How to update your Tax Identification Number (TIN)

 

You can now update your TIN through the Provider Onboarding Center (POC) via Aetna.com.

 

You asked, we listened

 

Based on your feedback, we created an online form that you can use to submit TIN changes. This form will decrease processing time. Please use it if you need to update a TIN.

 

What you will need to complete the form

 

  • Your new TIN. If you are updating multiple TINs, you will need to complete a separate form for each one.
  • Your National Provider Identification (NPI) number
  • A valid and complete W-9 associated with the new TIN (file size cannot exceed 2 MB)
  • A current list of all service locations

Upon submitting the form, you will receive a pop-up confirmation and the request ID number, which you should keep for your records.

 

Benefits of using the form

 

  • Quicker turnaround time
  • Less follow-up work because all information is gathered up front
  • Real-time confirmation of your request, including a request ID number for easy identification
