Kids send their letter to Santa in various ways: some stick it to their bedroom window, others leave it by the fire for one of the elves to collect while others pop it in the postbox.
And if your little one is planning on sending it via Royal Mail they will need to be quick if they want a response from the man himself - because the deadline is Friday, 8th December.
We have joined forces with former postman @scottmannmp, MP for North Cornwall and former @Parcelforce driver @hughgaffneymp, MP for Coatbridge, Chryston and Bellshill, to remind children of the deadline for ‘Letters to Santa’ - https://t.co/YoYhqixmjU pic.twitter.com/t3H06kLOrB— Royal Mail (@RoyalMail) December 1, 2017
Every year, hundreds of thousands of letters are sent to Santa's Grotto by kids in the UK, with many then anxiously awaiting his reply.
And thanks to a large team of elves, Santa has managed to send an update on how his preparations are going for the past 50 years!
So, what do parents need to do to make sure Santa will reply?
Simply include your child's full name and return address on the letter and send it to:
Santa/Father Christmas, Santa’s Grotto, Reindeerland XM4 5HQ.
