EAN-13 Generator

What Is an EAN-13 Barcode?

EAN-13 (European Article Number, 13 digits) is the international standard barcode for retail products, used in stores worldwide outside of North America — and increasingly alongside UPC-A within North America too, since UPC-A is technically a subset of EAN-13. Every EAN-13 barcode encodes a 13-digit Global Trade Item Number (GTIN-13): 12 data digits plus a final check digit. It's the barcode printed on nearly every packaged product you'd find on a supermarket or retail shelf outside the US and Canada.

Important distinction: Barcode Mint generates a correctly formatted, scannable EAN-13 barcode image from any 12 digits you provide. It does not register or assign an official GTIN. A GTIN that's actually unique in global retail systems has to be licensed from GS1 (the organization that administers the EAN/UPC numbering system) through a GS1 company prefix. If you're building a real retail product for sale through major retailers or marketplaces, you need a GS1-issued prefix — this tool is for generating the barcode image once you have (or are testing with) a number.

How EAN-13 Encodes Data — Structure and Check Digit

An EAN-13 barcode's 13 digits break down into three parts:

• Country/GS1 prefix (2–3 digits) — indicates which GS1 member organization issued the number, not necessarily where the product was made. For example, prefixes starting with 0 correspond to the US/Canada (UPC compatibility range), while other ranges map to GS1 organizations in specific countries.
• Company and item reference (9–10 digits) — assigned by the GS1 member organization to a specific manufacturer, then subdivided by that manufacturer to identify individual products.
• Check digit (1 digit) — calculated using a weighted modulo-10 algorithm across the preceding 12 digits, letting scanners detect a misread or mistyped digit.

You only need to type the first 12 digits into Barcode Mint; the check digit is calculated and appended automatically, so the barcode you export is always mathematically valid.

Where EAN-13 Is Used

EAN-13 is the default retail barcode across most of the world:

• Grocery and retail packaging — nearly every packaged consumer product sold in Europe, Asia, Australia, and most other regions carries an EAN-13 for point-of-sale scanning.
• E-commerce marketplaces — Amazon, eBay, and similar platforms often require a GTIN (EAN-13 or UPC-A) to list a new product.
• Inventory and warehouse management — retailers and distributors use EAN-13 to track SKUs through receiving, stocking, and sales.
• Books and media (as ISBN-based EAN-13) — modern ISBNs are formatted as EAN-13 barcodes with a 978 or 979 prefix.
• Cross-border retail — because EAN-13 is a superset of UPC-A, products can carry one code that scans correctly on both European and North American point-of-sale systems.

How to Create an EAN-13 Barcode in Barcode Mint

Select EAN-13 from the symbology list under Retail (EAN/UPC). Type your 12-digit number — if you have a real GS1-issued GTIN, use that; for testing or internal use, any 12 digits will produce a valid barcode. The check digit is calculated and displayed automatically as you type, and the live preview shows exactly what will print. From there:

• Adjust bar width and height — retail scanners are tuned to a fairly standard size range, so avoid shrinking the barcode too far below 80% of nominal size.
• Keep human-readable text (the digits below the bars) turned on for retail use — it's required by most point-of-sale systems and lets staff key in the number manually if a scan fails.
• Set the quiet zone (margin) correctly; EAN-13 needs clear space on both sides for scanners to detect the start and stop guard patterns.
• Export as PNG, SVG, or PDF for packaging artwork, or use Copy for quick placement in a design tool.
• Use batch/sequence to generate a numbered run of GTINs, or the bulk CSV → ZIP/PDF tool to turn a spreadsheet of product numbers into a folder or print sheet of barcodes.
• Call the REST API — /barcode?type=ean13&data=YOUR12DIGITS — to generate EAN-13 images programmatically from a PIM, ERP, or labeling pipeline.

Print and Scan Best Practices for Retail

Retail scanning environments are unforgiving, so a few rules matter:

• Size: GS1 specifies a nominal EAN-13 size, with an acceptable magnification range roughly from 80% to 200% of nominal — going smaller risks bars merging or failing to resolve under a laser or imager scanner.
• Quiet zones: leave clear space (no text, logos, or other marks) on both sides of the barcode — this is one of the most common reasons a technically correct barcode fails to scan at checkout.
• Contrast: print black bars on a white or light background; avoid low-contrast color combinations, and never print a barcode over a busy background pattern.
• Placement: keep the barcode flat, not wrapped around a curved edge or seam, and avoid placing it where packaging folds or creases could distort the bars.
• Verification: for any GTIN going into real retail distribution, verify the code with a barcode verifier or your retailer's onboarding requirements before mass printing — a barcode that looks fine on screen can still fail grading specs.

Common uses

• Retail product packaging sold in Europe, Asia, and most non-North American markets
• E-commerce marketplace listings requiring a GTIN
• Book and media packaging using ISBN-formatted EAN-13 codes
• Warehouse and inventory tracking of SKUs by GTIN
• Cross-border products needing one code compatible with both EAN and UPC scanners
• Internal or private-label products using a manufacturer's own numbering range
