FAQ

Barcode basics,
without the jargon.

Which barcode type should I use?

Use Code 128 for a flexible internal identifier. Choose EAN-13 or UPC-A for retail products, EAN-8 for smaller retail packaging, Code 39 for established industrial workflows, and ITF-14 for shipping cartons and cases.

Does QRalto calculate check digits?

Yes. For EAN-13, UPC-A, EAN-8 and ITF-14 you can enter the data digits and QRalto calculates the final check digit. If you enter the full number, QRalto verifies that check digit before rendering.

Does QRalto issue UPC or EAN product numbers?

No. QRalto generates and validates barcode artwork; it does not issue GTINs, UPCs or EANs. For retail use, use a product number assigned by GS1 or another source accepted by your trading partners.

Can I customize barcode colors?

Yes, within scan-safe limits. QRalto requires dark bars on a light background with strong contrast because decorative choices should never come before scanner reliability.

Are QR codes and barcodes the same?

No. A barcode usually encodes a compact identifier directly, while QR codes can hold more information and QRalto dynamic QR codes can route to editable hosted destinations. QRalto keeps both tools in one workspace without mixing their technical behavior.
