More than 500,000 companies are using E-Verify, the free online service that allows United States employers to confirm their new employees’ eligibility to work.

Employers who use E-Verify receive a response on an employee’s work authorization status within seconds. 98.8 percent of work-authorized employees are automatically confirmed instantly or within 24 hours, requiring no further employee or employer action. Users gave E-Verify a score of 86 out of 100 on the 2012 American Customer Satisfaction Index (ACSI) survey. 

USCIS works with other agencies to allow for increased accuracy.  These efforts have led to E-Verify agreements with select states' departments of motor vehicles to ensure the authenticity of driver's licenses that employees use as identity documents; the introduction of Self Check, which allows workers to look up their own employment eligibility status and correct their records before they seek employment; and a program that combats identity fraud by locking Social Security numbers suspected of being misused for employment eligibility verification.

E-Verify has experienced significant growth since its establishment in 1996. Annual enrollments increased tenfold during the program’s first 16 years, from 11,474 in fiscal year (FY) 1996 to 111,671 in FY 2012. During FY 2013, employers used E-Verify more than 25 million times.

USCIS has released "E-Verify for Business Leaders ," a new video that introduces the program’s benefits to prospective users. USCIS has also launched an updated http://www.uscis.gov/e-verify that has more plain-language content and easy-to-follow graphics.
