AT&T Kiosk at Costco in
Riverhead, New York

Welcome to our AT&T Kiosk location at COSTCO! You can find us directly behind the Costco gas station. When you walk into the store, head alongside the orange gate to your right until you reach the main aisle. Take a slight walk straight ahead and you’ll find our kiosk next to the iPhone displays. We look forward to assisting you with all of your AT&T needs!
