The Model 3 is the electric carmaker's first affordable mainstream vehicle. It debuts on March 31, with production scheduled to begin in late 2017.
Formal pricing for the Model 3 has not been announced, but it is expected to cost around $35,000, roughly half the cost of the larger 2016 Tesla Model S electric sedan.
The reservation fee in the U.S. is $1,000.
Tesla said the way for buyers "to get a better spot in the queue" is to visit their local Tesla store when it opens on March 31. The second way is to make a reservation online at TeslaMotors.com when the live unveiling starts at 8:30 p.m. PT.
"There will be a different queue for each region," Tesla said.
Deliveries of the Model 3 will begin on the West Coast in North America and then move east, Tesla said.
The staggered deliveries will continue throughout the world, including Europe and Asia.
"We recognize that everyone wants to get their Model 3 as quickly as possible," Tesla said. "Our overarching goal is to maximize total customer happiness within the bounds of what is physically possible."
Edmunds says: Car shoppers get more detailed instructions on how to get their hands on the highly anticipated Tesla Model 3.
