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.

Taxonomy Code: 106E00000X
Type: Behavioral Health & Social Service Providers
Taxonomy Description: An assistant behavior analyst is qualified by Behavior Analyst Certification Board certification and/or a state-issued license or credential in behavior analysis to practice under the supervision of an appropriately credentialed professional behavior analyst. An assistant behavior analyst delivers services consistent with the dimensions of applied behavior analysis and supervision requirements defined in state laws or regulations and/or national certification standards. Common services may include, but are not limited to, conducting behavioral assessments, analyzing data, writing behavior-analytic treatment plans, training and supervising others in implementation of components of treatment plans, and direct implementation of treatment plans.

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 1487510053, we treat the final digit (3) 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 47. The final step is to find the difference between that total and the next multiple of ten (50 - 47 = 3).

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 8 → 16 → 7 5 → 10 → 1 0 → 0 5 → 10 → 1

Step 2: Add all digits plus the NPI constant

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

2 + 4 + 1 + 6 + 7 + 1 + 0 + 1 + 0 + 0 + 1 + 0 + 24 = 47

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

The next multiple of ten after 47 is 50. The difference is the calculated check digit.

50 - 47 = 3

This NPI is valid

The calculated check digit is 3, which matches the last digit of 1487510053.
