. Old UK Royal mail stamps - time running out for the old versions to be converted to Barcoded versions. Photographed on 7 June 2023. The recorded location is Britain , UK. In February 2022 new barcoded definitive design stamps were introduced. The rectangular (matrix) codes, unique to each stamp, use a trademarked coding designed to prevent counterfeiting and to enable tracking of letters, and to enable correspondents to link digital content to their stamps. Until 2022 any 1st and 2nd class and decimal currency postage stamps could be used. old Machin and country definitive design stamps without barcodes are no longer valid from 31st July 2023, with old ones exchangeable for barcoded ones indefinitely through a process which Royal Mail calls the Stamp Swap Out scheme. Special Stamps with pictures and Christmas Stamps without a barcode continued to be valid Stamps are exchanged like-for-like: a 1st class stamp will be replaced by a 1st class one, not 95p. In relation to design history, historical context shows that material culture includes the ordinary products people bought, used, collected or displayed; Small manufactured objects can reveal national identity, advertising, technology and popular taste in ways that formal records do not. For the story of packaging waste, it is useful to note that packaging waste illustrates the practical side of environmental policy; Products combining plastic, foil, paper or food residue can be difficult to process and reveal the limits of systems designed around simpler material streams. The historical setting for collectable is that printed and graphic ephemera are highly effective dating evidence; Tickets, stamps, posters, comics, manuals and vouchers combine wording, typography, colour and branding in forms that are often discarded after use. As of 2026, the position for design history is that online resale, nostalgia and interest in vintage design have made many ordinary twentieth-century objects active.
