How do last 4 digits of SSN help verify my age?
AgeChecker.Net uses the last 4 digits of your Social Security Number (SSN) to facilitate the verification process. It is very unlikely that anyone else has the same first and last name, date of birth plus the same last 4 digits in their SSN.
Therefore this combination is used as a key to look up your record in the public and government data sources. This is so we can be 100% sure of your identity and age.
