Frequently Asked Questions
Which barcode format should I use?
Use EAN-13 or UPC-A for retail products. Code 128 is the most versatile and supports all ASCII characters. Code 39 is common in logistics. Choose the format that matches your industry or scanning equipment.
What is the difference between a barcode and a QR code?
Barcodes are one-dimensional and encode data in parallel lines of varying width. QR codes are two-dimensional and can store more data. Barcodes are faster to scan and better for simple identifiers; QR codes are better for URLs and complex data.
Can I generate barcodes for retail products?
You can generate barcodes in retail formats like EAN-13 and UPC-A, but using them on products for sale requires a valid GS1 company prefix. This tool is ideal for internal use, testing, and prototyping.
