GUIDE
My preschooler wants to write to Santa. How do we get a reply in the mail with a North Pole postmark, and how early do we send it?
By the seenow! teamLast updated:
Use the Postal Service's North Pole postmark program. Your child writes to Santa, you write Santa's reply, and you mail the stamped reply inside a Priority Mail Flat Rate envelope to the postmaster in Anchorage, Alaska, who postmarks it and sends it on. For 2026, USPS recommends mailing it between November 23 and December 1.
Note: This article reflects information available at the time of publication. Programs and services may change, so please check official sources for the latest details.
WHY
Why this happens
When a child asks where to send a letter to Santa, parents usually hear about two different Postal Service programs at once, and they work in opposite ways. The first is the North Pole postmark. You keep your child's letter, write Santa's answer yourself, and mail that answer to a post office in Anchorage, Alaska. The postmaster there stamps the North Pole postmark on it and sends it back into the mail to your child. The reply comes from you, but the envelope carries the postmark your child can check.
The second is USPS Operation Santa. Your child mails a letter to Santa's North Pole address, and the Postal Service may post it online, without personal details, for people to adopt and answer with a gift. That is a lovely program, but USPS says sending a letter does not guarantee it will be posted, adopted, or that a gift will arrive. If the goal is a reply your child is sure to get, the postmark program is the one to plan around.
Timing is the other trap. The postmark program asks you to mail by the start of December, weeks earlier than the general holiday mailing dates many families have in mind.
| Date | What happens |
|---|---|
| September 14 | Operation Santa's mailroom starts accepting letters to Santa |
| November 23 to December 1 | USPS's recommended window to mail your North Pole postmark package to Anchorage |
| After December 1 | USPS recommends Priority Mail Express for the postmark package |
| December 5 | Operation Santa's last call for letter writers |
| December 17 | Recommended send-by date for First-Class Mail to arrive by December 25 in the contiguous U.S. |

HOW TO
What you can do starting today
Have your child write the letter in the second half of NovemberNo app needed
A preschooler can draw a picture and dictate a few lines while you write them down. USPS's instructions say to put the child's letter in an unsealed envelope addressed to Santa Claus, North Pole. Unsealed matters, because you will open it later to read it and answer the details. Let your child put on the stamp or drop it into your hands "for the mail carrier," whichever fits your family.
Write Santa's reply with details only Santa would knowNo app needed
Answer the things your child actually wrote about: the toy they asked for, the new baby brother, learning to ride a scooter. USPS suggests writing a personalized response, either on a separate sheet or on the back of your child's letter, and signing it from Santa. Disguise your handwriting or print it out if your child knows your writing well.
Pack it the way the Anchorage postmaster expectsNo app needed
Put the reply, or both letters, in an envelope addressed to your child, with "Santa Claus, North Pole" as the return address and a Forever stamp. Then place that envelope inside a Priority Mail Flat Rate envelope or box, pay the postage, and address the outer package to: North Pole Postmark, Postmaster, 4141 Postmark Dr, Anchorage, AK 99530-9998. USPS's instructions for holiday cards with the North Pole postmark use the same address, with each card in its own stamped envelope inside one Flat Rate package.
Mail it between November 23 and December 1No app needed
USPS's Postal Bulletin for October 29, 2026, recommends sending between November 23 and December 1, 2026, so the letters reach Anchorage in time to be postmarked and get back into the mail for Christmas. If you miss December 1, USPS recommends Priority Mail Express for the outer package. Hand the package over at a Post Office counter so the postage is right.

If your child also wants to write to Operation Santa, keep it flat and simpleNo app needed
Some kids want their letter to "really go to Santa." Operation Santa's address is Santa, 123 Elf Road, North Pole, 88888, with your full return address in the upper left and a First-Class stamp. Its key dates for 2026 list December 5 as the last call for letter writers. Skip glitter and glued-on decorations, which USPS says can keep a letter from being uploaded. Treat any answer as a bonus, not a promise.

WITH SEENOW!
Doing it with seenow!
seenow! is a private family app where everyone shares a short clip, about 2 seconds a day. It has nothing to do with mailing the letter, but it lets far-away grandparents see the two moments kids remember.
- Film 2 seconds of your child sealing the letter or handing it over at the Post Office, and again when the reply arrives. Grandparents in the family group get a notification when you post.
- The seenow! camera can film with the front and back cameras at once, so one clip shows the envelope and your child's face as they spot the North Pole postmark.
What seenow! can’t do
- seenow! cannot mail letters, track the package, or speed up the postmark. The Postal Service handles all of that.
- You can only post what you film with the seenow! camera, so photos already saved on your phone, like an earlier picture of the letter, cannot be added.
Core features are free.
POINT
Things to watch for in this situation
Check the dates again in late November
The 2026 dates on this page come from USPS's October 29, 2026, Postal Bulletin and the Operation Santa site. USPS can change program details, so look at its Letters from Santa page before you mail.
Keep last names off anything you would not want posted
USPS says letters sent to Operation Santa may be published on its website without personal identifying information. Even so, a first name and a wish list are enough for a letter to Santa. The postmark program is different: your child's letter never leaves your house unless you choose to include it.
Hide the outer envelope
The reply arrives in its own envelope, but the Priority Mail package you send to Anchorage, and its receipt, will give the game away if a curious preschooler finds them.
FAQ
Frequently asked questions
Does the Postal Service write the reply from Santa?
Not in the North Pole postmark program. You write the reply, and USPS adds the North Pole postmark and mails it to your child. Operation Santa is different: letters may be adopted by people who answer with gifts, but USPS says that is not guaranteed.
What if we miss the December 1 date?
USPS recommends Priority Mail Express for the outer package if you miss December 1, 2026. After that, a reply may still arrive, just with less time to spare.
Can grandparents in another state send the reply instead of us?
Yes. Anyone can mail the package to Anchorage, as long as the inner envelope is addressed to your child. Share the details from your child's letter with them first so Santa's answer matches.
