Across the UK, many people still discover unused postage stamps in drawers, filing cabinets, wallets, or old stationery boxes. When it comes time to post a letter, legal document, or greeting card, a common question arises: can you still use old stamps in 2026 under current Royal Mail rules? Despite the passage of time since the introduction of barcoded stamps, confusion has not completely disappeared.
In 2026, the rules are clearer than ever, but misunderstandings remain common. Some stamps are still fully valid, while others are no longer accepted for postage. This guide provides a precise, up-to-date explanation of can you still use old stamps in the UK, helping households and businesses avoid delays, surcharges, and unnecessary mistakes.
Why Royal Mail Introduced Barcoded Stamps
Royal Mail introduced barcoded stamps to modernise the UK postal system and improve long-term security. Before barcodes were introduced, traditional stamps were vulnerable to reuse and counterfeiting, creating financial losses and inefficiencies within automated sorting centres.
Barcodes allow each stamp to be scanned and verified digitally as it moves through the postal network. This supports accurate processing, reduces fraud, and enables future digital services. While the transition improved reliability overall, it also changed which stamps remain valid, making it essential for users to understand the rules that apply in 2026.
Can You Still Use Old Stamps in 2026?
The short answer to can you still use old stamps is: sometimes. In 2026, stamp validity depends on the type of stamp, not how old it is. Some stamps issued many years ago remain valid, while others are no longer accepted for postage.
Everyday first- and second-class stamps without a barcode are no longer valid in 2026. Using them can result in mail being delayed or surcharged. However, many older stamps, including commemorative stamps and certain Christmas issues, are still valid and can be used without any problem. Understanding this distinction is essential for posting mail correctly.
Non-Barcoded Everyday Stamps Explained
Non-barcoded everyday stamps are the most commonly found stamps in UK homes. These are the plain first- and second-class stamps that were widely sold for routine correspondence before barcodes were introduced. Although they still look official, Royal Mail no longer accepts them as valid postage.
Adding extra stamps or exceeding the required postage value does not make these stamps usable. An invalid stamp remains invalid regardless of its face value. Letters posted with these stamps may still travel part of the way through the system but are likely to be flagged during processing, leading to additional charges for the recipient.
Queen Elizabeth II Stamps and Ongoing Confusion
Stamps featuring Queen Elizabeth II remain a major source of uncertainty. Many people assume that all Queen’s head stamps became invalid, while others believe they are all still usable. In reality, the deciding factor is the purpose of the stamp, not the monarch shown.
Commemorative Queen Elizabeth II stamps, issued to mark historical events, anniversaries, or cultural themes, remain valid in 2026. Plain everyday Queen’s head stamps without barcodes are not valid. Being able to identify whether a stamp is commemorative or an everyday issue helps prevent posting errors.
Barcoded Stamps and Their Continued Validity
Barcoded stamps are now the standard form of UK postage and remain fully valid in 2026. Whether they feature King Charles III, commemorative artwork, or special designs, the barcode ensures the stamp can be processed correctly.
However, barcodes must be intact and readable. Stamps that are damaged, heavily creased, or obscured by ink may not scan properly and could cause delays. For important or time-sensitive mail, using new barcoded stamps or purchasing postage directly from a Post Office provides additional peace of mind.
What Happens If You Use an Invalid Stamp
If you use an invalid non-barcoded stamp in 2026, Royal Mail may issue a “fee to pay” notice to the recipient. The recipient must pay a surcharge before the item is delivered, which can be inconvenient and frustrating.
The fee is often higher than the cost of a valid stamp and can damage relationships or professional credibility. For businesses, repeated postage errors can lead to customer dissatisfaction. Checking whether you can still use old stamps before posting is a simple but important step.
Using Old Stamps for Cards, Invitations, and Letters
Many people still ask whether they can use old stamps on birthday cards, wedding invitations, or personal letters. While it may seem harmless, using invalid stamps increases the risk of delays, particularly during busy periods.
High mail volumes mean stricter reliance on automated processing, where invalid stamps are more likely to be detected. To avoid issues, it is safest to use barcoded stamps or confirm that older stamps are commemorative or Christmas issues that remain valid.
The Royal Mail Stamp Swap Scheme in 2026
Royal Mail continues to operate the Stamp Swap Scheme, allowing customers to exchange non-barcoded everyday stamps for barcoded versions of equal value. This ensures no financial loss and provides a practical solution for those who still hold unused invalid stamps.
The scheme is particularly useful for households, charities, and small businesses that purchased stamps in bulk before barcodes were introduced. Instead of discarding them, users can convert them into valid postage suitable for use in 2026.
How the Stamp Swap Process Works
To use the Stamp Swap Scheme, customers must complete a swap form and send their non-barcoded stamps to Royal Mail using a Freepost address. There is no cost for postage when submitting the form and stamps.
Post Offices do not exchange stamps at the counter, which often surprises customers. The swap must be completed through Royal Mail’s official process. Following the instructions carefully ensures replacement stamps are issued smoothly.
Do Old Stamps Expire?
A common misconception is that stamps have a universal expiry date. In reality, some stamps remain valid indefinitely, while others were withdrawn as part of the barcode transition.
In 2026, what matters most is stamp classification, not age. Advice that focuses only on old deadlines can be misleading. Checking whether a stamp is barcoded or commemorative is the most reliable way to determine if you can still use old stamps.
Common Myths About Old Stamps
One persistent myth is that stamps become invalid whenever postage prices increase. This is incorrect. Valid stamps remain valid regardless of price changes. Only specific categories, such as non-barcoded everyday stamps, are affected.
Another myth is that Royal Mail no longer accepts any old stamps. Many older stamps remain valid, including commemorative and Christmas issues. Understanding these myths helps prevent unnecessary disposal of usable postage.
Practical Checks Before Posting Mail
Before posting any letter or card, take a moment to inspect the stamp. Look for a barcode and assess whether the design suggests an everyday stamp or a special issue.
If you are unsure, purchasing barcoded stamps or seeking advice before posting reduces risk. These simple checks are particularly important for important documents where delays could cause inconvenience or financial loss.
