Amazon Locker - Neci in Chula Vista is a self-service package pickup and return station housed inside the 7-Eleven at 899 Third Avenue in the southern stretch of the Third Avenue corridor. The locker accepts deliveries from Amazon's logistics network for customers who need a secure drop point rather than doorstep delivery, serving the same Third Avenue commercial zone where Yellow Letter HQ processes high-volume direct-mail shipments. Customers receive a unique six-digit pickup code via email or the Amazon app, then retrieve packages within three calendar days before unclaimed items are returned to the fulfillment center. Secure locker delivery eliminates porch-theft risk for residents in multi-unit housing developments, a concern shared by the dense apartment communities managed by Gateway Chula Vista across the surrounding 91911 zip code. The Neci unit processes both forward deliveries and prepaid return shipments through Amazon's reverse-logistics QR-code scanning system, with compartments sized from small-parcel slots to mid-size bays across the multi-door locker bank.
