Your Social Security number (SSN) is a unique way to identify you, which makes it key to locating your credit files.
In most cases, the last 4 digits of your SSN, along with the other personal information you enter, will be enough to match your identity with your Equifax and TransUnion credit files. In some cases, though, we may need your full SSN to ensure a correct match.
Rest assured that we’re committed to keeping your info safe. If you have any concerns about the security of your information, check out our security page.
Can I use my Tax Identification number to register?
We cannot accept an Individual Tax Identification number (ITIN). Credit Karma is only available to U.S. residents with a Social Security number.
