A provider’s legal business name is the name that is registered with the IRS and should appear on IRS documents, such as the CP-575, that contains a provider’s EIN or TIN.
The provider’s legal business name with the IRS should identically match (including any or no punctuation) the business name registered with the National Plan & Provider Enumeration System (NPPES), which issues the NPI. This is the information that will be loaded into the PECOS.
To validate that the legal business name the IRS has for you matches the business name registered with NPPES visit the NPPES website or contact them at 1-800-465-3203 or 1-800-692-2326 for TTY services.
