How to decipher the barcode on the product packaging?
The barcode on the product packaging is a means of informing about the manufacturer of the product. Knowing how to read and correctly interpret the barcode, you can always be aware of where and by whom the product was produced, whether this product was produced legally or illegally.
A barcode is nothing more than a digital record in a certain sequence of the source of origin of a product.
There are several international EAN code structures (EAN 8, EAN 13). EAN 8 is usually used on large items.
How to decipher the barcode on the product packaging:
EAN 8 example:
XXX XXX XX X
- The first three digits XXX indicate the country code of the product's country of origin,
- The second three digits XXX mean the code of the company - the manufacturer of the product,
- The third two digits XX mean the item number,
- The last ninth digit X is the control one.
EAN 13 example:
XXX XXXX XXXXX X 5 012345 678900
- The first group of three digits XXX is the code of the country of origin of the product,
- The second group of four digits XXXX is the code of the company - the manufacturer of the product,
- The third group of five digits XXXXX is the article of the product,
- The last thirteenth digit of X is the control one.
The check digit specifies whether the product is legally or illegally produced.
How to calculate the check digit on a barcode:
Add all even numbers and multiply by three. Next, add up all the odd digits (except for the check digit) and add them to the previous sum multiplied by three. In the resulting number, leave the last digit, which is subtracted from 10. The difference must correspond to the check digit. This means that the product is legally produced.
Calculation of the check digit of the code in the photo:
0 + 2 + 4 + 6 + 8 + 0 = 20
20 * 3 = 60
5 + 1 + 3 + 5 + 7 + 9 = 30
60 + 30 = 90 (remove 9 and get 0)
10-0 = 10 (remove 1 and get 0)
