Which Barcode Format Should I Use?
EAN-13 and UPC-A are the standard formats for retail products sold in stores (EAN-13 outside North America, UPC-A within it) and require a registered product code to be scannable at checkout systems. Code 128 and Code 39 are flexible, unregistered formats ideal for internal tracking, assets, and shipping labels. Data Matrix and PDF417 are 2D formats that pack more data into a smaller space, often used for tickets and ID documents.

Frequently Asked Questions
Can I use these barcodes for real retail products?
For EAN-13/UPC-A codes to work at retail checkout systems, the code number itself must be officially registered with GS1. iCreatePDF generates the correct visual barcode for any number you enter, but registration is a separate step handled outside this tool.
Will the generated barcode scan correctly?
Yes — codes follow the standard encoding specification for each format, so any compliant barcode scanner or scanning app can read them.
Can I generate multiple barcodes at once?
Generate and download codes one at a time through the tool; for bulk batches, repeat the process for each value you need.
What size should I print barcodes at?
Keep to at least the minimum recommended width for your chosen format — very small prints can become unreadable to standard scanners.
