How many digits should a GTIN contain?

In trade item information a GTIN must always consist of 14 digits. If you use 13- or 8-digit numbers, these should be padded to the left with zeroes. It is only the format of the item number which is changed; the meaning of the number is not affected.

Example:

  • GTIN-13: 07300011000017
  • GTIN-8: 00000073000013
