What is an IRS Number?
The term "IRS Number" can indeed be puzzling because it doesn’t refer to a single, specific number. Instead, it is a broad term that could refer to any number of tax identification numbers issued or used by the Internal Revenue Service (IRS) to manage various types of accounts and records. Here are the most common types of identifiers you might hear referred to when someone mentions an IRS number:
- Social Security Number (SSN): Assigned to individuals, it's the most common taxpayer identification number.
- Employer Identification Number (EIN): Used by businesses, trusts, and estates.
- Individual Taxpayer Identification Number (ITIN): For individuals who are not eligible for an SSN.
- Preparer Tax Identification Number (PTIN): Used by paid tax return preparers.
Now, let’s explore each of these identifiers in more detail to understand their unique roles and how they serve taxpayers.

For many individuals in the U.S., the SSN serves as the primary federal tax identification number and is required for most financial transactions.
Why Is It Important?

Protecting Your SSN
Your SSN is a unique identifier, and protecting it is critical. Here are a few tips to safeguard your SSN:
- Avoid carrying your card: Keep your Social Security card in a safe place and not in your wallet.
