Quick Answers
Common Questions About NDC12
Get concise answers to common questions about the FDA’s 12-digit National Drug Code format, including the 6-4-2 structure, implementation dates, NDC10 conversion, NDC11, labeling, and organizational readiness.
What is NDC12?
NDC12 is the FDA’s uniform 12-digit National Drug Code format. It uses a fixed 6-4-2 structure consisting of a six-digit labeler code, four-digit product code, and two-digit package code.
When does NDC12 take effect?
The final rule takes effect on March 7, 2033. FDA will begin assigning new NDCs in the 12-digit format and converting previously assigned FDA NDCs to the new structure on that date.
What does the 6-4-2 structure mean?
The first six digits identify the labeler, the next four identify the product, and the final two identify the package size and type.
Does NDC12 replace NDC11?
The FDA final rule changes FDA-assigned NDCs. It does not itself revise the separate HIPAA transaction standards that currently use an 11-digit NDC representation for reimbursement.
Who should prepare for NDC12?
Organizations that assign, store, exchange, display, print, scan, validate, or otherwise process FDA-assigned NDCs should assess their readiness.
