Employees identify these buildings as IL1 through IL6. The inside of 1 Infinite Loop is restricted to employees and persons outside of Apple must be accompanied by employees. A large car park is located outside of 1 Infinite Loop.

4 Infinite Loop (IL4) houses the Town Hall conference center, which hosted early Apple Special Events.

Infinite Loop also housed The Company Store, the corporate store where customers could purchase Apple-branded merchandise; employees got a discount. In 2015, it was renovated and reopened as "Apple Infinite Loop" to present the full Apple retail store experience and now also sells the Mac and iOS lines. This store remains the only place within the campus that is open to the public.
