Take a look inside Idaho’s largest Amazon facility during the Prime Day rush
During Prime Day sales, the Nampa Amazon Fulfillment Center is in nonstop motion, working in full force to meet the demands of the Treasure Valley.
The Idaho Statesman went inside Idaho’s largest Amazon facility Thursday to see its operations during one of its busiest weeks of the year.
Prime Day, which is more than one day, is Amazon’s yearly sale for paid members on products across its site offering up to 50% off select items. The facility’s general manager, Matt Atkinson, said it takes extensive planning and preparation for the surge in orders for the four days of deals, running from June 23-26 this time around.
“We’ve spent a few months preparing for this, getting the teams ready,” Atkinson said. “The sale started on Tuesday, and now we’re pushing out double the volume delivering for all of our customers here in the Treasure Valley.”
According to Atkinson, the facility was projected to send out up to 4 million items this week, which is about two times the amount of a typical week.
“Boise customers are going to see incredible savings this Prime Day — and it’s all being powered right here,” Atkinson said. “This is a site where people and robotics work together to deliver for customers, and Prime Day is when you really see that operation at full speed.”
The Nampa facility, known to the company as BOI2, serves the Treasure Valley and greater Northwest region. It has roughly 2.5 million square feet across four floors, about 13 miles of conveyance, and between 3,200 and 4,000 employees.
On top of that, the center is one of Amazon’s robotics-equipped facilities. There are more than 9,000 robots that aide workers in picking, packaging and shipping items. The Nampa facility incorporates this Amazon technology to help handle the mass amounts of products going in and out of the center.
An order starts with just a click from a customer, of course, and then it populates at a local facility, where an Amazon employee, possibly with the help of a robot, retrieves the product and sends it on the journey through the facility on the way to your door.
Riding a conveyor belt through the building, the item is taken to the packaging station, where it is placed in an Amazon-branded box or bag before it heads to the shipping station. That’s where it receives labels and is placed with other boxes ready to head to a delivery station.
As Amazon Prime members know quite well, customers are able to get certain products at their door the very same day — sometimes within hours, Atkinson pointed out.
Prime Day deals this year included sales on brands such as YETI, Stanley, Hydro Flask, Beats, Samsung, Lenovo, Dyson and North Face. There are have been a number of small and medium-size independent businesses with products on sale, including some from Idaho. Boise-based business Lovevery, which sells children’s toys, has up to 25% off on products on its Amazon storefront.
According to numbers provided by Amazon, 60% of its sales are from independent seller products, and in 2025, Idaho independent sellers had more than 18 million items purchased on Amazon.
The Nampa fulfillment center was the second building Amazon constructed in the Treasure Valley, and it’s one of three fulfillment centers in Idaho. The company also has three delivery centers and a Whole Foods Market.
As of this year, the company has invested $3 billion in Idaho since 2010, which includes infrastructure and employee compensation, according to a fact sheet it provided at the facility tour. Amazon has said its investment in the state continues to grow with the possibility of drone delivery in Nampa, and the company indicated it is eyeing more Treasure Valley projects.
