What Local Education Agency (LEA) covers
The term local education agency means a public board of education or other public authority legally constituted within a State to either provide administrative control or direction of, or perform a service function for public schools serving individuals ages 0 - 21 in a state, city, county, township, school district, or other political subdivision including a combination of school districts or counties recognized in a State as an administrative agency for its public schools. An LEA may provide, or employ professional who provide, services to children included in the Individuals with Disabilities Education Act (IDEA), such services may include, but are not limited to, such medical services as physical, occupational, and speech therapy.

Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 2 | 1 | 5 | 2 | 0 | 4 | 1 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 2 | 2 | 5 | 4 | 0 | 8 | 1 | 1 |
Sum = 49 · next multiple of 10 = 50 · check digit = 1 · actual last digit = 1
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
