Your GS1 company prefix is the root number every one of your GTINs is built from. It's issued once per business (not per product) and stays with you as long as your registration is active.
What the prefix actually encodes
A company prefix is a block of digits reserved exclusively for your business, at the start of the GS1 identifier system's numbering hierarchy. GS1 India allocates it; you then generate individual product-reference numbers within that block to create each GTIN.
Why prefix length varies
Businesses that expect to need very large numbers of distinct GTINs are typically issued a shorter prefix (leaving more digits free for product references), while businesses with modest catalogs receive a longer prefix with a smaller product-numbering range. This is why two businesses of different sizes don't necessarily get comparably-sized number blocks.
Why you can't borrow someone else's prefix
Because a prefix is tied to a specific legal business entity, a private-label manufacturer can't simply issue GTINs under a client's prefix, and a brand can't resell products under a supplier's prefix. Ownership of the prefix is what makes the GTIN traceable back to a specific, accountable business — reusing someone else's breaks that chain.
Keeping your prefix active
A prefix requires ongoing annual renewal. If it lapses, the numbers you've already printed on existing packaging don't automatically become invalid overnight, but you lose the right to generate new GTINs under it until it's reinstated — worth building renewal dates into a compliance calendar rather than tracking them manually.
