What is a UPC-A barcode?

UPC-A barcodes are used in retail where products require a unique identification number for easy scanning and inventory tracking. While UPC-A is effective for products that don’t need to encode complex data, it is limited in terms of data capacity compared to 2D barcodes like QR codes or Data Matrix, which can store much more information.

How much data can a UPCA barcode hold?

A UPC-A barcode can hold exactly 12 numeric digits. It is designed to encode only numeric data, meaning it can store digits from 0 to 9, without the ability to hold letters or special characters.
