Do NOT drop off equipment at:

Lumen/CenturyLink/Quantum Fiber has no consumer retail stores. UPS/FedEx prepaid label only.

How to return CenturyLink / Quantum Fiber equipment (4-step path)

  1. Call CenturyLink / Quantum Fiber first at 1-877-754-6126 and request a return label. This is the fastest way to get the official prepaid shipping label.
  2. Pack the equipment in any box that fits — the original packaging is not required if you go through UPS Store, since they'll pack it for you.
  3. Drop at any UPS Store nationwide with the prepaid label attached. UPS scans it, gives you a tracking receipt — that's your proof of return.
  4. Keep the tracking number for at least 60 days. If CenturyLink / Quantum Fiber ever bills you for the equipment, this is your evidence that it was returned on time.

What you need to return

  • Quantum Fiber router (C5500XK or similar)
  • Fiber ONT (some models)

CenturyLink / Quantum Fiber return deadlines + fees (what to expect)

CenturyLink / Quantum Fiber gives you 30 days from cancellation to return all rented equipment. Miss that and they'll typically bill the full retail price — usually $100–$300 per device. We've seen the bill hit on day 31 more than once. Don't drag it out.

The safe paper trail: drop at UPS Store, get the printed tracking receipt, take a photo of it with your phone. If anything goes sideways with the carrier later, that receipt + tracking number is your evidence the equipment was returned on time.

What CenturyLink / Quantum Fiber considers "rented" vs. "purchased" equipment

You only need to return equipment CenturyLink / Quantum Fiber rented to you. If you bought a retail modem or router (an Arris, Netgear, TP-Link, etc.) it's yours to keep — they'll never ask for it back. If you have a CenturyLink / Quantum Fiber-branded gateway, that's almost certainly rented. Check your bill — the line item "equipment rental" or "gateway fee" tells you which units to return.
