Start by contacting the institution or agency where you completed your GED testing. This could be a community college, university, or adult education center. If you don't remember where you took the test, consult your state's website for a list of testing centers and agencies in your area.
Download or obtain a paper copy of the GED replacement certificate form. In most states, this form is available for download directly from the state website. Complete all sections of the form; you'll need the full name under which you tested, your Social Security number, date of birth, the name of the school or center that administered your test, and the approximate date you took the test. You'll also need to provide a complete mailing address where your replacement may be sent, as well as your signature.
Submit the completed GED replacement form to the agency that administered your test. Some agencies may allow you to submit the form online or through email, or you may mail it in. Check with your agency to see what method they recommend for faster processing.
In most states, you'll need to pay a required processing fee to replace your lost GED. This fee can vary from state to state, and is usually printed somewhere on the GED replacement form. Most states charge anywhere from $10 to $25 dollars to replace a lost GED. If the form is mailed in, you'll need to include a money order or cashier's check in the amount of the fee, made payable to your state treasurer. Some states also allow you to submit payment electronically on their website, using a debit or credit card.
Allow a week or two for the agency to send your duplicate GED. It may take three to seven business days to fully process your replacement request, and another few days for the duplicate copy to come to you in the mail. If time is an issue, most states can expedite the process for an additional fee. This fee can vary from state to state.
