Inspired by the potential of the web and the success of NetDay, VolunteerMatch.org was launched on April 25, 1998, as a merger between Impact Online, Inc.

In 1999, it was promoted by Oprah Winfrey on her show.

The organization's growth has also been spurred by an increased interest in disaster-related volunteering and service following natural and man-made disasters,^{[citation needed]} including the September 11 attacks, Hurricane Katrina, and the 2010 Haiti earthquake. Following Hurricane Katrina, it began a partnership with the American Red Cross to integrate VolunteerMatch's Business Solutions with the Red Cross volunteer opportunity search system.^[12]

VolunteerMatch.org has been cited by three U.S. Presidents as a useful resource for civic engagement. During an August 31, 2002 radio address eight months after the 9/11 attacks, George W. Bush said, "The response to the call to service has been strong. VolunteerMatch, a group that matches volunteers to charities on the USA Freedom Corps web page, reports that referrals have increased by more than 70 percent over last year."^[30] In GIVING: How Each of Us Can Change the World, President Bill Clinton cited VolunteerMatch as a resource for "Giving Time."^[31] And in a January 1, 2008 platform statement on service and volunteering, President Barack Obama wrote, "Technology can help. Existing sites like USAFreedomCorps.gov and VolunteerMatch.org represent a good start."^[32]

VolunteerMatch provides some services similar to those of UK-based Worldwide Helpers, though the latter organization focuses only on projects that are low-cost to the volunteer.
