What is the Barcode Checksum Calculator?

The Barcode Checksum Calculator is a tool that computes the final checksum digit for barcodes such as UPC-A and EAN-13. The checksum is used to verify the accuracy of the barcode and prevent scanning errors. By entering the barcode digits without the checksum, the calculator instantly determines the correct final digit, making it useful for retailers, manufacturers, and anyone generating or verifying barcodes.

How to Use:

1. Enter Barcode Digits: Type the numeric digits of the barcode without the checksum, for example, 03600029145.
2. Click “Calculate”: The calculator processes the digits and applies the checksum formula.
3. Review the Result: The correct checksum digit appears in the result box, ensuring your barcode is valid and ready for scanning.
