What makes a SKU worth having
A SKU is only useful if you can read it back. Sellers who generate random strings end up opening a spreadsheet every time someone asks “which one is the red kurti in L” — which is exactly the work the SKU was supposed to remove. A good code answers that question on its own, on a courier slip, in a WhatsApp message, on a carton label.
The pattern this tool uses is shop-category-colour-size-number. So MEERA-KRT-RED-L-004 is readable at a glance by you, by your packer, and by anyone helping you dispatch on a busy day. The number at the end keeps it unique even when the same product comes back in a new lot.
Keep the code short enough to write by hand. Anything past about twenty characters stops being written on a polybag and starts being skipped, and a SKU that gets skipped is worse than no SKU.
How to use these codes once you have them
Put the SKU in three places and it starts paying for itself. First, in the marketplace listing — both Meesho and Flipkart accept a seller SKU field, and that is what ties a settlement line back to a product. Second, on the physical stock, on a slip inside the polybag. Third, in your own stock register.
Rename your photo files to match. A folder where the image is called MEERA-KRT-RED-L-004.jpg rather than IMG_20260818.jpg removes the single most common listing error, which is uploading the wrong colour against the right title.
Download the CSV and keep it as your master list. When you add a new lot, start the numbering where the last one ended rather than at 001, so no two products ever share a code.

Frequently Asked Questions
What is a SKU code?
SKU stands for Stock Keeping Unit. It is a short code you assign to one exact product variant — a specific style in a specific colour in a specific size — so that you, your marketplace listing and your stock register are all talking about the same thing.
How do I create SKU codes for my products?
Use a readable pattern rather than random characters. Category, colour, size and a running number covers almost every clothing business: KRT-RED-L-004 tells you it is a red kurti in large. This tool builds every combination for you and exports a CSV.
Does Meesho need a SKU?
Meesho asks for a seller SKU when you list, and it is what connects a settlement line back to a product. You can type anything, but a consistent readable code is what makes your payment reports legible three months later.
How many characters should a SKU be?
Short enough to write by hand on a polybag — roughly twenty characters or fewer. Longer codes get skipped during a busy dispatch, and a skipped SKU is worse than none at all.
Is this SKU generator free?
Yes. No signup, no limit, and nothing is uploaded — the codes are generated inside your browser, so it works on a weak connection.
