Global Trade Item Number

The Global Trade Item Number ( GTIN ) is a managed and allocated by the GS1 identification number can be used to uniquely identify products and packages worldwide. GTIN is an umbrella term for code schemes of barcode labels with EAN, Code of the UCC or the EPC. For the award of the GS1 organization in each country is responsible. These schemes include the bar code label:

The GTIN-14 is by prefixing the leading zeros from the previous 13 - and formed 8-digit part numbers - 12:

Logistic units GTIN 14

The first digit of the 14-digit GTIN has the following meaning:

Logistic units GTIN 13

The first three digits are the country code used (GS1 country prefix, eg is 760-769 Switzerland and Liechtenstein ). But they are not the same as the country of manufacture. After that is the 4 -, 5 - or 6- digit operation number of the manufacturer. After the middle character is followed by the 5 -, 4 - or 3 - digit item number ( depending on the length of operation number) of the manufacturer. The last digit is a check digit, which is used for electronic data processing as a safety to prevent errors.

Since the GTIN code has a total of 13 digits, it is called a GTIN 13 (formerly EAN -13). The first part of the country code (in this case 4) is not represented by bars, but encrypted indirectly through the check digit. Besides GTIN is in the retail trade and the GTIN 8 (formerly EAN -8) in use. This has eight digits, four between the two edge -and medium characters.

Calculate the check digit:

The digits of the GTIN - 13 codes are alternately multiplied by the digit combination 1-3. The individual results are summed and the difference to the nearest multiple of ten equals the check digit.

Example:

GTIN 13: 4 0 3 4 5 6 7 8 9 0 1 2?                              * Digit combination: 1 3 1 3 1 3 1 3 1 3 1 3 - Yield: 4 0 3 5 12 18 7 24 9 0 1 6 = 89 The sum of the added numbers gives 89 It is rounded up to the nearest ten, ie 90 Since the difference of 89 and 90 results in 1, this is equal to the check digit.

So the GTIN is 13 Code: 403 456 789 012 1
