New Royal Mail logo

From 12 July 2024 the Royal Mail logos used across England, Northern Ireland and Wales will be changing to feature the King’s crown, whilst the Royal Mail logos used in Scotland will not change as the crown remains the same.

We will be updating the design of our Printed Postage Impressions (PPI) with the new Royal Mail logos, as well as the PPI generators and guidance documents in the coming months. We are mindful of the challenges some customers may meet in implementing the new PPI design by this date. Therefore, there will be a two-year time period to change to the new PPI design. You can begin using the new designs as early as you wish. We will continue to process your mail with the old PPI design throughout the period while you make the transition to the new PPI specifications.

We will update this page with more information.
