NPI Validation Check Digit Calculation
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 | 8 | 9 | 1 | 5 | 8 | 7 | 8 | 1 | 2 |
| Step 1: Double the value of the alternate digits, beginning with the rightmost digit. | |||||||||
| 2 | 8 | 18 | 1 | 10 | 8 | 14 | 8 | 2 | |
| Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24. | |||||||||
| 2 + 8 + 1 + 8 + 1 + 1 + 0 + 8 + 1 + 4 + 8 + 2 + 24 = 68 | |||||||||
| Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit. | |||||||||
| 70 - 68 = 2 | 2 | ||||||||
The NPI number 1891587812 is valid because the calculated check digit 2 using the Luhn validation algorithm matches the last digit of the original NPI number.
