"Apple also directly employs 90,000 employees in all 50 states, putting the company on track to create 20,000 new jobs across the US by 2023," said the company.
Earlier this year in San Diego, Apple announced an expansion that will include 1,200 direct jobs and a new campus featuring hundreds of thousands of square feet of office, lab and research space.
"In Seattle, Apple will add 2,000 new employees in highly skilled engineering positions," it added.
In 2018, Apple spent a total of $60 billion with its suppliers in the US.
Apple highlighted Maccor, one of the 9,000 suppliers, and one which makes battery testing systems.
"The relationship with Apple has been tremendous and company-changing for us," said Maccor President Andy MacKay.
"Apple is a company where quality is paramount and they push us constantly to see if we can make improvements in our commercial product."
