EAN Generator

What Is an EAN Generator?

An EAN generator creates EAN-13 formatted product identification numbers using the EAN-13 checksum calculation. EAN-13 numbers contain 13 digits, with the final digit acting as a check digit used to verify that the preceding number has been entered correctly.

This free EAN generator can be useful for software development, testing, demonstrations, database development, mock product catalogues and other situations where correctly formatted EAN-13 values are required. Generated values should not be treated as officially assigned commercial product identifiers.

Why Use the EAN Generator?

The tool performs the EAN-13 checksum calculation automatically, allowing you to create correctly formatted numbers without manually calculating the final check digit.

How to Use the EAN Generator

Generating EAN-13 formatted numbers takes only a few seconds.

1. Choose a prefix — Optionally enter up to 12 starting digits if you want the generated numbers to use a particular prefix.
2. Select the quantity — Choose how many EAN-13 numbers you want to generate, from 1 to 50.
3. Generate the numbers — Select Generate EAN Numbers to create the requested values and calculate their check digits.
4. Copy the results — Copy an individual number or use Copy All to copy the complete generated list.

Generate EAN-13 Numbers Online

EAN-13 is a 13-digit product identification format widely associated with retail products and international supply chains. The first 12 digits contain the main identifier and the thirteenth digit is a calculated check digit. The check digit provides a way to detect certain data-entry or transmission errors.

This online EAN generator produces numbers that follow the EAN-13 checksum algorithm. It can therefore be used when a project needs syntactically valid EAN-13 values for testing, prototypes, examples, software development or sample product records.

How the EAN-13 Check Digit Works

To calculate the EAN-13 check digit, the first 12 digits are processed using alternating weights of 1 and 3. The resulting values are added together, and the digit required to make the total divisible by 10 becomes the thirteenth digit. This allows the completed 13-digit number to pass the standard EAN-13 checksum calculation.

EAN Numbers and GTINs

EAN-13 numbers are part of the broader GS1 Global Trade Item Number system and are commonly referred to as GTIN-13 values. A mathematically valid number is not necessarily an officially assigned product identifier. Businesses selling products through retail systems should obtain and use officially assigned GTINs rather than relying on randomly generated numbers.

EAN Generator Information

The generator operates entirely within your web browser. No account, software installation or server-side processing is required. The generated numbers are produced locally when you select the generate button.

The optional prefix accepts numeric digits only. If fewer than 12 digits are supplied, the remaining digits are generated automatically before the EAN-13 check digit is calculated. If no prefix is provided, the first 12 digits are generated automatically.

Generated EAN-13 values should be regarded as test or example identifiers unless you have an appropriate legitimate assignment for the number. The tool does not check whether a generated number has already been assigned to a real product.
