Recall the location or the state and year in which you took the GED exam. If you can't remember, call some of your friends or family members. Trace back old resumes and job related documents to find hints on where you took and passed the GED exam.
Go to the US Department of Education website and search "GED." Most of the state education departments process requests for duplicate GED certificates. Some states require you to mail in the application and a fee for this process. The application can usually be downloaded online. Some states have already adopted electronic applications.
The application is generally straight-forward. You'll need to put in your personal information and sometimes the year you took the exam. It takes about 10 to 14 days to process the application.
Call the State Department of Education in the document's originating state if you cannot find any information about requesting GED certificate duplicates online.
