Key facts
- Eligible occasions: 100th and 105th birthdays and every year after that, plus Diamond (60th), 65th, and Platinum (70th) wedding anniversaries and every year after — younger milestones aren't covered by this office.
- The recipient must be a current citizen of one of The King's realms or a UK Overseas Territory — those living overseas need to include proof of British nationality (a photocopy of a current passport).
- Postal applications aren't accepted any sooner than 3 weeks before the date (a 2-week extension applies around Christmas and Easter); belated messages can still be arranged up to 6 months after the event.
- Include a photocopy of the birth or marriage certificate if you can — if the celebrant is a UK resident on the State Pension, the office can instead verify a birthday directly with the Department for Work and Pensions.
- Canada, Australia, and New Zealand residents apply through their own Governor-General's office, not this address — see PostPal's Canada greetings page if that's you.
How to send your letter
- 1
Confirm the milestone qualifies
This office only covers 100th-and-later birthdays and Diamond Wedding (60th) anniversaries and later. For anything younger, there isn't an official Royal message to request.
- 2
Gather your documents
Photocopy the celebrant's birth certificate (for a birthday) or marriage certificate (for an anniversary). If a birthday celebrant is a UK resident receiving the State Pension, you can skip this and the office will verify with the DWP instead — allow up to a week extra for that route.
- 3
Time your application
Post your form no earlier than 3 weeks before the date. Applying too early means the office will simply hold it — there's no benefit to sending it further ahead.
- 4
Post it, or send it through PostPal
Address the envelope to Anniversaries Office, Buckingham Palace, London SW1A 1AA — or upload your completed form and any certificate photocopies to PostPal, and we'll print, envelope, and post them the next business day for £4 flat, with a dated confirmation emailed to you.
Common questions
Where do I send a 100th birthday message application for The King?
Post it to the Anniversaries Office, Buckingham Palace, London SW1A 1AA. This is the office that arranges Royal congratulatory messages for 100th birthdays and later.
Does The King send messages for wedding anniversaries?
Yes — for Diamond (60th), 65th, and Platinum (70th) wedding anniversaries, and every year after the 70th. Anniversaries under 60 years are not covered.
How early can I post my application?
No earlier than 3 weeks before the celebration (with a 2-week allowance around Christmas and Easter). If the date has already passed, you can still apply for a belated message up to 6 months after the event.
What if I can't find the birth or marriage certificate?
For a birthday, if the celebrant is a UK resident on the State Pension, the Anniversaries Office can verify their age directly with the Department for Work and Pensions instead of a certificate — expect up to a week longer for confirmation. For an anniversary, the relevant General Register Office can search and confirm the marriage details on your behalf.
I live in Canada, Australia, or New Zealand — do I use this address?
No. Buckingham Palace directs residents of Canada, Australia, and New Zealand to apply through their own Governor-General's office rather than mailing London directly.
Can PostPal post my application to the Anniversaries Office?
Yes. Upload your completed form and any certificate photocopies as a PDF, and PostPal prints them, seals them in an envelope, and posts them the next business day for £4 flat, with a dated confirmation emailed to you.
