Social Security Number Reporting Requirements

Information for UCSB students with Gaucho Health Insurance who have not supplied their Social Security Number (SSN) or Taxpayer Identification Number (TIN) to the UCSB Registrar:

You may receive a letter from the Aetna insurance company asking for your Social Security Number (SSN) or Taxpayer Identification Number (TIN), for the purposes of reporting your compliance with health insurance coverage as mandated under the Affordable Care Act federal legislation (ACA). The law requires that Aetna make three attempts to collect this information from you.

An example of the Aetna letter is posted here along with FAQs. UCSB is not involved in collecting this information, and you should follow the directions in the letter to report your numbers directly to them confidentially.

For any questions about their processes, please call the customer service number on the back of your GHI ID card (855) 821-9712. You can print out your GHI ID card from the Aetna website

The Aetna letter will be sent to the local address you have on file in the UCSB Registrar’s Office. Please be sure to keep this updated in GOLD so that you can receive correspondence from Aetna about your GHI coverage.


The Affordable Care Act (ACA) requires health insurance plans to provide annual verification to the Internal Revenue Service (IRS), that you were covered under a qualified plan during the year. This is because individuals (including students) who are covered under qualified plans for the year will not be subject to tax penalties for failure to have health coverage as required under the ACA.


Certain individuals are exempt from this requirement. You will still receive a statement of coverage but you do not need to provide a SSN.

To see a list of exemptions, go to Q/A 6 of the IRS Questions and Answers on the Individual Shared Responsibility Provision.

The remaining questions and answers at this site provide a good overview of the individual shared responsibility rules under the ACA.
