For example, if a mobile phone is stolen, the owner can have their network provider use the IMEI number to blacklist the phone. The IMEI only identifies the device and has no particular relationship to the subscriber. SIM card that can, in theory, be transferred to any handset. Many countries have acknowledged the use of the IMEI in reducing the effect of mobile phone thefts. Act, changing the IMEI of a phone, or possessing equipment that can change it, is considered an offence under some circumstances.
IMEI blocking is not the only way to fight phone theft. For example, Singapore’s regulator does not require mobile operators to implement phone blocking or tracing systems, IMEI-based or other. The regulator has expressed doubts about the effectiveness of this kind of system in the context of the mobile market in Singapore. The existence of a formally allocated IMEI number range for a GSM terminal does not mean that the terminal is approved or complies with regulatory requirements.

In New Zealand the NZ Telecommunications Forum Inc provide a blocked IMEI lookup service for New Zealand consumers. The service allows up to three lookups per day and checks against a database that is updated daily by the three major mobile network operators. A blocked IMEI cannot be connected to any of these three operators. In some countries, such blacklisting is not customary.
