NVIDIA created an alternate ID number to use in place of your SSN. This alternate ID number can be used to identify you in any of the Cigna plans for medical and mental health services, Delta Dental, and VSP vision plans. The formula for your alt ID is: 81 + your 2-digit year of birth + your NVIDIA badge number (up to 5 digits). If your NVIDIA badge number is less than 5 digits, simply precede it with enough zeroes to create a full 9-digit number.
For example, John’s birth year was 1978, and his employee badge number is 6852. His alt ID is: 81 + 78 + 06852 = 817806852.
