CARO by Spherity Documentation

CARO Documentation #


General Introduction #


CARO supports trading partners using a Verification Routing Service (VRS) for Product Identifier Verifications to comply with U.S. Drug Supply Chain Security Act (DSCSA) requirements for Authorized Trading Partners (ATP). To increase patient safety, the DSCSA postulates that pharmaceutical supply chain actors are only permitted to interact with trading partners that are authorized. Manufacturers and repackagers are authorized when they hold a valid FDA registration; wholesalers, third-party logistics providers (3PL), and dispensers require a State-issued license (refer to FDA guidance). Watch this FDA video for an introduction to the topic.

An ATP check on both sides is, for example, required for the verification of saleable returns or suspicious products. A wholesaler or dispenser would use their VRS to route the verification request to the original manufacturer. The manufacturer needs to identify the requester and verify the ATP status before sending a response with the product details. The identification and verification of the authorized status is also required when the requester receives a response from the manufacturer. Hence, both the requester and responder need mechanisms in place to ensure that the other side is an ATP.
