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.|
|Step 1: Double the value of the alternate digits, beginning with the rightmost digit.|
|Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.|
|2 + 0 + 0 + 3 + 0 + 0 + 1 + 2 + 3 + 1 + 4 + 24 = 40|
|Step 3: because the number obtained in step 2 ends in zero, the check digit is zero.|
The NPI number 1003006370 is valid because the calculated check digit 0 using the Luhn validation algorithm matches the last digit of the original NPI number.
