Returning your equipment
Accepted return methods: mail-to-carrier-hq · ups-store-prepaid-label
You must return: Carrier-rented gateway/router/ONT, Set-top boxes (if any), Remotes
Common mistake: Call the carrier first to get a prepaid label, then drop the equipment at any UPS Store with the label. Keep the tracking receipt — UPS dropoff is the safest paper trail.
Where you can actually go in person
Confirmed company-operated stores that can sign up service AND accept equipment returns. Authorized-retailer addresses are tagged separately because they cannot always handle returns.

Any UPS Store nationally — Comporium prepaid label UPS Store partner
Any UPS Store, (nationwide), — —
Accepts equipment: Carrier-rented equipment
Branded as: The UPS Store (independent franchise)
Bring the carrier-issued prepaid label and the equipment in original packaging if you still have it.
