What Mail Order Pharmacy covers
A pharmacy where pharmacists compound or dispense prescriptions or other medications in accordance with federal and state law, using common carriers to deliver the medications to patient or their caregivers. Mail order pharmacies counsel patients and caregivers (sometimes independent of the dispensing process) through telephone or email contact and provide other professional services associated with pharmaceutical care appropriate to the setting. Mail order pharmacies are licensed as a Mail Order Pharmacy in the state where they are located and may also be licensed or registered as nonresident pharmacies in other states. NUCC Health Care Provider Taxonomy, code 3336M0002X
The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
Full NPPES record
An NPI-2 identifies an organization — a clinic, hospital, group practice, laboratory, or supplier. Individual clinicians working there hold their own NPI-1 numbers separately, so a bill may reference both.

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 | 6 | 4 | 9 | 3 | 5 | 2 | 0 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 8 | 9 | 6 | 5 | 4 | 0 | 0 |
Sum = 64 · next multiple of 10 = 70 · check digit = 6 · actual last digit = 6
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.
