Santa is on his way around the world to deliver gifts, and once again you can track his progress throughout Christmas Eve.

The North American Aerospace Defense Command (NORAD) and Google both offrer live tools to track Santa in the U.S and Canada. You can check in on the Detroit Free Press’ YouTube channel as well.

The U.S. Department of Agriculture also issued Santa and his “eight tiny reindeer” a transit permit that will “allow reindeer to enter and exit the U.S.” between 6 p.m. on Dec. 24 and 6 a.m. on Dec. 25, local time, through or over any U.S. border or port of entry.

NORAD’s long history tracking Santa was born from a mistake in 1955. According to legend, an ad in a Colorado Springs newspaper invited children to call Santa, but inadvertently listed the phone number for the Continental Air Defense Command, NORAD’s predecessor, which was based in Colorado Springs.

Despite the mistake, officers at the base played along. Since then, NORAD Tracks Santa has gone global, receiving calls from around the world and posting updates on social media for millions of fans, and updating its website following Santa’s progress on Christmas Eve.

The map tracking Santa will begin Dec. 24, Christmas Eve from NORAD, a joint U.S.-Canada command responsible for protecting the skies over both nations.

The Detroit Free Press will livestream Santa’s journey starting at 9 a.m. Tuesday. You can watch below:

Trackers worldwide can also call 877-HI-NORAD (877-446-6723) on Dec. 24 to ask live operators about Santa’s location from 6 a.m. to midnight MST.

Hundreds of Canadian and American military personnel and civilians volunteer keep up with Santa. You can visit their website to keep up with Santa, or you can call a volunteer at Peterson Space Force Base in Colorado.
