Yes, Virginia, there is a Santa Claus.

And the U.S. Postal Service can help you prove it in the form of a letter from The Big Guy -- complete with a North Pole postmark. Of course, you're the one who'll write the actual letter, but they don't pay any attention to your penmanship so they won't suspect a thing.

Here's how to keep your little one's belief that there really is a Santa alive via the postal service's Letters From Santa program:

1. Have him or her write a letter/wish list to Santa.

2. Place it in an envelope and have your child address it to "Santa Claus, North Pole."

3. Later, when alone, open the envelope and write a personalized response.

Tip: The postal service suggests you make the response as personal as possible by highlighting your child’s accomplishments over the past year. For example, helping around the house, or receiving good grades in school. It'll help with the authenticity, and the whole he-knows-when-you've-been-good-or-bad threat that we parents like to lord over them this time of the year. You can look over a few sample response letters for guidance HERE.

4. Place both your response letter and your child's letter into an envelope and address it to your child with the return address, "Santa, North Pole" on the envelope.

5. Place a First-Class Mail stamp on the response letter envelope.

6. Place the complete envelope into a larger envelope or Priority Mail Flat Rate Envelope with appropriate postage, and address it to:

North Pole Postmark
Postmaster
4141 Postmark Drive
Anchorage, AK 99530-9998

Provided your letter is mailed off no later than December 8, 2018, the Post Office will take care of the rest, and your child will receive a letter with a North Pole postmark. So get going before you run out of time.

Now, if you'll excuse me. I have some letter writing to do.
