Is the phone paid off? What you can and can't check

Updated November 3, 2026

Many phones in the US are bought on a payment plan. If the original owner sells the phone before it's paid off and then stops paying, the carrier or lender can report or lock it, even though you paid the seller in full. Here's the honest picture.

What an IMEI check can show

  • Whether the phone is on the lost/stolen list today. Unpaid phones can end up there.
  • On Samsung, whether Knox Guard (a lender lock used for financed phones) is on.
  • On iPhone, whether it's locked to a carrier. A lock doesn't prove the phone is unpaid, but it's a reason to ask.

What it can't show

There's no public check that confirms a phone is fully paid off with every carrier. LegitPhone can't confirm it either, and you should be wary of anyone who promises they can. A clean result means nothing was reported on the day you checked.

What to ask the seller for

If a seller can't show any of that, the price should reflect the risk, or you should walk away.

  • Open the carrier's app or account in front of you and show the device balance is zero for this phone.
  • The original receipt, or a payoff confirmation from the carrier.
  • A written receipt from them with the IMEI, the price and their name.
