The Service Members’ Service Relief Act website allows users to search for and verify people on active duty with the US military.
Users of the website can input required information about a person and search the military personnel database. The website will return a “certificate” stating whether or not the Defense Manpower Data Center has information showing the searched person is currently serving on active duty in the US military. There is no fee for the personnel searches.
The Defense Manpower Data Center returns back the personal information entered into the query form by the user; no other personal data on the individual is provided on the certificate.
You can search for people on the Defense Manpower Data Center website at: Defense Manpower Data Center People Search.
For more detailed information on doing a people search on the DMDC site, please see their help page.
