Generating barcodes for products you sell?
A barcode is only useful if you can track what it's attached to. VNDLY auto-assigns barcodes to every product, then tracks stock, sales, purchasing and reorders across all your channels — scan with your phone, no extra hardware.
UPC barcodes for retail inventory
The UPC-A barcode is the 12-digit code scanned at checkouts across the US and Canada. If you sell physical products through retailers or major marketplaces, a valid UPC is usually a requirement, because it gives every product a standardised identifier their systems already understand.
For real retail listings you will want genuine UPC numbers built on a GS1-issued company prefix, so each one is globally unique. This generator renders any valid number into a clean, scannable barcode you can print on labels and packaging. It does not register numbers with GS1.
Once products carry UPCs, the next step is tracking stock against them. That is where VNDLY comes in: link each product to its barcode, then scan with your phone to receive purchase orders, run counts, and fulfil sales, all in one system.
Frequently asked questions
- What is a UPC barcode?
- A UPC (Universal Product Code) is the 12-digit barcode scanned at retail checkouts in the US and Canada, printed in the UPC-A symbology. The number it encodes is a GTIN, the standardised product identifier retailers recognise.
- Is this UPC generator free?
- Yes. It is completely free, no signup and no watermark. Everything is generated in your browser, so the numbers you enter never leave your device.
- Can I sell products with a UPC I generate here?
- This tool turns any valid 11 to 12 digit number into a scannable UPC-A barcode. To sell retail products through major retailers or marketplaces, you usually need a genuine UPC based on a GS1-issued company prefix, so the number is globally unique. This tool renders the barcode; it does not register the number with GS1.
- What is the difference between UPC and EAN?
- UPC-A is the 12-digit standard used in the US and Canada. EAN-13 is the 13-digit equivalent used in most of the rest of the world. Both encode a GTIN and both are read by the same retail scanners.
- How do I track stock against these UPCs?
- Generating the barcode is step one. To track sales, stock levels and reordering against it, you need inventory software. VNDLY links each product to its barcode and lets you scan it with your phone to receive, count and fulfil, no extra scanner hardware required.
