Each year, thousands of birthday and wedding anniversary cards are sent to people celebrating significant birthdays and wedding anniversaries.

The delivery of these messages is arranged by the Anniversaries Office at Buckingham Palace, continuing a tradition which goes back to 1917.

Cards are sent to those celebrating their 100th and 105th birthday and every year thereafter, and to those celebrating their diamond wedding (60th), 65th, 70th wedding anniversaries and every year thereafter.

Who is eligible for 100th birthday cards and how do I apply?
