How to Check an IMEI Number (Complete Guide)
Learn how to find, verify, and understand an IMEI before buying, selling, or using a phone on a mobile network.
What is an IMEI number?
The IMEI, or International Mobile Equipment Identity, is a unique number assigned to a mobile phone. It works like a device identifier that carriers and service providers can use to recognize the phone on a network.
This number matters most when you are buying, selling, or verifying a used phone. A quick IMEI check can help reveal whether the device is blacklisted, tied to a carrier, or inconsistent with the seller’s description.
Why checking IMEI is important
Many used-phone problems are invisible at first. A phone can look excellent, turn on normally, and still have serious restrictions that only appear when you try to activate it. That is why running an IMEI check before paying is one of the smartest steps a buyer can take.
- Detect blacklisted or blocked phones
- Check carrier-related restrictions
- Confirm the device matches the listing
- Reduce the risk of scams when buying online
What information will you get?
- Blacklist status and related risk signals
- Carrier-related status when available
- Basic model and device identification details
- Useful information for comparing the phone to the listing

How to find your IMEI
The fastest method is to dial *#06# on the phone. In most cases, the IMEI will appear instantly on screen.
You can also find it in the device settings, on the original box, or in account information associated with the phone. Most IMEI numbers are 15 digits long.
How to check IMEI step by step
Step 1
Find the IMEI number using *#06#, device settings, or the box.
Step 2
Enter the IMEI into a trusted checker tool.
Step 3
Review blacklist status, carrier-related information, and device details.
Step 4
Compare the result with the seller’s listing before sending payment.
Understanding IMEI results
Clean
The device does not appear blacklisted and may be suitable for normal use, depending on carrier compatibility.
Blacklisted
The phone may have been reported lost, stolen, or blocked for carrier-related reasons.
Locked
The phone may be restricted to a specific carrier even if it is otherwise functional.
Common mistakes when buying used phones
- Skipping the IMEI check before payment
- Trusting photos without verifying device status
- Ignoring carrier restrictions
- Buying from unknown sellers without comparing details
Important limitations
An IMEI check is designed to provide information, not to change the device. It cannot unlock a phone, remove blacklist status, or repair hardware or software problems.
Think of it as a risk-reduction step. It helps you make a more informed decision, especially when buying a used phone from a private seller.
Practical tip:
If you are buying a phone in person, compare the IMEI shown on the device to the IMEI in the listing before handing over money.
