Why do I have to have a new Global Company Prefix (or GCP) when I get a new batch of numbers?

A GTIN usually consists of 13 digits. The first 7 to 9 digits are your Global Company Prefix (GCP) – which you license from GS1. The length of the prefix determines how many numbers you receive – the shorter the GCP, the more numbers you get. The last digit of the GTIN is always a check digit, calculated automatically to ensure integrity. So, the remaining digits in the middle are used to uniquely identify your products – and these form your GTIN range. Once you exhaust the numbers within your current range, it’s impossible to add more numbers beginning with the same prefix. Therefore, a new prefix is issued.
