Example of 5-4-2 Format
| Package NDC | NDC to submit (Missing zero) |
| xxxx-xxxx-xx (4-4-2) | 0xxxx-xxxx-xx (5-4-2) |
| xxxxx-xxx-xx (5-3-2) | xxxxx-0xxx-xx (5-4-2) |
| xxxxx-xxxx-x (5-4-1) | xxxxx-xxxx-0x (5-4-2) |
Another example:
- Bottle/invoice says 1234-5678-90. This is a 4-4-2.
- The section that doesn't fit the 5-4-2 submitting format is the first number section because it only contains four numbers.
- A zero is placed at the beginning of that section, creating the correct 01234-5678-90.
