NPI Validation Check Digit Calculation
The following table explains step by step the NPI validation process using the Luhn algorithm:
| Start with the original NPI number, the last digit is the check digit and is not used in the calculation. | |||||||||
| 1 | 4 | 0 | 7 | 8 | 7 | 8 | 2 | 7 | 5 |
| Step 1: Double the value of the alternate digits, beginning with the rightmost digit. | |||||||||
| 2 | 4 | 0 | 7 | 16 | 7 | 16 | 2 | 14 | |
| Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24. | |||||||||
| 2 + 4 + 0 + 7 + 1 + 6 + 7 + 1 + 6 + 2 + 1 + 4 + 24 = 65 | |||||||||
| Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit. | |||||||||
| 70 - 65 = 5 | 5 | ||||||||
The NPI number 1407878275 is valid because the calculated check digit 5 using the Luhn validation algorithm matches the last digit of the original NPI number.
