The GS1 Parser API is a powerful tool that allows you to parse and validate GS1 barcode data. It accepts both machine-readable and human-readable GS1 logistics barcode content, extracting the encoded information and organizing it into different application identifiers (AI) for further analysis.

GS1 barcodes are globally recognized and standardized barcodes used to encode product information, such as item numbers, batch/lot numbers, expiration dates, and more. These barcodes facilitate efficient supply chain management, inventory control, and product tracking.

The GS1 Parser API validates barcode content and context by verifying that the parsed data conforms to GS1 standards. It checks the structure and syntax of the barcode data, ensuring that the information encoded within the application identifiers (AI) is accurate and properly formatted.

Yes, the GS1 Parser API is designed to handle various types of GS1 barcodes, including GS1-128, GS1 DataBar, GS1 DataMatrix, and more. It supports both linear and 2D barcodes commonly used in logistics and supply chain applications.

Yes, the GS1 Parser API provides additional contextual information for each parsed barcode. This may include data such as the barcode type, encoding standards, and any applicable industry-specific guidelines associated with the barcode.

Zyla API Hub is, in other words, an API MarketPlace. An all-in-one solution for your developing needs. You will be accessing our extended list of APIs with only your user. Also, you won't need to worry about storing API keys, only one API key for all our products is needed.
