The NPI enumerator requires providers to submit at least one taxonomy code. A taxonomy code is a unique 10-character code that describes the healthcare provider type, classification, and the area of specialization. There could be only one primary taxonomy code per NPI record. For individual NPIs the license data is associated to the taxonomy code.
The NPI Enumerator encourages providers to submit additional identifiers with their NPI application although the submission of this information is optional. The additional identifier(s) section includes other numbers or codes currently or formerly used as an identifier for the provider by other public healthcare entities. The identifiers may include UPIN, NSC, OSCAR, DEA, Medicaid State or PIN identification numbers.

The following table explains the step by step NPI number validation process using the ISO standard Luhn algorithm.
| Start with the original NPI number, the last digit is the check digit and is not used in the calculation. | |||||||||
| 1 | 1 | 4 | 4 | 2 | 1 | 8 | 9 | 2 | 6 |
| Step 1: Double the value of the alternate digits, beginning with the rightmost digit. | |||||||||
| 2 | 1 | 8 | 4 | 4 | 1 | 16 | 9 | 4 | |
| Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24. 2184411694 | |||||||||
| 2 + 1 + 8 + 4 + 4 + 1 + 1 + 6 + 9 + 4 + 24 = 64 | |||||||||
| Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit. | |||||||||
| 70 - 64 = 6 | 6 | ||||||||
The NPI number 1144218926 is valid because the calculated check digit 6 using the Luhn validation algorithm matches the last digit of the original NPI number.
