Barcode and SKU System Setup Guide for Indian Retail

A shop owner decides to start scanning. Someone tells him he needs to register for barcodes. He pays for a subscription, waits for a company prefix, and never once needed any of it.

Because a GS1 barcode is a commercial requirement, not a legal one. No Indian law says a shop must create a GS1 barcode for its own products. What forces your hand is who you sell to. Sell through Amazon, Flipkart, or a retail chain, and their system needs a number it recognises. Scan at your own till, and it does not.

GS1 keeps prefix 04 outside the global pool for exactly this. Its specification says any company in the world may use that range for internal numbering, under its own control, with no licence and no registration. Numbers on it can never clash with a branded product, and any point of sale software that lets you give a product its own barcode can print them. For a kirana or grocery store, that is the whole answer.

The second problem costs more and shows up later. Nobody designs the SKU system. Staff invent codes as they go, and within a year the same shirt exists as SHIRT-RAY-BLU-M, as shirt_raymond_blue_m, and as 10023. Now your stock report counts one product three times, and no report you run is trustworthy.

Renaming two hundred SKUs is an afternoon. Renaming two thousand, across printed labels and years of old bills, is a project you will keep postponing forever. This is the decision you want to get right in month one, not month thirty.

This guide settles both. It tells you whether you need GS1 at all, gives you SKU patterns by trade that still work at ten times your range, covers the scanner and printer choices honestly, and lists what your labels must legally declare under the Legal Metrology rules.
