Phone blacklist check – Is the IMEI clean or blacklisted?
Are you planning to buy a used phone, or have you already bought one but cannot make calls or send SMS? Or has the device been lost or stolen? In such cases it is essential to check whether the device’s IMEI number appears on a blacklist.
The Fixity blacklist check lets you quickly determine whether your phone is Clean or Blacklisted. This check is especially recommended before buying or reselling a used device.
What does it mean if a phone is blacklisted?
A blacklist is a collection of IMEI numbers reported by mobile operators as lost, stolen, or blocked due to unpaid contracts. If a device’s IMEI is on this list, it is very likely unusable on local networks, or possibly unusable with any operator.
When should you perform a blacklist check?
- Before buying a used phone
- If the device will not connect to a network
- If you cannot make calls or send SMS
- To check a lost or stolen device
- Before selling, to reassure the buyer
What results can you get?
The IMEI check can show two basic statuses:
- Clean – the IMEI is not on a blacklist
- Blacklisted – the IMEI is blocked by operators
The reason for a blacklist status can include theft, loss, or unpaid installment debts.
How reliable is the IMEI blacklist check?
Operators generally share blacklist data with each other, so a blacklisted device often becomes globally unusable. It is rare that a newly reported IMEI is not yet present in the databases, but such cases are very uncommon.
How to check a phone’s blacklist status?
- Prepare the device’s IMEI number.
- Enter the IMEI into the check field.
- Start the check.
- See whether the device is Clean or Blacklisted.
Fixity tip: Always ask for the IMEI before buying a used phone and perform the blacklist check — this helps you avoid purchasing a device that cannot be used on a network.
Note: blacklist data may vary by country and operator; results are based on the currently available databases.
