If you have a printer, and more than £200 worth of stamps to swap out then use the Bulk Stamp Swap Out form - here
If you don’t have access to a printer, you can request a Stamp Swap Out form to be posted to you by completing this form online. The instructions for sending back to us will depend on the form you request.
You can also pick up a 'Swap Out' form from your local Post Office along with a free post envelope – but the Post Office won’t be able to actually swap your stamps for barcoded ones - (please note they will only have the forms for the up to £200 option)
Or you can call our Customer Experience Team on 03457 740740.
‘Everyday’ non-barcoded stamps will no longer be valid after 31 January 2023. Royal Mail is encouraging its customers to use up these stamps by this date. While no longer valid after 31 January 2023, Royal Mail recently introduced a 6-month grace period where it will deliver these items as normal and will not apply a surcharge fee for insufficient postage. This period ends on 31 July 2023 and will allow its customers more time to use any of their remaining ‘everyday’ non-barcoded stamps.
