NDC Toolkit
Professional NDC conversion tools, FDA drug lookups, and open-source SDKs for the pharmaceutical supply chain. Built for the NDC12 transition.
Comprehensive NDC Tools
Everything you need to work with National Drug Codes — from format conversions to FDA data lookups and developer integrations.
Convert Any NDC Format
Seamlessly convert between all NDC formats including the upcoming NDC12 standard. Our converter handles NDC10 (4-4-2, 5-3-2, 5-4-1), NDC11 (HIPAA 5-4-2), NDC12 (FDA 6-4-2), and GTIN-14 with full step-by-step conversion logic.

Search FDA DirectoryThe NDC12 Transition
FDA's final rule (March 2026) transitions all NDCs to a uniform 12-digit format by 2033. Here are the key milestones.
Final Rule Published
FDA publishes the NDC12 final rule. 7-year preparation window begins.
NDC12 Effective
FDA begins issuing 12-digit NDCs. All existing NDCs auto-converted to 6-4-2.
Transition Period
3-year window where 10-digit labels are tolerated. Dual-format support required.
Enforcement
Full enforcement begins. All products must use 12-digit NDC labeling.
Developer SDKs & APIs
Integrate NDC conversions into your systems with our open-source libraries. Available in Python, JavaScript/TypeScript, Java, C#, Go, and Ruby — all with comprehensive test suites and documentation.
