Selling wholesale means your products need to scan cleanly in your buyers’ systems. Here’s the barcode side.
Unit and case codes
Your individual retail units need a UPC/EAN. If you ship by the case, buyers may also want an ITF-14 case code.
Get both levels right to be retail-ready.
Know your buyers’ rules
Some large retailers require GS1-registered numbers; many independents accept valid GTINs. Confirm each buyer’s vendor requirements before committing.
This avoids re-barcoding after the fact.
Be retail-ready
Clean, unique, scannable barcodes make you easy to onboard as a supplier. Keep a master list mapping products to numbers.
Consistency speeds up purchase orders and reduces disputes.
