BarcodeDesk is a barcode image generator, not a barcode-number issuer
BarcodeDesk turns a value you provide into a real, correctly-encoded barcode image or file. It does not issue, register, or verify official UPC, EAN, or GS1 identification numbers. If you have a number like 012345678905, BarcodeDesk will generate the correct corresponding barcode — but that doesn't make it an officially registered product identifier. Official GS1 numbers are obtained from GS1 or your product's original issuer, not generated here.
Check digits are calculated, not verified against a registry
For formats like EAN-13, UPC-A, and ITF-14, BarcodeDesk calculates the mathematically correct check digit for whatever payload you enter. That confirms the barcode is internally consistent and will decode back to the value you intended — it does not confirm that the underlying number is a real, registered product in any database. A mathematically valid EAN-13 and an officially registered one are two different things, and BarcodeDesk can only guarantee the former.
Scan reliability depends on how you print it
Every format BarcodeDesk supports is verified with an independent, round-trip decode test at generation time — the barcode is real and correctly encoded. But whether a printed copy scans reliably also depends on factors BarcodeDesk doesn't control: print resolution, paper and ink quality, label size, and the scanner or app reading it. BarcodeDesk warns you in the generator when a chosen display size would compress a barcode below a safe, scannable density — take that warning seriously, and test a printed sample with a real scanner before using barcodes for production or compliance purposes.
Trademarks and standards
Barcode symbology names referenced on this site — Code 128, Code 39, EAN-13, UPC-A, ITF-14, Data Matrix, PDF417, GS1-128, and others — refer to open technical standards maintained by organizations including GS1 and ISO/IEC. BarcodeDesk is not affiliated with, endorsed by, or officially connected to GS1, ISO, or any standards body. These are technical specifications for barcode structure, not brands BarcodeDesk is claiming association with.
Not compliance or legal advice
Some industries — pharmaceuticals, food, medical devices, and others — have specific regulatory requirements for product barcoding beyond correct encoding (serialization rules, specific GS1 Application Identifiers, labeling regulations, and similar). BarcodeDesk is a general-purpose encoding tool, not a compliance product, and using it doesn't by itself satisfy any industry-specific regulatory requirement. If your use case is regulated, consult the relevant standard or a qualified professional before relying on BarcodeDesk's output for that purpose.
No liability for business use
BarcodeDesk isn't liable for losses arising from a barcode that fails to scan after printing, from using BarcodeDesk in place of an officially issued product identifier where one was required, or from relying on BarcodeDesk's output to satisfy a regulatory requirement it wasn't designed to meet. See the Terms of Service for the full liability terms.
