What is a 13 Digit Barcode (EAN-13)? Complete Guide with Examples

Q: What is a 13 digit barcode called?

A 13-digit barcode is called an EAN-13 barcode (European Article Number). It is the global standard for retail product identification, managed by GS1 and used in supermarkets, warehouses, and eCommerce platforms worldwide. The 13 digits encode a GS1 country prefix, a manufacturer code, a product code, and a single check digit for error detection.

Q: What is the last digit in an EAN-13 barcode?

The last (13th) digit is the check digit. It is mathematically derived from the first 12 digits using the GS1 Mod-10 algorithm and serves as an error-detection mechanism — scanners use it to verify that the barcode was read or entered correctly. Any valid generator adds it automatically.

Q: What is the difference between EAN-13 and EAN-8?

EAN-8 is a shorter 8-digit variant designed for small products where a full 13-digit barcode would not physically fit. It uses the same check digit algorithm but encodes less information. EAN-13 is the standard for the vast majority of retail products and is required by most retailers and online marketplaces.

If you've ever scanned a product at a store, you've likely used a 13 digit barcode, also known as an EAN-13 barcode. It is one of the most widely used barcode formats in the world, especially in retail and eCommerce.

In this guide, you'll learn what an EAN-13 barcode is, how it works, and how to generate one easily.

What is a 13 Digit Barcode?

A 13 digit barcode is a numeric code used to identify products globally. It consists of 13 digits and is commonly referred to as an EAN-13 barcode.

EAN stands for European Article Number, but today it is used worldwide as part of the GS1 standard.

Example:
5901234123457

This number is encoded into a scannable barcode that stores product information.

Key Features:

Always 13 digits
Used globally
Machine-readable (via barcode scanners)
Supports error detection using a check digit

Structure of EAN-13 Barcode (Explained)

An EAN-13 barcode is divided into 4 parts:

Country Code (GS1 Prefix)
The first 2–3 digits identify the GS1 member organization that issued the barcode. Common examples: 400–440 = Germany, 500–509 = United Kingdom, 890 = India, 000–019 = United States (UPC-compatible). Note: the prefix identifies the issuing GS1 organization, not necessarily the country where the product was made.
Manufacturer Code
Identifies the company that produces the product.
Product Code
Unique identifier for the product.
Check Digit (Last Digit)
Used to verify if the barcode is valid. Check our EAN-13 Check Digit calculator to verify your barcodes.

Example Breakdown:
590 | 1234 | 12345 | 7

How EAN-13 Check Digit Works

The last digit of every EAN-13 barcode is a check digit - calculated automatically from the first 12 digits using the GS1 Mod-10 algorithm. It lets scanners instantly detect if a barcode was entered or printed incorrectly.

Common Mistakes When Using EAN-13 Barcodes

Wrong digit count — EAN-13 always requires exactly 13 digits. Entering 12 without letting the tool calculate the check digit will produce an invalid barcode.
Manual checksum errors — If you calculate the check digit yourself, a single arithmetic mistake makes the whole barcode invalid. Use the check digit calculator to verify.
Invalid GS1 prefix — Using a prefix not registered to your organization can create conflicts with other products in retail systems.
Print size too small — EAN-13 barcodes have a minimum recommended size. Printing too small causes scanner read failures at point-of-sale.

Frequently Asked Questions

What is a 13 digit barcode called?

A 13-digit barcode is called an EAN-13 barcode (European Article Number). It is the global standard for retail product identification, managed by GS1 and used in supermarkets, warehouses, and eCommerce platforms worldwide. The 13 digits encode a GS1 country prefix, a manufacturer code, a product code, and a single check digit for error detection.

Can I generate an EAN-13 barcode for free?

Yes — our free EAN-13 barcode generator creates valid barcodes instantly with no signup, no watermarks, and no usage limits. Enter 12 digits, and the tool automatically calculates the correct check digit and produces a downloadable PNG or SVG image. Bulk and sequential generation are also supported for product ranges and inventory labeling.

Is EAN-13 valid worldwide?

Yes. EAN-13 is administered by GS1, a global standards organization, and is recognized by retail systems in over 150 countries. It is the required barcode format for most international marketplaces and supply chains. The only major exception is legacy point-of-sale systems in the United States and Canada that were built specifically for UPC-A — though most modern US scanners accept EAN-13 as well.

What is the last digit in an EAN-13 barcode?

The last (13th) digit is the check digit. It is mathematically derived from the first 12 digits using the GS1 Mod-10 algorithm and serves as an error-detection mechanism — scanners use it to verify that the barcode was read or entered correctly. You never need to calculate it manually; any valid generator adds it automatically. To understand how it is calculated, see our EAN-13 check digit guide.

Can UPC be converted to EAN-13?

Yes. A UPC-A barcode is simply an EAN-13 with a leading zero — prepend 0 to any 12-digit UPC-A code and you have a valid 13-digit EAN-13. For example, UPC 012345678905 becomes EAN-13 0012345678905. This means any scanner that reads EAN-13 can also read UPC-A barcodes. The reverse only works if the EAN-13 already starts with a zero. For a full comparison of both formats, see our EAN vs UPC guide.

Where are EAN-13 barcodes used?

EAN-13 barcodes are used across the entire retail and logistics chain: supermarket checkouts, warehouse inventory systems, eCommerce product listings (Amazon, eBay, and most global marketplaces require a valid EAN or UPC), shipping and receiving operations, and manufacturing production lines. Any product sold internationally is expected to carry a valid EAN-13 barcode registered through GS1.

What is the difference between EAN-13 and EAN-8?

EAN-8 is a shorter 8-digit variant of the EAN standard, designed for small products where a full 13-digit barcode would not physically fit — think lip balm tubes, pencils, or small cosmetic items. It uses the same check digit algorithm but encodes less information. EAN-13 is the standard for the vast majority of retail products and is required by most retailers and online marketplaces.

Do I need to register with GS1 to use EAN-13 barcodes?

If you are selling products through major retailers or marketplaces, yes — you should obtain a GS1 company prefix to ensure your barcodes are globally unique and won't conflict with another manufacturer's products. GS1 registration is available through your national GS1 member organization. For internal use, testing, or development purposes, you can generate EAN-13 barcodes freely without registration.

Can I use EAN-13 barcodes on Amazon and eBay?

Yes. Both Amazon and eBay accept EAN-13 as a valid product identifier for listings. Amazon requires a GS1-registered barcode for most product categories — they cross-check barcodes against the GS1 database and reject listings with unregistered or invalid numbers. eBay is less strict but still recommends using valid EAN codes for better product matching and search visibility.

Final Thoughts

The EAN-13 barcode (or 13 digit barcode) is essential for modern retail and product tracking. Understanding how it works helps you manage products efficiently and ensures compatibility with global systems.
