What Is a Barcode?

A barcode is a machine-readable representation of data encoded in a pattern of parallel bars and spaces of varying widths. When scanned with a barcode reader or smartphone camera, the pattern is instantly decoded to reveal a product code, serial number, URL, or other data.

Barcodes were first used commercially in the 1970s on grocery packaging and are now everywhere: retail products, shipping labels, library books, event tickets, and warehouse inventory. They let businesses track items quickly and accurately.

FAQ

Frequently Asked Questions

What is the best barcode format to use?

CODE128 is the most versatile and widely used barcode format. It supports the full ASCII character set, is compact, and is readable by virtually all barcode scanners. For retail product codes, use EAN-13 or UPC-A. Choose EAN-8 or CODE39 for smaller items.

How do I create a barcode for free?

Type your text or number into Ercc's Barcode Generator, pick a format such as CODE128 or EAN-13, and click Generate. Your barcode is created instantly in your browser. Customize the size and colors, then download it as a PNG or SVG. No signup or payment required.

How many characters can a barcode hold?

Depending on the format, CODE128 can encode up to about 48 characters in a very compact form and supports the full ASCII set. Numeric formats like EAN-13 and UPC-A encode exactly 12 to 13 digits, while ITF-14 encodes 14 digits. CODE39 supports 43 characters.

Can I customize the colors of my barcode?

Yes! Ercc lets you choose custom bar (line) and background colors, plus the width, height and text size. Make sure there is enough contrast between the bars and background so the barcode remains scannable.

What is the difference between UPC and EAN barcodes?

UPC-A is a 12-digit code used mainly in the United States and Canada, while EAN-13 is a 13-digit code used internationally. EAN-13 is essentially a superset of UPC-A: a UPC-A barcode becomes a valid EAN-13 by adding a leading zero. Both encode retail product identifiers.

Is this barcode generator really free?

Yes, 100% free with no limits. There is no watermark, no signup, no ads, and no restrictions on how many barcodes you can generate. Everything runs locally in your browser —your data is never sent to any server.
