Writing to Santa
Father Christmas has asked all good boys and girls to write their letters and post them to him at the North Pole by Friday 8 December.
His elves at Royal Mail and Parcel Force will help deal with the thousands of letters heading Santa's way over the next six weeks - a special tradition which is now in its 54th year.
To make sure your letter reaches him in time, pop it in a stamped envelope by Friday 8 December and send to:
Replies from Santa
Don't forget to include your full name and address when telling Santa what you would like under the Christmas tree as, every year, some lucky children get a reply to their letter.
As Santa and his helpers are busy getting all the presents ready for Christmas Eve, not every letter can get a response, but he always does his best to fit in as many as possible.
Remember - don't forget to include a stamp on your envelope, and your own name and address with your letter, so Santa knows how to get in touch with you!
Top requests to Santa
Over the years, Santa has received lots of requests for toys, games and gadgets, as well as some more unusual presents.
Special requests include sending gifts to charities and hospitals, providing food for the homeless and even moving Christmas to a different day altogether so family and friends can celebrate the season together.
Father Christmas also receives lots of gifts along with his letters, including mince pies, sweets and carrots for Rudolph and the other reindeers.
Christmas posting dates
Mums and dads can sort out their own Christmas mail too by remembering to send any cards or parcels at their local post office before the last recommended dates for U.K. or international postage to make sure they arrive in time for 25 December.
Just like your letter to Santa, it pays to post early, as Christmas is the busiest time of year for Royal Mail/Parcelforce and its staff.
The last dates for U.K. posting are Wednesday 20 December for letters and parcels sent second class and Thursday 21 December for first class services. International postage dates vary, with full details available from www.postoffice.co.uk/Christmas
Christmas stamps are also now available to purchase online and at post office branches nationwide.
