Are you unsure if a SSN is valid or do you think a tenant gave you a fake Social Security Number? There a few helpful websites out there to decode social security numbers including one by Steve Morse which by entering the first 5 digits of the person’s social you can find out the state and date range the SSN was issued.
For example I will check the social security number beginning with 421-11-xxxx. I can see the social was issued in Alabama between 1981 and 1982.
If you would like more detailed information and would like to verify if the SSN matches the person’s name and if the SSN is listed as a deceased person you can purchase StarPoint Screening’s SSN Identification Verification Report. SSN ID Verifier searches more than 19 billion public and proprietary records to instantly verify identity based on basic driver’s license information and potentially fraudulent identities.
