FAQ
Q: What is the difference between Code 128 and Code 39?
A: Code 128 encodes the full ASCII character set (letters, digits, symbols) and is more compact, making it the most widely used barcode in logistics and shipping. Code 39 is older and only encodes uppercase letters, digits 0–9, and a few symbols, but is still common in industrial and government applications.
Q: When should I use EAN-13 or UPC-A?
A: EAN-13 (13 digits) and UPC-A (12 digits) are standardized retail product barcodes used on consumer goods worldwide. These require a registered GS1 company prefix for commercial use.
Q: Can I use the generated barcodes commercially?
A: The barcode image itself is free to use. However, for retail barcodes (EAN-13, UPC-A), the encoded number must be a registered GS1 number if used on products sold in stores.
