Revalidating Your Enrollment

Prevent Revalidation Processing Delays

When National Government Services receives a revalidation application, we often determine additional information is needed to process the application. In those cases, a request for additional information is sent which is commonly referred to as development. Sending development requests and waiting for responses delay processing times.

One way to prevent a common delay is by ensuring you meet the name matching requirements before submitting an application:

For Who Requirements
For Individuals and Individual Sole Proprietors enrolled under a SSN or an EIN, the legal name reported on enrollment applications, EFT agreements and all of these sources must match exactly

Note: If you have employees, an EIN is required
  • The individual’s legal name reflected in Social Security records
  • The individual’s legal name reflected in the NPPES Registry for the Type 1 NPI
  • The individual’s legal name reflected on a voided check or bank confirmation letter when applicable
  • The individual’s legal name reflected in the IRS record as demonstrated by an IRS-CP575, IRS-147C or other approved form (if enrolled under an EIN) and this must match the individual’s legal name in Social Security records
For Individuals Who are Sole Owners of an Organization, the individual’s legal name and Legal Business Name reported on enrollment applications, EFT agreements and all of these sources must match exactly
  • The individual’s legal name reflected in Social Security records
  • The individual’s legal name reflected in the NPPES Registry for the Type 1 NPI
  • The organization’s legal business name reflected in the NPPES Registry for the Type 2 NPI
  • The organization’s legal business name on a voided check or bank confirmation letter
  • The organization’s legal business name reflected in the IRS records as demonstrated by an IRS-CP575, IRS-147C or other approved form

The table below contains the top reasons for development and how to prevent them. Using PECOS to submit your revalidation application can also help prevent development requests since you are verifying information already on file rather than fully completing a blank paper application.
