How many digits can the second segment of the NDC contain?

• A. 1-2 digits
• B. 3-4 digits
• C. 2 digits
• D. 5-6 digits

Answer: (B)

The NDC is a three-segment code: the first segment is the labeler (manufacturer), the second is the product code, and the third is the package code. Formats have varied over time, including a 10-digit form like 5-4-1 and an 11-digit form like 5-3-2. Because the middle segment changes to accommodate these formats, it can be either 3 digits or 4 digits. For example, 12345-6789-0 shows a 4-digit middle segment, while 12345-678-90 shows a 3-digit middle segment.
