Frequently Asked Questions
Everything you need to know
What is the difference between a Barcode and a QR Code?
Barcodes represent data in one dimension (linear bars) and typically encode short alphanumeric identifiers (like product IDs). QR codes represent data in two dimensions (matrix grid) and can encode much larger datasets like web URLs, email templates, contact cards, and payment protocols.
Which barcode format should I choose?
Choose CODE128 for general inventory, shipping tracking, or internal warehouse labels. Choose EAN-13 for packaging commercial retail goods globally (outside North America). Choose UPC-A if your product will be sold in US or Canadian retail outlets.
Do I need standard registration to use these barcodes?
If you are using barcodes internally for warehouse tracking, employee badges, or library catalogs, you do not need any registration. However, if you are selling products in commercial retail stores, you must obtain licensed barcode numbers from GS1.
Can I print these barcodes using a normal office printer?
Yes. You can print these barcodes using standard laser or inkjet printers. Make sure to print on high-contrast white paper, avoid resizing that makes the lines blurry, and check that the ink doesn't smudge so scanners can read them easily.
What characters are supported in CODE128 vs EAN-13?
CODE128 supports all ASCII characters (letters, numbers, and symbols). EAN-13 supports only numeric digits (0-9) and must be exactly 12 digits (our generator adds the 13th checksum digit automatically) or 13 digits long.
