Identifying Information- Organization- EIN¶

An Employer Identification Number (EIN) is assigned by the Internal Revenue Service (IRS) to identify a business entity. It may or may not be that business entity’s Taxpayer Identification Number (TIN). An SSN should not be entered in the EIN field.

Business Mailing and Practice Addresses¶

The National Provider Identifier (NPI) application requires both a Business Mailing Address and Business Practice Location Address to be listed. The Business Mailing Address can be the same as the Business Practice Location Address if the provider can receive mail at the same location where he/she practices.

Both the Business Mailing Address and Business Practice Location Address are made public via the NPI Registry on the National Plan and Provider Enumeration System (NPPES) and can be updated at any time.

Please keep in mind that the NPI Enumerator is not permitted to advise you of what specific address should be listed within the NPI record. If you have further questions on which address to list, please consult your employer or health plan contractor for further guidance.

Other Provider Identification Numbers¶

Legacy numbers may be entered in the Other Provider Identifiers section of the National Provider Identifier (NPI) application. This section of the application is optional and you are not required to obtain legacy numbers for the purpose of applying for an NPI. The NPI Enumerator encourages Providers to provide this information, but if you are in doubt about whether to include them on your NPI application, please contact the health plans, with which you conduct business, for clarification. You may submit a maximum of 50 Other Provider Identifiers when applying for the NPI.

Taxonomy¶

A taxonomy code is a code that describes the Provider or Organization’s type, classification, and the area of specialization. You will find a complete list of taxonomy codes at https://taxonomy.nucc.org/ . The code set consists of two parts: Individuals plus Groups of Individuals and Non-Individuals.
