What is this

The serial number (English Serial Number or SN) is a unique identification number of the device, which can consist of both Arabic numerals and Latin letters. It's like an identification number in a person's passport. In this ridiculous-looking combination of letters and numbers, very important information is encrypted. It is almost impossible to decipher what the numbers and letters mean, since each manufacturer has its own code based on the marking adopted in a particular company. But herechecking the device for uniqueness with this code is as easy as shelling pears.

What is used for

For the most part, the serial number is needed by the manufacturer himself, so that you can understand which batch of products is "defective" and who developed it. This practice was introduced in order to be able to somehow organize service and punish those responsible for the marriage. If this code does not correspond to what is indicated in the manufacturer's documents, then the warranty service of the device will not be performed, since the product will turn out to be "gray". Many official websites of manufacturers of computer components or other gadgets are equipped with a product search system by serial number. So the end user can check the originality of a device.

Where to find

Where can I find the serial number of this or that device? It depends on which device you are talking about. If it's a smartphone, then the serial number in budget models is written on a piece of paper glued under a removable battery inside the case.

You can also see the desired combination of characters in the smartphone itself. You need to go to "Settings", and then to the item "About phone". The number will be listed there. If we are talking about devices such as car radios, then the claim combination will be written on the box itself, also correspondingThe sticker will be present on the head unit case.

Computer part number

This is a very interesting situation. Checking the serial number of computer components can be done both by a simple inspection of the device, and using the software capabilities of the operating system. You can also see the number of computer components using applications such as AIDA64 and Everest. Also, the desired combination of numbers and letters can be pasted on the component itself. This number may also be written on the boxes of accessories. By the way, a good opportunity to check the correct spelling of the number on the box is to run "Everest" or "Aida" and see if it matches what is hammered into the firmware of the component itself. If it does not match, then the product is "gray".

Printed circuit boards

These include things like RAM modules, some video cards, motherboards, sound cards, and others, where the serial number is usually found on the board itself. Moreover, it is written in such a way that it is not possible to correct any letter in it. The number is applied by laser engraving and covered with a layer of special varnish, which is used in the radio business. Needless to say, it is very difficult to fake such things. But some make it. Therefore, it does not hurt to check the code programmatically. Suddenly it does not match the engraved? But this is unlikely. Even if the product is "gray", the craftsmen will take carefor the numbers to match. Maybe not always.

Feature telephone number

Unfortunately, the serial number cannot be verified in this way. But it is quite possible to find it in the settings. In the "About phone" section.
