SSN Trace
Due Diligence is one of the first checks that is done for background verification of any gig worker, blue-collar worker, and several other working classes. The sources for such checks can be very diverse and include Federal and State criminal databases, motor vehicle report checks, civil court checks, etc. Signzy has created a global NDD product that has an exhaustive list of sources through which an employer, or any entity can be sure that the person they are going to work with is a trustworthy individual.
As a first step, we have already National Criminal Checks, PEP, Adverse Media & Watchlists checks API required for background verification of the person. Now, the SSN Trace API is used to verify the user's identity and and details associated with the user.
Social Security trace searches are performed with every background check to indicate the name and address history of an applicant. SSN trace will also confirm whether the Social Security number is valid and matches the candidate’s name and address history. SSN trace will give insight to which jurisdictions should be searched. Â
The search is typically the first step and often combined with a NatCrim search to confirm or to indicate potential criminal record history. This information is used as an indicator of potential risk a candidate could pose to an organization.
By searching an SSN, we will provide the name(s), address(es), and phone number(s) associated with that identification number from a variety of sources.
Some important business areas where the SSN Trace API is very helpful are:
Identity Verification:
SSN traces can be used as part of identity verification processes. Verifying a person's details against their SSN can help confirm the accuracy of the information provided.
Fraud Detection:
The API can help detect potential fraud by comparing the provided SSN against databases to identify inconsistencies or discrepancies.
Background Checks:
Employers and organizations can use SSN traces for background checks during the hiring process to validate a candidate's identity and history.
Compliance:
In regulated industries such as finance and healthcare, using SSN traces can help comply with legal and regulatory requirements for customer due diligence and Know Your Customer (KYC) procedures.
Customer Onboarding:
Businesses can streamline customer onboarding processes by using SSN traces to quickly verify identity information provided by customers.
Reduced Errors:
Manual data entry errors can occur when collecting personal information. An SSN trace API can minimize errors by automating the retrieval of accurate details associated with an SSN.
Enhanced Data Accuracy:
The API can provide up-to-date and accurate information about individuals, improving the quality of data in customer databases.
Risk Assessment:
Financial institutions and lending companies can use SSN traces as part of their risk assessment processes to determine an applicant's creditworthiness.
Personalization:
For marketing and customer service purposes, having accurate customer information can enable personalized interactions and communications.
Efficiency:
Instead of manually verifying SSN information, the API allows for quick and automated data retrieval.
You must first login before sending the request. The authorization header in the request must include the access token obtained from the login API call.
