WATCH: An Post to deliver 130,000 Irish letters to Santa this Christmas
Letters to Santa should be sent by Friday if you want a reply
More than 130,000 letters to Santa have been sent this year, with most Irish boys and girls on the 'nice list', according to An Post.
Children all over Ireland have been sending their Christmas wish lists to the North Pole via Dublin's GPO.
For most children, Santa is busy replying and will send a letter back before his worldwide journey later this month.
Getting all the letters ready for Santa takes a lot of time, according to An Post's Communications Executive Eimear Breen.
"Once a child posts a letter, it goes through our system within four hours and then it's all put aside for the elves," she said.
"For the turnaround then, Santa sends all the post back by the last day of posting. They'll be in the system by the 19th."
Some of the letters contain more than paper too, with the elves getting lovely gifts like glitter, soothers and half-eaten sweets.
For those who don't have their lists sent off, it may be a bit too late for a reply, but Santa will still get it in time.
"Santa always tries to reply to all of them, but last dates for posting is obviously very important for the North Pole and for us in An Post," she said.
"it's fantastic. It's usually the first letter for a child to write, so it's very important from that aspect. When they're writing to Santa they put an awful lot of thought into it and this thought process can go on for months before they actually put pen to paper.
Meanwhile, the latest dates for guaranteed delivery of cards and parcels are getting closer. Today is the deadline for parcels and cards to Australia, New Zealand and Asia.
For parcels to the US, it’s December 7th and 13th for cards.
