Q&A: Invitations: Addressing One to the White House?
I have heard there is an address where I can send the President a wedding invitation. Do you know what it is?
Here's what you're looking for:
The President & First Lady
The White House
Greetings Office, Room 39
1600 Pennsylvania Avenue NW
Washington, DC 20502
You will receive a pre-printed card with the signatures of the President and First Lady -- which makes a wonderful keepsake.
