Royal Mail: 100 days left to use stamps without barcode

Royal Mail is urging people to use up stamps that do not have a barcode by 31 January, when they will no longer be valid.

Barcoded stamps were introduced in February to make deliveries more efficient and improve security.

Customers will still be able to use themed, commemorative and non-barcoded Christmas stamps after the deadline, the BBC reports.

Anyone unable to use older everyday stamps by 31 January will be able to exchange them for newer barcoded ones free of charge.
