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.

Does Sonic serve your address?

Use our ZIP-coverage tool to confirm availability — we cross-reference live FCC Form 477 data with the carrier's own footprint map.
