Generate random barcode numbers for testing and development purposes. Create valid EAN-13, UPC-A, Code128, Code39 and ITF-14 barcodes with ease.
The Random Barcode Generator allows you to instantly create random barcode numbers for testing, development, and demonstration purposes. This tool supports multiple popular barcode formats including EAN-13, UPC-A, Code 128, Code 39, and ITF-14.
Whether you are building a barcode scanning application, testing inventory systems, or demonstrating barcode functionality, this random bar code generator can save time and simplify the process. You may also see it referred to as a barcode random generator — either way, it produces valid, scan-ready barcodes instantly.
With this tool, you can generate random barcode numbers and view them as both text and barcode images.
Using this tool is simple and requires only a few steps:
The generated barcodes will appear instantly on the page.
EAN-13 is the most widely used retail barcode standard worldwide, consisting of 13 digits including a check digit. This random EAN-13 generator creates valid EAN-13 barcode numbers instantly, making it ideal for testing POS systems, inventory software, and barcode scanners. Each randomly generated EAN-13 barcode follows the correct GS1 structure and includes a valid check digit, so it will scan correctly in any EAN-13 compatible reader.
Use this random EAN-13 barcode generator when you need sample product codes for development environments, QA test suites, or retail software demonstrations — without using real registered GS1 numbers.
UPC-A is the standard 12-digit barcode format used across North America for consumer retail goods. This random UPC code generator produces valid UPC-A barcodes with a correctly calculated check digit, suitable for testing barcode scanners, point-of-sale systems, and inventory applications.
Whether you need a single random UPC number or a batch of random UPC codes for bulk testing, this random UPC generator saves time by producing scan-ready barcode images alongside each generated number. Note that these are test values only — for real product registration you need a licensed GS1 UPC prefix.
UPC-A is a 12-digit barcode commonly used in North America for consumer goods. It is one of the most recognizable barcode formats in retail environments.
Code 128 is a high-density barcode format that supports alphanumeric characters. It is widely used in shipping, logistics, and inventory management systems.
Code 39 is one of the earliest barcode formats that supports letters, numbers, and a few special characters. It is commonly used in industrial and automotive industries.
ITF-14 barcodes are primarily used for packaging and shipping cartons in warehouses and supply chains.
Generating random barcode numbers can be useful in many situations:
Developers often need sample barcode values when building POS systems, warehouse management software, or barcode scanning applications.
Random barcode images can be used to test barcode scanners and mobile scanning applications.
Quality assurance teams use random barcode numbers to simulate product data during testing.
Random barcode samples are helpful for training employees or demonstrating barcode technology.
