I forgot my ACS PIN.
When you access the American Community Survey online, you will be given a four-digit PIN. The PIN is unique to your survey answers. It is needed to re-enter the survey after you logout, or if your session times out. Please remember it.
The Census Bureau cannot remind you of your PIN if you forget it. If you cannot remember your PIN, you may call 1-800-354-7271 to have the survey reset. However, once a survey is reset, you must start again at the beginning.
