Social Security Number (SSN) Trace

This article will help you:

• Understand what a SSN Trace is and why it’s an important part of a background report
• Follow Checkr's SSN Trace process
• Understand your candidate's experience

A Social Security Number (SSN) Trace searches databases (including lending institutions, utilities, schools, and credit card companies) for a name and Social Security Number. The trace returns jurisdictions in which a match is found, and may report any alternative names (aliases or AKAs) that are identified as well.

To run an SSN Trace, Checkr submits the candidate's Social Security Number to a data provider, who then generates a report through a credit bureau. This report returns a list of known names and addresses for the SSN, compiled from credit and banking history for the given SSN.  

SSN Traces are used as a “pointer” to possible criminal records. The address and alias information that the SSN Trace returns is then used to determine which counties and other databases should be searched for additional public records (if your package is configured to include aliases).

The SSN Trace may provide the following information:

• An idea of whether the SSN provided is a valid or invalid number (for example, whether it has any names associated with it.
• If your package configuration includes aliases, a list of previous names (which may be birth names as well as aliases).
• Locations the person linked to the number has lived (based on credit cards, banking, or other information).

An SSN Trace does not validate that the person entering the information is who they claim to be. An SSN Trace can identify whether the candidate’s SSN appears to be false (such as 555-55-5555), but an SSN Trace is not an Identity Verification. For more information, please see SSN Traces vs. Identity Verification.

Please note: 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

Checkr's product incorporates SSN field controls designed to not accept SSNs with the following characteristics:

• SSNs without exactly 9 numeric characters
• SSNs that start with 666 (666-34-3768)
• SSNs that start with 9 (967-65-4325)
• SSNs that are a single repeated digit (111-11-1111)
• SSNs that are sequential digits (123-45-6789)

Candidate Experience

The SSN Trace is included in Checkr’s basic report package, which includes SSN Trace, Sex Offender Registry Check, Global Watchlist Records Check, and National Criminal Records Check. The SSN Trace cannot be run as a standalone Check.

Candidates will be asked to provide Personally Identifiable Information (PII), including their full name, date of birth, social security number, email address, and phone number.

They will then be presented and asked to acknowledge receipt of applicable forms and notifications, including Summary of Your Rights Under the Fair Credit Reporting Act (FCRA) and an Acknowledgement and Authorization for Background Check.

After the candidate consents, Checkr will initiate the Trace.

If we are unable to complete the SSN Trace with the information provided, the candidate will be asked to re-enter their number. In some cases, candidates may be asked to provide a copy of their SSN card, or a letter from the SSA confirming that the number provided does belong to the candidate.
