The Obamas are in Hawaii for their annual Christmas vacation.
The NORAD program, which began in 1955, attracts millions of visitors to its website from hundreds of countries and territories.
More than 1,200 volunteers staff an operation center that responds to hundreds of thousands of phone calls and emails from around the world.
Mrs. Obama gave callers Santa's latest position on NORAD's map and answered personal questions.
One girl from New Jersey, named Abigail, wanted to know the first lady's favorite Christmas song.
"My favorite Christmas song? That’s a good question, Abby. I like 'Jingle Bells,' because everybody can sing 'Jingle Bells,'" the first lady said. "What’s your favorite song?"
"Silver Bells," Abigail replied.
Google this year launched its own Santa-tracking website.
