CMS PROVIDER REFERENCE
National NPI directory
Search the preserved national provider registry by NPI or the beginning of a provider’s name. This directory is separate from the disability-practitioner census.
NPI registration does not verify licensure, credentials, a current physical office, or membership on an SSA medical or vocational expert roster.
Checking the available registry snapshot…
Names are searched as stored: organizations by organization name; individuals by first name, optional middle name, then surname. Use the exact NPI to distinguish providers with similar names.
Sources and interpretation
Addresses, taxonomies, and dates are provider-registry records. An address may have changed since the source snapshot. Deactivation information is retained separately with its own date.
