On verified providers. The map draws public demographic and market-orientation data.
A federal registry enumeration (NPPES) tells you an entity exists; it is not licensure,
credentialing, or verification that a provider practises where the record says. Verified
provider intelligence is a separate, in-validation programme — Texas first — and is never
implied by anything on this national map.
