Checkr SSN Trace API is one of 56 APIs that [Checkr](https://apis.io/providers/checkr/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include SSN Trace. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

SSN Trace is typically the first screening run, and is used to verify that the input SSN exists, determine where and when it was issued, and to compile a list of all known aliases associated with the SSN. This Trace is also used to generate a list of all known addresses recorded by credit agencies for the SSN for the last 7 years. An SSN Trace may be used to determine which additional jurisdictions should be searched for the candidate, based on the list of known addresses returned. If the platform detects an issue with the SSN Trace run (data mismatch, absence of data, or inclusion of the SSN on the death master file), Checkr may issue an exception and ask the candidate to either re-enter their SSN or upload other supporting documentation. <b>Note: </b>Information returned by this search is not a part of the consumer report and may not be used for FCRA purposes, including eligibility determinations under the FCRA For more information, please see [SSN Trace](https://help.checkr.com/hc/en-us/articles/360001967227) in the Checkr Help Center.
