How to check if an iPhone's IMEI is blacklisted or clean
A blacklisted IMEI can stop a phone from working on cellular networks. Here's what blacklisting means and how to check before buying.
An IMEI is blacklisted when it has been reported to carrier and industry databases as lost, stolen, or carrying an unpaid balance. A blacklisted phone may be blocked from connecting to cellular networks — no calls, no texts, no mobile data — even though it powers on and looks perfect. A clean IMEI simply means it hasn't been flagged. This is separate from Activation Lock: a phone can be clean of one and not the other.
Why a phone gets blacklisted
- Reported lost or stolen by the owner or insurer.
- Unpaid bills or financing — a phone still being paid off on a carrier instalment plan can be barred if payments stop.
- Fraud flags raised by a carrier.
Blacklists are regional
Status can differ by country and carrier. A phone that's clean where it was sold may be blacklisted elsewhere, so check against the market where you'll actually use it.
How to check the IMEI
- 1
Get the IMEI
Dial *#06# or open Settings → General → About. (See our guide on finding the IMEI.)
- 2
Run a status check
Put the IMEI through a reputable checker such as 96 Check App, which returns a blacklist / clean status indicator alongside the model and other details.

Cross-check for your region
In the US, the carrier industry's Stolen Phone Checker (stolenphonechecker.org) covers the major networks. Your carrier can also confirm whether an IMEI will activate on its network.
“Clean today” isn't “clean forever”
A phone that's still on an instalment plan can read as clean now and be blacklisted later if the previous owner stops paying. Ask for proof the device is fully paid off and get a receipt with the IMEI on it.
Red flags when buying
- A price that's far below market value.
- A seller who won't share the IMEI or a photo of Settings → About.
- No original receipt or proof of purchase.
- Pressure to complete the sale quickly or off-platform.
A status check takes seconds and can save you from a phone that won't make a single call. Run the IMEI through 96 Check App for a quick reference, verify it for the region you're in, and pair it with the Activation Lock check before you pay.
Key takeaways
- Blacklisted = reported lost/stolen or unpaid; it can block cellular service entirely.
- Blacklist status is regional — check it for where you'll use the phone.
- A clean status now doesn't guarantee it stays clean if the phone is still being financed.
- Treat any checker result as informational reference, then confirm with the carrier.

Frequently asked questions
- Will a blacklisted iPhone still work?
- It will power on and work over Wi-Fi, but it may be blocked from cellular networks — meaning no calls, texts, or mobile data on the carriers that honour the blacklist.
- Is a clean IMEI the same as no Activation Lock?
- No. Blacklist status and Activation Lock are separate. A phone can have a clean IMEI but still be Activation Locked, or vice versa — check both before buying.
- Can a blacklisted IMEI be removed?
- Only the party that reported it (the carrier or original owner) can usually clear a blacklist entry, for example once an unpaid balance is settled. As a buyer, assume a blacklisted phone will stay blacklisted.
