The super-secretive process as Amazon narrows the field for a planned second headquarters — and the estimated 50,000 jobs it would create over 15 years — touched down in the Triangle last week, sources tell WRAL News.

Although much secrecy surrounds the vetting of candidate cities, Amazon said last month that visits were planned to each of 20 top locations.

The Triangle is among the 20 finalists for HQ2, but it is unclear whether Amazon is considering one or more of the seven bids submitted from municipalities and groups across the region. After listing “Raleigh” as a finalist in the original list in January, Amazon clarified that the entire Triangle was where the tech giant was looking.

Amazon would not comment Tuesday, and neither would the state’s Department of Commerce.

“We talk to a lot of companies,” Commerce spokesman David Rhoades said. “Until those projects are announced we do not talk about them.”

An Amazon spokesperson said the company is “excited to visit each location,” but would not confirm specifics.

“Amazon is working with each HQ2 candidate city to dive deeper on their proposals and share additional information about the company’s plans,” the spokesperson said in an email.

Others on the list include the usual major tech hubs of Austin, Boston and New York. Other contenders include Chicago, Indianapolis and Columbus, Ohio, in the Midwest.

Los Angeles was the only West Coast city on the list. In the South, Miami and Atlanta joined Raleigh and Nashville on the list.
