll still be able to swap the stamps after March 2023, so this is a call to arms (or tongues) to ensure you either use ’em or swap ’em.”

From Royal Mail:

Following a successful national trial we will now be adding unique barcodes to all our regular ‘everyday’ Definitive and Christmas stamps. Each barcoded stamp will have a digital twin and the two will be connected by the Royal Mail App. The unique barcodes will facilitate operational efficiencies, enable the introduction of added security features and pave the way for innovative services for our customers.

Definitive stamps are the stamps that will be very familiar to most people. They feature the profile of HM The Queen. The barcodes match the stamp colour and sit alongside the main body of the stamp, separated by a simulated perforation line. The new barcode is an integral part of the stamp and must remain intact for the stamp to be valid.

Non-barcoded stamps will be phased out but will remain usable until 31 January 2023. Customers are encouraged to use their non-barcoded stamps before this date. Alternatively, non-barcoded stamps can be exchanged for the new barcoded version through Royal Mail’s ‘Swap Out’ scheme. 

The ‘Swap Out’ scheme will open on 31 March 2022. Forms will be available via a variety of channels, including local Customer Service Points; the Royal Mail website and via our Customer Experience team. Customers will be able to use a Freepost address. Further details will be announced shortly.
