The Social Security Number Verification Service (SSNVS) allows employers to match their record of employee names and Social Security numbers (SSNs) with Social Security records before preparing and submitting Forms W-2. Making sure names and SSNs on the W-2 match our records is important because unmatched records can result in additional processing costs for you and uncredited earnings for your employees. Uncredited earnings can affect future eligibility to (and amounts paid under) Social Security's retirement, disability and survivors program.
SSNVS should only be used for the purpose for which it is intended.
Social Security will verify SSNs and names solely to ensure the records of current or former employees are correct for the purpose of completing an Internal Revenue Service Form W-2 (Wage and Tax Statement). A current employee is defined as a person who has received and accepted a job offer.
It is illegal to use the service to verify SSNs of potential new hires or contractors or in the preparation of tax returns.
Company policy concerning the use of SSNVS should be applied consistently to all workers; for example:
- If used for newly hired workers, verify information on all newly hired workers.
- If used to verify information on other workers in your database, verify the information for all workers in the entire database.
Third-party use of SSNVS is strictly limited to organizations that contract with employers to either handle the wage reporting responsibilities or perform an administrative function directly related to the annual wage reporting responsibilities of hired employees. It is suggested that contracts between the third-party and the employer stipulate that the functions being performed by the third-party contractor relate to wage reporting responsibilities and SSNVS should only be used for the wage reporting responsibilities of hired employees. It is not proper to use SSNVS for non-wage reporting purposes, such as identity, credit checks, mortgage applications, etc.
Anyone who knowingly and willfully uses SSNVS to request or obtain information from Social Security under false pretenses violates Federal law and may be punished by a fine, imprisonment or both.
Social Security may ban you and/or the company you represent from the use of SSNVS if Social Security determines there has been misuse of the service.
SSA returns all names and SSNs submitted. If the name and SSN do not match our records, SSA advises the following:
- This response does not imply that you or your employee intentionally provided incorrect information about the employee's name or SSN.
- This response does not make any statement about your employee's immigration status.
- This response is not a basis, in and of itself, to take any adverse action against the employee, such as laying off, suspending, firing, or discriminating against the employee.
Do not use SSNVS before hiring an employee.
- While the service is available to all employers and third-party submitters, it can only be used to verify current or former employees and only for wage reporting (Form W-2) purposes.
- Social Security will review usage of SSNVS to ensure that employers are using it for the proper purposes.
Do not use SSNVS to take punitive action against an employee whose name and SSN do not match Social Security's records.
- A mismatch does not imply that the employer or the employee intentionally provided incorrect information.
- A mismatch does not make any statement about an employee's immigration status and is not a basis, in and of itself, for taking any adverse action against an employee. Doing so could subject you to anti-discrimination or labor law sanctions.
Third-party use of SSNVS is strictly limited to organizations that contract with employers to either handle the wage reporting responsibilities or perform an administrative function directly related to annual wage reporting responsibilities of hired employees.
It is not proper to use SSNVS for non-wage reporting purposes, such as identity, credit checks, mortgage applications, etc.
