If you sell products to a distributor or a retailer, you will need a UPC barcode. Although it is best to contact the company selling your product to find out their policy on UPC barcodes. When you obtain your UPC number, you will also get a certificate authenticating your number. Most retailers require proof of the certificate to verify that your number is unique and authorized. Here are some examples:
- Tracking internal inventory-No
- Selling products directly to customers-No
- Selling products through a distributor or retailer-Most of the time
- Selling products through a major national store-Yes
