Santa address royal.mail
A festive question!
According to Royal Mail, the address for Santa Claus is:
Santa Claus North Pole FX6 6XJ
This special address is used by Royal Mail to handle letters and cards sent to Santa Claus. They even have a special team of elves (okay, postal workers) who sort and respond to these letters.
If you're sending a letter to Santa, make sure to include a return address so that Santa can write back to you. And don't forget to include a stamp!
Remember, the North Pole is a very busy place, so it's best to send your letter early to ensure it arrives in time for Santa to read it.
