I once watched a small candle maker lose a wholesale deal because her products had no scannable barcodes. The buyer loved the candles; the warehouse system could not receive them. She got compliant barcodes that same afternoon and the deal closed the next week. Barcodes are boring right up until they are worth money.
This generator covers the three formats you will actually encounter: EAN-13 for retail products sold internationally, UPC-A for North American retail, and Code 128 for logistics, labeling, and internal tracking (it encodes full ASCII, so serial numbers and lot codes work too).
How to use it: pick the format your buyer or system requires, type the digits, and download the image. Two rules from experience: first, confirm the format before printing a thousand labels, retailers reject the wrong symbology outright. Second, test-scan with a phone before any print run; a barcode that looks fine but does not scan is just decoration.

My hard-won tip: for retail products you sell yourself, get proper registered numbers (GS1) rather than inventing digits, duplicate numbers cause chargebacks and delistings. For internal warehouse labels, Code 128 with your own scheme is perfect and free forever.
Bottom line: right format, real numbers, test scan. Then print with confidence.
