Frequently Asked Questions

Which barcode type should I use for retail products?

For US and Canadian retail products, use UPC-A (12 digits). For international retail outside North America, use EAN-13 (13 digits). Both formats require a Modulo-10 check digit, which our generator automatically calculates.

What is the best barcode format for inventory & warehouse tracking?

Code 128 is the industry standard for internal inventory, shipping labels, and asset tags. It supports letters, numbers, and special characters with high data density.

Do generated barcodes expire?

No. All barcodes generated by this tool are standard static barcodes. They encode raw text or numbers directly into physical bars and will work indefinitely.

Is my product or SKU data safe?

Yes, 100% private. All rendering happens in your web browser memory using client-side JavaScript. No data is sent to external servers.
