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 | 9 | 6 | 2 | 4 | 0 | 7 | 8 | 9 | 0 |
| Step 1: Double the value of the alternate digits, beginning with the rightmost digit. | |||||||||
| 2 | 9 | 12 | 2 | 8 | 0 | 14 | 8 | 18 | |
| Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24. | |||||||||
| 2 + 9 + 1 + 2 + 2 + 8 + 0 + 1 + 4 + 8 + 1 + 8 + 24 = 70 | |||||||||
| Step 3: because the number obtained in step 2 ends in zero, the check digit is zero. | |||||||||
| 0 | |||||||||
The NPI number 1962407890 is valid because the calculated check digit 0 using the Luhn validation algorithm matches the last digit of the original NPI number.
