Where Barcodes Are Used
A barcode generator is a practical necessity for any business that tracks physical products, assets, or documents. Retailers print barcodes on product labels and price tags so checkout scanners instantly retrieve item and pricing data. Warehouses rely on a barcode generator to create tracking labels for storage bins, pallets, and individual stock items. Libraries assign barcodes to book spines to automate lending and returns. Healthcare facilities use barcodes on medication vials and patient wristbands to prevent dispensing errors.
Frequently Asked Questions
What barcode formats are supported?
This barcode generator supports CODE128, EAN-13, EAN-8, UPC-A, CODE39, ITF-14, and MSI — the most widely used formats in retail, logistics, manufacturing, and inventory management.
What is the difference between CODE128 and EAN-13?
CODE128 is the most flexible option in any barcode generator — it encodes any alphanumeric characters and suits internal tracking, shipping labels, and inventory barcodes. EAN-13 is a fixed 13-digit numeric format used specifically for retail product identification on store shelves worldwide.
PNG or SVG — which should I use?
Use SVG if you need to print the barcode at any size without quality loss — SVG is vector-based and scales perfectly. Use PNG for digital applications, websites, or systems that don't support SVG.
Why does my EAN-13 barcode show an error?
EAN-13 requires exactly 13 numeric digits (no letters or symbols). The 13th digit is a check digit — when you enter a 12-digit number, this barcode generator automatically calculates and appends the correct check digit. If you enter all 13 digits, the last one must already be correct.
What is the difference between a barcode and a QR code?
+A traditional barcode is one-dimensional — it stores data in a single row of varying-width lines and holds around 20 to 25 characters. A QR code is two-dimensional, storing data in a grid of black and white squares and holding up to several thousand characters including URLs, contact details, and binary data. QR codes also have built-in error correction that allows them to be read even when partially damaged.
Which barcode format should I use for my product?
+For retail products sold internationally, use EAN-13 (or UPC-A in North America). For internal logistics and warehouse labels, choose CODE128 in your barcode generator — it supports the widest range of characters and is accepted by most scanners worldwide. For books, use ISBN-13, which is an EAN-13. If you are unsure, CODE128 is the safest default.
