Type 2 Organization Provider
A health care provider that is an organization, such as a group practice or corporation. Individual dentists who are incorporated may enumerate as Type 2 providers, in addition to being enumerated as a Type 1. All incorporated dental practices and group practices are eligible for enumeration as Type 2 providers.
On paper, there is no way to distinguish a Type 1 from a Type 2 in the absence of any associated data; they are identical in format. Additional information on NPI and enumeration can be obtained from the ADA’s Internet Website: http://www.ada.org/goto/npi.
