What is an NPI? An NPI is a unique 10-digit identification number used in standard health care transactions. It is issued to health care professionals and covered entities that transmit standard HIPAA electronic transactions (e.g., electronic claims and claim status inquiries).
The Persian people (Persian: Ù¾Ø§Ø±Ø³ÛØ§Ù) are an Iranian ethnic group native to Iran who are native speakers of the modern Persian language, closely related Iranian dialects and languages, and adhere to cultural systems connected with other ethnic Persians.
Persia/Persian is more or less synonymous with Iran/Iranian. Persia is just the older name whereas Iran is the country's modern name. I think people from Iran call themselves Persian because of Iran's negative image in the west since the 1979 revolution.
