UPC and barcodes

No scan, no sale. Get this right before you send a sample.

  1. 1Ensure your product scans at receiving and at register.
  2. 2Use one unique barcode per sellable unit, size and flavor.
  3. 3Test printed labels on the real pack cold and wet before shipping.

A premium store runs on its item file. If your product cannot be scanned at receiving and at the register, someone has to key it by hand, and that someone will remember you for it.

What a store needs

One barcode per sellable unit, and it has to be yours. Every size and every flavor is its own item with its own code. A code borrowed from another company's prefix, or one code shared across two flavors, will fail the first time a store tries to set you up.

If you sell by the case, the store may also ask for a case code so the dock can receive without opening the box.

Where brands go wrong

  • One code for a whole range, with flavors told apart by the label.
  • A barcode printed too small, on a curve, or over a seam, so it will not scan.
  • Changing the size or the formula and keeping the old code.

To get UPC barcodes for your products, license your product numbers (GTINs) through GS1 US for a one-time fee of $30 each, or get a GS1 Company Prefix for 10 products starting at $250 upfront and $50 per year. Within minutes of payment, GS1 US emails you access to its online portal, where you can assign your numbers and download barcode artwork for your packaging. Get started with GS1 US

Check it yourself

Print the label, wrap it on the real pack, and scan it with a phone and with a handheld scanner if you can borrow one. Then scan it again cold and wet, the way it will sit in a cooler.

Do this

List every item you sell, one row each, with its barcode, size and case pack. That one page is the start of the item data every buyer will ask you for.
