The Pinnacle Secure Check System

To provide a comprehensive picture of your applicant's criminal history Pinnacle researches the applicant's indentity, all aliases and the locations in which the applicant has lived. This provides names & locations to be searched for criminal and civil records (this is why a legally compliant criminal check MUST include a SSN Trace). Our comprehensive investigation starts with associating the provided social security number (SSN Trace) to the actual applicant rather than relying solely on the applicant to "tell the truth" and provide their aliases and addresses. Our experienced investigators research various databases to independently develop names, aliases and address history and then thoroughly research criminal records for every name and location. Pinnacle researches current criminal records at the local county and state-wide level along with Federal Court checks for a complete picture. 

* Court fees and other associated costs will be in addition to our flat fee.
