The Classic Striped Barcode
When most people picture "a barcode," this is what comes to mind: a single row of black stripes of varying widths, printed above a line of numbers, found on nearly every retail product. These are called 1D (linear) barcodes, and — unlike a QR code or Data Matrix — they store data in only one direction, which limits them to a short string of digits or characters. That's a feature, not a limitation, for the jobs these formats do best: a fast, universally recognized lookup number that any point-of-sale scanner has read the same way for decades. Looking for a 2D format instead? See QR Codes or 2D Barcodes.
Code 128
The Code 128 Barcode Generator creates one of the most versatile 1D formats around — compact, able to encode any letter, number, or symbol, and a common sight on shipping labels and inventory tags.
UPC & EAN
The UPC & EAN Barcode Generator creates the exact barcode format printed on retail packaging worldwide — UPC-A in the U.S. and Canada, EAN-13 almost everywhere else — complete with an automatically calculated check digit.
Code 39
The Code 39 Barcode Generator creates a simple, self-checking format long favored in inventory systems, the automotive industry, and defense and government logistics.
ITF-14
The ITF-14 Barcode Generator creates the standard barcode format for shipping cartons and pallets — the case-level code that sits above the individual UPC/EAN codes on the products inside.
Codabar
The Codabar Generator creates a format still widely used in libraries for library cards and books, and by blood banks for tracking donations.
