There's a separate program for parents to write their own reply letters from Santa and get them mailed back to their kids with a North Pole postmark. The "Operation Santa" name wasn't formalized ...

Local insurance broker Howden Yeovil has officially opened its North Pole Mail Service, so that children can send a letter to Santa this Christmas and even get a personalised response back.

If you are posting your Santa letters to the Santa's Grotto you will need to add a stamp. If you are hoping to get a response from Santa check out the Royal Mail website for more information.
