This document specifies requests and responses for Verification of Product Identifiers, especially for pharmaceuticals. In health care, a combination of the Global Trade Item Number (GTIN) and Serial Number is often used to create a unique product instance identifier, and the Lot or Batch Number and Expiry Date are included as data attributes of that identifier. This standard is intended to provide a simple standardised lightweight messaging framework to define verification questions and corresponding responses to enable decisions to accept, reject or quarantine a product instance, based on the authentication check of the product identifier and associated data.

Main sections:

• Verification of Product Identifiers for pharmaceuticals
