Frequently Asked Questions
What is the difference between UPC and EAN?
UPC-A is the 12-digit retail barcode standard used mainly in North America. EAN-13 adds a 13th digit that encodes a country prefix, making it the global standard. Most modern scanners read both interchangeably.
How does Code 128 differ from UPC?
UPC encodes numbers only. Code 128 encodes full alphanumeric text — letters, numbers, and symbols — which makes it the right choice for internal SKUs, shipping labels, and warehouse tracking where codes contain letters.
Will these barcodes actually scan?
Yes — the generated barcodes follow the GS1 bar-width specifications that commercial laser and camera scanners expect. For print use, keep adequate white space (the "quiet zone") on both sides and avoid scaling the image non-proportionally.
Is my product data sent anywhere?
No. Barcodes are drawn entirely in your browser — the SKUs or codes you enter never leave your device, which matters when generating codes for unreleased products.
Can I just make up a UPC number for my product?
For internal use, yes. But to sell through retailers or marketplaces like Amazon, UPC/EAN numbers must be licensed from GS1 — retailers validate the prefix against the GS1 registry, and made-up codes will be rejected.
