Sometimes situations arise when someone called, but you could not pick up the phone, and the number displayed on the screen is unfamiliar. You are beginning to wonder who it could be. But it's embarrassing to make a callback, or you are simply afraid to stumble upon scammers, as a result of whose actions a rather large sum of money may disappear from your personal account.
Instructions
Step 1
Learn the standard dialing rules. Once you get the general information, it will be much easier to navigate to figure out where the call came from. When entering a long distance and international number from a regular landline phone, you must enter certain combinations of numbers. To make a long-distance call - 8 - dial tone - at the end of the area code and subscriber number; for international connection - 8 - dial tone - then 10 - country code - then area code and telephone number.
Step 2
After analyzing the information received, you can easily determine the territorial affiliation of the caller. To make a long distance call to a mobile number, dial - +7 - area code - and then the phone number; when making an international call, use the combination - + country code - then city code - subscriber's phone.
Step 3
Now that you are familiar with the basic combination of numbers, move on to defining the country code. Use the telephone directory or internet services to find the list of state dialing codes and locate the country or city from where you were called.
Step 4
Sometimes it may be that the caller hid their mobile phone number. This is usually done for the purpose of extortion, pranking, or simply to intrigue a person. An automatic service for subscribers can help to identify the "joker". Call your operator's call center and wait for the answering machine to speak. He will tell you what needs to be done next. Using the prompts, go to the service for adding / deleting services and enable the option with which any calls, even hidden ones, are determined.
Step 5
Another way to identify the caller is to request a detailed printout of the incoming call. If you are intermittently harassed on the phone and there is no way to identify the caller, the operator may provide a service that is commonly referred to as Malicious Call Identification. You just need to dial the combination of numbers indicated in the detailed instructions.
