FDA is reminding the medical device industry and unique device identifier (UDI) stakeholders that the 5/2021 guidance on enforcement policy regarding the use of National Health Related Item Code and National Drug Code numbers on device labels and packages applies only to devices labeled before 9/24/23\. An agency [notice](https://content.govdelivery.com/accounts/USFDA/bulletins/332ef81?ref=fdaweb.com) says that devices labeled on or after 9/24/23 must comply with all applicable UDI requirements, including the prohibition on using certain legacy FDA identification numbers (National Drug Code and National Health Related Item Code) on the label.

To help stakeholders prepare, the notice says, the agency is posting frequently asked questions (FAQs) to its Web site. It also is posting FAQs on universal product code (UPC) alternatives. These time-limited alternatives also end on 9/24/23.
