COVID-19 Vaccine Lot Number and Expiration Date Files Now Available

Registered users can now access COVID-19 vaccine lot numbers and expiration dates provided to CDC by the vaccine manufacturer from downloadable tabular files for use in vaccine administration, inventory management, and jurisdictional immunization information systems. These files will contain all lots for COVID-19 vaccines made available under Emergency Use Authorization (EUA) for distribution in the United States. The files include the manufacturer, the National Drug Codes (NDCs) for Unit of Sale (boxes/cartons) and Unit of Use (vials) for each lot number, and the manufacture date and expiration date.

Files will be updated on a daily basis Monday through Friday as new lots are released by each manufacturer, or as updates are made to the lot expiration dates. Please note that as manufacturers confirm their product stability data, some expiration dates may be updated.

How do I register to request access to lot number and expiration date files?

Access to lot number and expiration date information is controlled for security reasons. To request access to the lot number and expiration date data files, complete the registration page, acknowledge the terms and conditions for access and use of the data, and create a password. We will evaluate your request and send the registration approval decision within 48 hours to the email address you provided during registration. If approved, the email will include a link and instructions for accessing the files.

How can these files help improve data quality and processes?

Correctly entered lot number and expiration date data improve the ability to monitor product safety, identify issues with lots, trace or decrement inventory, and identify expired product that may not have been administered. The vials and cartons for COVID-19 vaccines authorized under EUAs are not 2D barcoded following the standards used for products licensed by the US Food and Drug Administration, so lot number and expiration dates may not be scanned into systems. Lot information must be entered manually in many cases, which increases the risk for errors and omissions in the reported data.

The Centers for Disease Control and Prevention (CDC) encourages systems to use these new files as a reference that can be integrated into workflows to assist in capturing and validating lot number and expiration date information. Manufacturers will continue to provide QR codes on their products that link to their sites, where individual lot expiration dates can be looked up.
