Used as an identifier, the IMEI code is unique to each cell phone; understand how it works and learn how it can be useful
The IMEI code stands for International Mobile Equipment Identity. It is a unique, global numeric code found on devices that connect to cellular networks, such as smartphones, tablets, and 4G or 5G modems. Using an analogy with automobiles, the IMEI is equivalent to a car’s chassis number and is used as an ID.
What is the IMEI for?
The IMEI serves as a “fingerprint” for cell phones, and allows operators to identify devices connected to their mobile phone network.
Although it is used by mobile operators, the IMEI is a code associated with the mobile device , not the chip. SIM cards have their own serial number, called ICCID.
Even though it is a unique code and used as a serial number by operators, the IMEI is different from the serial number assigned by cell phone manufacturers . Therefore, each company uses its own number to identify its devices for control and warranty purposes.
What can you find out with your cell phone’s IMEI?
The IMEI is a code for identifying devices and carries information such as the device manufacturer and the mobile device model. Apart from that, the code does not reveal any other information to ordinary users.
It is not possible to identify the owner of a cell phone just by the IMEI, for example, but it is possible to check the code in the Anatel database and see if it is registered as an irregular device. This action can be an extra layer of security when buying a second-hand device or from an unknown store.
Finding a Cell Phone’s IMEI
You can find out a cell phone’s IMEI by dialing the traditional code *#06# , but the number can also be found on the device’s invoice, on the product’s original box, and even with your Google account, in the Find My Device app. iPhone owners can also use the “Devices” section of their Apple ID.
Can a cell phone have two IMEI numbers?
Your cell phone can have two IMEI numbers when it supports two simultaneous lines, either with two slots for two chips or through the virtual eSIM chip .
To know which IMEI to use, pay attention to the chip slot: IMEI 1 is usually assigned to SIM 1, while IMEI 2 is generally used by SIM 2 or eSIM.
If you want to block the IMEI of a dual SIM device, be sure to block both serial numbers. Otherwise, the device will continue to work partially.
Is it possible to change the IMEI of a cell phone?
The IMEI is considered a serial number and, as such, should not be changed by the owner. Only the manufacturer of a smartphone and its authorized technical support services can legitimately change the IMEI of a cell phone, especially if there has been any repairs to the main board.
Some technicians and apps can change a cell phone’s IMEI number, but this practice is illegal because it violates a serial number. Therefore, it is not recommended to perform this procedure, as carriers can identify the tampering and block the device.
Can two cell phones have the same IMEI code?
Theoretically, the IMEI is a unique identification code for each cell phone. However, it is possible for more than one device to have the same code — this is the case with cloned or pirated cell phones, which do not receive certification from agencies such as Anatel and can disrupt the functioning of mobile networks.
Through the Celular Legal project, Anatel combats the use of irregular, pirated, cloned devices and devices without certification accepted by Brazil. These devices are blocked and prevented from receiving a signal from mobile operators.
Checking a Cell Phone’s IMEI Status
If there is an IMEI block, the cell phone is prevented from establishing a network connection with mobile operators, making it impossible to make calls, exchange SMS and use the mobile internet.
Find out how to check a cell phone’s IMEI in Anatel’s database, and check if there are any impediments associated with a device.
*#06# is the universal code to find out the IMEI of a cell phone
Blocking a cell phone’s IMEI
Blocking your cell phone’s IMEI is essential in cases of theft or loss of the device. This restriction prevents the smartphone from connecting to mobile operator networks and discourages the use of products without proper origin.
Who can block a cell phone’s IMEI?
IMEI blocking can be requested by the owner of the mobile line. The procedure can be requested directly from the operator, or, in some states, from the Civil Police.
What happens when a cell phone is blocked by IMEI?
By blocking the IMEI, the cell phone is unable to connect to the mobile operator networks. Therefore, the smartphone has no signal and cannot be used to make calls, exchange SMS or use mobile internet.
However, blocking the IMEI does not prevent the device from continuing to function for other purposes, including accessing the internet via Wi-Fi. Was your phone stolen? See what else you can do to protect your data .

Can I track a cell phone by IMEI?
The IMEI is just a device identification code, and therefore cannot be used by ordinary people to track a cell phone, regardless of whether the device is connected to a mobile network or Wi-Fi.
Only mobile operators can check the approximate location of a mobile phone via IMEI, as long as it is connected to their network. However, this information cannot be easily accessed; telecoms only release this data upon request from a court.
It is worth remembering that it is possible to locate a smartphone through platforms such as Find My iPhone (Apple) and Find My Device (Google) . See other alternatives and learn how to track a stolen cell phone .
What does IMEI null mean?
The IMEI null message means that the IMEI code is zero and it is impossible to connect to a cellular network. This can happen due to a hardware failure or incorrect manipulation of system files.
In cases like this, when there are problems with the identification code, it is recommended to seek technical assistance authorized by your cell phone manufacturer.
