Often, when a call comes from an unknown number, or you need to call a subscriber within a certain tariff, it becomes necessary to find out the mobile operator by the number. The first few digits can help you with this.
Instructions
Step 1
Use the DEF-code to find out the operator by phone number. These are the first 3 digits of the phone number after the international code. For example, for the number + 7-908-888-55-11 it is the sequence 908. Each operator has one or several DEF-codes at once to serve subscribers. In this case, several operators can use one DEF-code at once.
Step 2
The easiest way to find out the operator is by the phone number of one of the largest mobile operators. DEF codes 910-919 and 980-989 are relevant for MTS. You can identify a Beeline subscriber by dialing numbers 903-906, 909 and 960-968. Megafon uses codes 920-929, 930-938 and 997. Various regional operators use DEF codes such as 900, 908, 940, 950-956. A value of 954 corresponds to satellite operators.
Step 3
If you are unable to find out the operator by phone on your own, try using special online services. On the Internet, you can find a fairly large number of sites that provide this opportunity. They have the same principle of operation and differ only in the interface design. The most effective will be those resources that display the subscriber's region on the map. Among them - https://ismska.ru/whois/; https://teleum.ru/help/codes/operator; https://sbinfo.ru/operator.php etc.
Step 4
Try using specialized programs to find out the operator by the cell number. They have a built-in DEF code base that allows you to uniquely identify the operator. For Java mobile phones download the PhoneWizard app. Operators of Russia are suitable for smartphones and PCs. The Mobile Operators application works in the same way.
Step 5
Punch the DEF code through any of the internet search engines. So you can immediately go to the detected number in one of the online databases or on the website of the corresponding operator. If you are registered with social networks, you can try to search for the number through their search engine. In some cases, you will be able not only to find out the telecom operator, but also to identify the subscriber who uses this phone number.
