DSCSA Aggregation 2023 Compliance and Implementation

Learn about the requirements

What is aggregation?

Aggregation is the association of uniquely serialized items to higher packaging levels, which also have a unique serial number. The serialized items inside a container are known as the “children,” and the serialized container containing these packs is called the “parent.” In a bundle of bottles or cartons, each unit has its own serial number, but the bundle itself has a top label including a unique serial number. In this case, the bottles or cartons are the children, and the bundle itself is the parent.

In short, aggregation is the process of creating a hierarchical relationship between unique identifiers assigned to packaging containers.



In the United States, the Drug Supply Chain Security Act (DSCSA) made item-level serialization mandatory in November 2018. Thanks to this legislation, more and more companies are starting to see the value and potential return on investment of serialization and compliance.

Although aggregation is only expected to become mandatory and fully applied in 2023, according to the U.S. FDA (Food and Drug Administration), it is more realistic to say that most manufacturers, along with the top pharmaceutical companies, will be ready well before the deadline, or have already implemented an interoperable track-and-trace system along with their serialization. This global transparency will prevent counterfeit and fraudulent products from entering the improved healthcare supply chain, therefore ensuring the safety of patients worldwide and creating trust in the pharmaceutical industry.

Implementation in the Pharma Industry

Some of the biggest pharma companies already fully implemented aggregation at the same time as serialization, since they knew it would be worth the effort, i.e., improved inventory, rework, and recall process management, among others.

Manufacturers who had only implemented serialization in order to quickly comply with the statutory serialization requirements now need to carefully plan the implementation of aggregation in their facilities. Although the process may be one you are not looking forward to, it is important to keep in mind that aggregation presents numerous long-term benefits.


The aggregation process is meant to facilitate and benefit everyone involved in the supply chain, from the production of medications, all the way to the end consumer. First, the new requirements make it extremely easy to rework packages, meaning that all necessary and important information about the medications will be accessible when scanning the parent. This saves an enormous amount of time, as it will no longer be necessary to open each container to scan each individual child. Since all the data is easily accessible, tracking products throughout the supply chain becomes much easier, and the entire distribution system becomes more efficient, secure and trustworthy.
