Are immigrants with an ITIN allowed to use it instead of an SSN on their Pennie application?

Immigrants with an Individual Taxpayer Identification Number (ITIN) are not permitted to use it in place of a Social Security Number (SSN) on their Pennie application. The requirement is to provide a valid SSN for individuals applying for health coverage through the marketplace. The use of an SSN is crucial for identifying applicants and ensuring they are eligible for specific benefits, tax credits, and subsidies available under the Affordable Care Act. An ITIN is used primarily for tax purposes and does not serve the same identification purposes in the context of health insurance applications. Therefore, individuals must have a valid SSN to fill out a Pennie application accurately.
