Specialty - Primary Taxonomy

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.

Classification: Contractor
Taxonomy Code: 171W00000X
Type: Other Service Providers
License No.: 08-0008
License State: NV
Taxonomy Description: For the purposes of the Health Care Provider Taxonomy, a contractor is limited to individuals who do construction or mechanical work to modify a patient's environment to accommodate a health condition. Contractors perform projects including, but not limited to, building wheelchair ramps, widening doorways, modifying personal vehicles, and making other improvements for patient access and movement. This code has no relation to a provider's employment status.

NPI NPI Number Validation

How NPI Validation Works

The NPI validation process uses the ISO-standard Luhn algorithm, a mathematical "handshake", to ensure that a provider's 10-digit ID is authentic and free of common typing errors.

To verify the NPI 1639362882, we treat the final digit (2) as the Check Digit—the target answer we need to reach. The process begins by taking the first nine digits and adding a constant value of 24, which accounts for the "80840" prefix required for all U.S. health identifiers. We then double every other digit starting from the right and sum the individual digits of those results together. For this specific NPI, that total comes to 78. The final step is to find the difference between that total and the next multiple of ten (80 - 78 = 2).

Digit-by-digit view

Use the first nine digits for the calculation. Starting from the right, double every other digit. The last digit is the check digit and is not part of the calculation.

Regular digit Doubled digit Check digit

Step 1: Double every other digit from the right

Starting with the rightmost digit of the first nine digits, double every other value. If doubling creates a two-digit number, add those digits together.

1 → 2 3 → 6 3 → 6 2 → 4 8 → 16 → 7

Step 2: Add all digits plus the NPI constant

Add the transformed values, the unchanged digits, and the constant 24.

2 + 6 + 6 + 9 + 6 + 6 + 4 + 8 + 1 + 6 + 24 = 78

Step 3: Find the amount needed to reach the next multiple of 10

The next multiple of ten after 78 is 80. The difference is the calculated check digit.

80 - 78 = 2

This NPI is valid

The calculated check digit is 2, which matches the last digit of 1639362882.
