Returning your equipment
Accepted return methods: mail-to-sonic · ups-store-prepaid-label
You must return: Sonic router/Eero (if rented), Fiber ONT, Phone modem (if you had Sonic phone)
⚠ Do NOT drop equipment at these stores
These branded retail stores share the carrier's name but cannot accept equipment returns for this service. Confirm before driving:
- NONE — Sonic has no retail
Common mistake: Sonic encourages customer-owned routers, so most customers don't have anything to return. Confirm what (if anything) you need to send.
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.
