From the introduction of the Penny Black in 1840, to barcoded stamps introduced in 2022, postage stamps have helped us keep connected across the UK and overseas.

Stamps make sending simple

Available individually, in books or in sheets if you need lots, stamps are the quickest and easiest way to send letters, cards and documents within the UK or abroad.

Buy your stamps from any of our 11,500 Post Office branches and use them whenever and wherever you need them. Pop a stamp on your envelope and post when it suits you – in branch or in one of over 115,000 Royal Mail post boxes around the UK. It’s simple and convenient.

How much does a stamp cost?

The price of a stamp depends on how quickly you want your letter to arrive and its size and weight.

For additional features like next day delivery, extra compensation, tracking or a signature on delivery you’ll need to ask in branch for Royal Mail Signed For or Special Delivery Guaranteed services.

New barcoded stamps

In February Royal Mail introduced barcodes to stamps. These will include regular ‘everyday’ Definitive stamps – the ones with the profile of HM The Queen, as well as Christmas stamps.

Each barcode is unique and an integral part of the stamp, so when using these new stamps you must keep the barcode attached otherwise they are invalid.

Stamps without a barcode can be used until 31 Jan 2023 and will continue to be sold until stocks are exhausted. Barcoded and non-barcoded stamps can be used together on one item if required.

Royal Mail are encouraging customers to use up their non-barcoded stamps before 31 Jan 2023. Where this is not possible, non-barcoded stamps can exchanged using Royal Mail’s ‘Swap Out’ scheme.

Please note, stamps cannot be exchanged in Post Office branches

Frequently asked questions about stamps

The barcode on the stamp will make every stamp unique. This will provide an additional security feature and enable Royal Mail to develop innovative customer services

All Definitive stamps are being barcoded — including Christmas stamps. Definitive stamps are the regular ‘everyday’ stamps featuring the profile of HM The Queen. Royal Mail are not barcoding special issue stamps — which are printed as a one off to commemorate a person/event and to celebrate the best of the UK’s contribution to the world.

Non-barcoded stamps can be used as postage up until 31 January 2023. If you won’t be able to use them up, you can send them to Royal Mail who will swap them out for barcoded stamps. The ‘Swap Out’ scheme will open on 31 March 2022. ​

‘Swap Out’ forms are not available in our Post Office branches, but are available from Royal Mail’s Customer Service Points, the Royal Mail website or by contacting the Royal Mail Customer Experience Team.

Two-dimensional (2D) barcodes look like squares or rectangles and they make each stamp unique providing an additional security layer. The barcode also enables Royal Mail to innovate and create new features such as linking to videos. There will be no personal held data in the barcode.​

If you post an item with a non-barcoded stamp after 31 January 2023 it will be liable to surcharge; the equivalent of it having no postage. Customers are advised to either use up any non-barcoded stamps or swap them out.​
