The Fair Credit Reporting Act (FCRA) is federal regulation enacted to protect consumer information and designates how that information is allowed to be used by consumer reporting agencies (CRA).
A 613 Letter is the notice the CRA sends to the applicant if a potentially negative item was discovered in their background screening report.
As opposed to an adverse letter, a 613 Letter is more of a notification to the applicant that information was discovered during a background check and that information could possibly have a negative impact on their ability to obtain employment. In essence, this letter serves as a "heads-up" notification to the applicant / consumer.
There is a setting under a client's additional settings to indicate that a client is not governed by the FCRA.
If negative information is found on the instant search and follow up searches are not ordered, (not to follow "strict procedures") then they must send the 613 letter and consult their legal counsel on the timing.
The text for the 613a letter can be set under System Settings | Compliance | 613a letter.
