Christmas is quickly approaching, which means it's time for your child to write his or her letter to Santa Claus. And with the help of the U.S. Postal Service, your child will even get a response from Santa himself!

The Letters from Santa program is simple. Here's how it works:

Have your child write a letter to Santa and place it in an envelope addressed to: Santa Claus, North Pole.

When you're alone open your child's envelope and write a personalized response. Be sure to sign it "From Santa."

Insert both letters into an envelope and address it to your child.

Add the return address: SANTA, NORTH POLE, to the envelope.

Affix a First-Class Mail stamp to the envelope.

Place the complete envelope into a larger envelope with appropriate postage and address it to:

North Pole Postmark Postmaster

4141 Postmark Drive

Anchorage, AK 99530-9998

Once both letters are sent, Santa's helpers at the post office will take care of the rest.

"Letters from Santa" have to be postmarked by December 15 to reach Santa before Christmas, but USPS recommends sending them by December 8.
