Simple to find if you Lost Your Mobile

An IMEI number-The International Mobile Equipment Identity (IMEI) number is an international identity number used to uniquely identify a mobile phone. The 15-digit IMEI number is an electronic fingerprint transmitted every time a phone is used, which reveals the identity of the mobile handset.

How can I find out my IMEI number? IMEI numbers are independent of the phone number and are usually written underneath the battery or on the back of the handset.. Mobile phone users can also check their 15 digit IMEI number by dialing *#06# on their mobile handset. Mobile phone owners should make a note of their IMEI number and keep the details in a safe place.

If you lost your mobile, send an e-mail to cop@vsnl.net with the following info.

Your name:
Phone model:
Last used No.:
E-mail for communication:
Missed date:

"No need to go to police station"
After reading this, please preserve the IMEI number in a notepad!

How to Find the IMEI Number in my Mobile Phone

Having your cell phone or tablet stolen is not just a bad day at the zoo, it potentially compromises your safety and security. Thanks to the FCC (back in the age of the dinosaurs, the early '80s), ESNs were created to give a unique identifiers to mobile devices. Since then, usage of mobile devices has exploded, and the ESN of yore became the IMEI (International Mobile Equipment Identity) and the MEID (Mobile Equipment ID—a superset of IMEI) of today.

If a phone, iPad, or other mobile device is stolen, carriers in some countries can blacklist the IMEI or MEID so that the thief cannot use the phone in any capacity (regardless of whether or not the SIM card has been replaced). This is a number you should keep on file, in a secure place, should the need ever arise. We'll show you a few tips on how to do this.

Keypad Method

  1. Dial it in. Most phones have a very simple key-in method to retrieve IMEI/MEID numbers: enter a 5-digit string—*#06#—and the number will be displayed on your phone.
    • This is not true for all carriers or phones. For example, while an iPhone on the AT&T network will return the MEID number, an iPhone on the Verizon network dials the number and reaches a recording that says, "Your call cannot be completed as dialed." Good thing there are other methods!
  2.  Go to the dial screen on your phone. On the keypad, enter *#06# without any spaces.
  3. Copy your IMEI. The IMEI will appear as you dial the final character, and should call the information automatically without your having to hit dial or send. 
    • Consider adding *#06# as a phone contact. That way you don’t have to look it up again!

The Battery Method

  1. Turn the phone completely off. As with any electronic device, it's always best to power down before you start poking around the innards. It's doubtful the phone will give you a jolt, but you could fritz out phone easily, and then what good would there be in having your IMEI? 
  2. Remove the back cover. Slide the back open carefully, and remove the battery.
  3. Find the IMEI. Look in the empty battery slot for a white label noting the IMEI. It should be 15 or 17 digits, not including a few forward slashes, and shouldn’t contain any letters. Only the first 15 digits are needed.

iPhone and iPad

  1. Tap Settings. This will open up the Settings window where you can set and see all your preferences.
  2. Scroll down to General, and tap that. You will be shown a list of all the basic information about your pad or tablet. Tap the About field
  3. Locate your MEID. Scroll down the information list that tells you about your songs, videos, photos, etc. Towards the bottom, you will see MEID and to the right of that, a 14-digit number. This is your MEID.
  4. Look on iTunes. Connect your iPhone to your computer, and launch iTunes.
  5. Locate your phone. It will be listed on the left-hand column, under the heading Devices. At the top you will see a picture of your phone, along with your name, capacity, software version, serial number, and phone number.
  6. Click on your phone number. When you click on your phone number in iTunes, it will toggle between your number and your MEID.


  1. Use the dial method. From the phone keypad, enter *#06#, and your IMEI will be displayed.
  2. Look under the battery. Like all phones with an accessible battery, the IMEI is located on a label underneath.
  3. Look in settings. From the home screen, press Menu, then Settings, then About phone, and then Status. Your IMEI (or IMSI) will be located on the resulting screen.

Motorola iDen Units

  1. Turn on your phone. Power up your phone and go to the dialing screen. Press the following key sequence in rapid succession: # * [menu] [right arrow]. Try not to pause or linger.
  2. Locate your IMEI. On units with SIM cards, scroll down until you see IMEI/SIM ID and select Enter. From here you can view your IMEI, SIM, and on some units, your MSN. The first fourteen digits are displayed; the fifteenth is always a 0.
    • On older units without SIM cards:
    • Continue to hit the [right arrow] key until you see IMEI [0] on the display. The first seven digits are displayed.
    • Hit the menu key and then the "soft key" under "next" to display the next seven digits. The fifteenth and final digit is most often a 0.

Lost or Stolen Phone

  1. Locate the original packaging for your mobile device. Don’t worry about the booklet; look for the box.
  2. Locate the barcoded label stuck to your box. It might have been placed over the opening to act as a seal.
  3. Look for the IMEI. It should be clearly labeled and is usually listed together with the barcode and serial number.

What effect does a listing of an IEMI number with an EIR have?

What is an IMEI number?

The GSM MoU's IMEI (International Mobile Equipment Identity) numbering system is a 15 digit unqiue code that is used to identify the GSM/DCS/PCS phone to a GSM/DCS/PCS network.

When a phone is switched on, this unique IMEI number is transmitted and checked against a database of blacklisted or greylisted phones in the network's EIR (Equipment ID Register).

This EIR determines whether the phone can log onto the network to make and receive calls.

How to display a phone's IMEI number:

  • Type *#06# on the keypad. This code works on most phones.

What effect does a listing of an IEMI number with an EIR have?

If the EIR and IMEI numbers match, the networks can do a number of things. They can for example greylist or blacklist a phone:
  • Greylisting will allow the phone to be used, but it can be tracked to see who has it (via the SIM info).
  • Blacklisting bars the phone from being used on any network where there is an EIR match.

IEMI Example:


Type Approval Code (TAC)
The first two digits is the code for the country apporval.

10 - Final Assembly Code (FAC)

07 , 40
10, 20
40, 41, 44
Option International

083781 -  Phone Serial Number
0 -  Additional Number

IMEI Allocation

On-Line IMEI Application Form
Applications for IMEI allocations are made on-line. You must register your organisation before you can apply for an IMEI allocation. Following registration, you will be allocated a manufacturer's Organisation Code; this code must be remembered for use in subsequent IMEI applications.
If you have already received notification of your Organisation Code you do not have to register again.

Equipment Type Approval
Please note that IMEI allocation is not equipment approval. An IMEI allocation does not mean that the equipment has been approved. IMEI ranges are allocated on request; evidence of compliance is not required for an IMEI allocation.

IMEI Number Structure
TAC - Type Allocation Code
Serial Number
Check Digit
Reporting Body Identifier, eg BABT
Type Identifier defined by BABT
Number range allocated by BABT but assigned to individual mobile stations by the manufacturer.
Defined as a function of all other digits (calculated by the manufacturer).

Roles and Responsibilities

GSM Association
The GSM Association (GSMA) has accepted the role of the Global Decimal Administrator (GDA) as recommended by the Joint Experts Meeting on IMEI / MEID, to allocate International Mobile Equipment Identity Numbers (IMEI) to manufacturers for use in GSM , UMTS and multi-mode mobile stations (MS) including these technologies. The ownership and management of the IMEI structure is understood to be invested in the GSM and UMTS industry as a whole and not the province of any one sector. The GSMA has appointed BABT as their agent to carry out IMEI allocations.
The allocation procedure is funded by fees charged for IMEI allocations. Details of the fees are provided during the application procedure.

Operators and Regulators can have access to IMEI allocation information via the GSMA IMEI Database and by Summary report (if requested) under a Non Disclosure Agreement. No other bodies apart from companies jointly approved by the GSMA and EICTA-CCIG will be able to have access to this information.

GSM Manufacturers
Manufacturers must register with the GSM Association before applying for an IMEI allocation. The on-line registration form requests detailed information be provided about the manufacturer. An IMEI allocation will not be provided unless all mandatory fields (*) in the on-line form are completed to support the application.

Only Manufacturers or their authorised representative, covered under the following definition, are eligible to obtain IMEI block allocations. A letter of authorisation for such representatives should be provided to BABT prior to the application.
Manufacturer: A manufacturer is defined as the legal entity that is responsible for designing and/or manufacturing a mobile terminal complying with the standards of GSM or IMT2000 with a view to placing it on the market on his own behalf. The manufacturer has an obligation to ensure that the product intended to be placed on the market is designed and manufactured, and its conformity assessed, to comply with the provisions of the applicable regulations. The manufacturer must retain the overall control of the production of the device and maintain the necessary level of competence to take the responsibility for placing the product on the market regardless of the extent to which aspects of the manufacturing process have been undertaken by third parties.

BABT will assess the application and allocate the organisation with a manufacturer's Organisation Code. This code must be remembered for use in subsequent IMEI applications.
BABT reserves the right to refuse applications where there is a doubt as to the validity of the applicant. A refused application may be re-submitted with additional evidence of validity.

IMEI Database
Every GSM, and UMTS MS or Multi-Mode MS containing these technologies, is required to have a unique identity, known as the International Mobile Equipment Identity Number (IMEI). BABT allocates the IMEI and maintains the IMEI Database records on behalf of the GSM Association.

The IMEI uniquely identifies an individual mobile station and thereby provides a means for controlling access to GSM networks based on mobile station types or individual units. This database is used to populate the Central Equipment Identity Register (CEIR) which is used by GSM network operators.

Applications for IMEI Blocks
You must register your organsiation before you can apply for an IMEI allocation. Following registration, you will be allocated a manufacturer's Organisation Code; this code must be remembered for use in subsequent IMEI applications. A manufacturer seeking an allocation of a block of IMEI should submit a completed copy of the on-line forms.
Manufacturers must comply with the relevant regulatory requirements in their target markets but this is not a pre-condition for allocating IMEI's.

Brandname and Cosmetic Variation
Brand Name and Cosmetic variants of terminal apparatus manufactured by the same production facility may share a common IMEI block whereby the manufacturer maintains full quality control of the IMEI integrity.

IMEI Implementation
The ETSI GSM specifications require that every MS has a unique IMEI. The IMEI is used for security purposes as part of anti-theft measures and as a means of identifying individual or types of mobile stations, which may cause technical problems with the mobile network.

The manufacturer must factory set the IMEI number in the permanent memory of the MS and it must be tamper resistant. In practice, this means that the IMEI should not be capable of being changed outside the place of manufacture. When applying for IMEI allocation the IMEI implementation in a mobile station shall comply with state of the art standards, e.g. 3GPP TS 22.016 and its equivalents.

The MS may be marked externally with the IMEI. However, the manufacturer must ensure that it is the same as the IMEI stored within the equipment and that no duplication of an IMEI is possible.

Test IMEIs
BABT allocates Test IMEIs to allow manufacturers to test prototype mobiles live on a network without previously having obtained regulatory approval (i.e. the mobiles are fully under the control of the manufacturer). They may be single prototype units or a limited pre-production run (for example, the manufacturer may wish to demonstrate a mobile at an exhibition or do some field trials).

The Test IMEI allocation does not grant permission to connect to a network or imply approval for test mobile stations. The use of a test IMEI is subject to any applicable national legislation and regulatory requirements. Operators are under no obligation to allow the use of test IMEI on their networks. A manufacturer will normally need to seek permission from the network operator to use the Test IMEIs on their network. Items with Test IMEI cannot be supplied to the market.
Test IMEIs must not be used for samples given to operators for final product acceptance.

A Test IMEI allocation is 1 million Test IMEI numbers. The number identifies the manufacturer and not the equipment type. It is the manufacturer’s responsibility to allocate Test IMEI blocks to mobile equipment types and manage the use of the numbers so that they can be re-used. BABT are not involved in the assignment of test IMEI blocks to individual mobile equipment types. The manufacturer should allocate the Test IMEIs to prototype models in blocks of 1,000 and maintain their allocation records.

Once testing is complete the old test products must be destroyed so that the serial numbers can be reused.

What is IMEI number of your mobile handset ?

The IMEI (International Mobile Equipment Identity) number of a mobile handset is a 15 digit number unique to a mobile handset.   Just key in *#06# on your cellular phone and it will display its IMEI number in most phones. Note it down safely. It is also usually printed on the compliance plate of the handset.

In fact each GSM mobile phone is assigned a unique IMEI code when it is produced. If you know the IMEI code of a mobile phone, you can check information regarding manufacturer, model type, date and country of approval.

IMEI number can help in tracking or blocking your mobile phone if it is lost. When a phone is switched on, the IMEI number is transmitted and checked against a database in the network's EIR (Equipment Identity Register). The EIR has three categories namely the "white lists", "grey lists" and "black lists". The operator can block a handset by putting it in black list. Also by using Global Positioning System an operator can track the handset user also. But the use of these lists and technologies is at the operators' discretion. Generally operators provide these services in case of special investigations only.
