Royal Mail's Christmas 2025 last posting dates

Royal Mail has issued an urgent seasonal alert to households across the United Kingdom, urging them to prepare their Christmas mail as early as possible to avoid disappointment. The postal service has officially released its final recommended posting dates for 2025, providing a clear schedule to ensure cards, letters, and parcels reach their destinations before the 25th of December.

Critical Christmas Posting Deadlines

The newly published schedule outlines a staggered set of deadlines depending on the service you use. For standard mail, the last chance to send 2nd Class items is Wednesday, December 17, 2025. If you are relying on the faster 1st Class service, you have until Saturday, December 20, 2025 to get your items into the system.

For those sending more time-sensitive or valuable packages, the deadlines are tighter. The final posting date for the popular Royal Mail Tracked 24 service is Sunday, December 21, 2025. If you require the utmost certainty, the last posting date for Special Delivery Guaranteed is Tuesday, December 23, 2025.

Important Dates for Returns and Parcelforce Services

The advisory also includes key information for returns and other courier services. If you are expecting a return parcel via Royal Mail Tracked Returns 48 to come back to you before Christmas, it must be posted by Friday, December 19, 2025. This same date is also the final deadline for the Express48 service from Parcelforce Worldwide for UK inland deliveries.

For other Parcelforce options, including Express10, ExpressPM, and Express24, the last posting date is Monday, December 22, 2025.

Act Early and Enter a Magical Competition

In its official statement, Royal Mail strongly advised customers to "allow plenty of time for posting this Christmas" and to "post items and gifts early." The company also included a crucial disclaimer, noting that while these dates are correct at the time of publication, they are "subject to change," reinforcing the need for prompt action.

Adding a sprinkle of festive cheer, Royal Mail announced a competition where participants could win a share of over £500,000. To enter, you need to write the word 'Magical' on your Christmas card envelope, use a Royal Mail Christmas 2025 stamp, and follow the entry instructions.

With the festive season fast approaching, acting on these dates is essential for ensuring your Christmas wishes arrive on time.
