First-time user? Your PIN will be your date of birth in the MMDDYY format (Month, Day, Year). That’s 2 digits for the Month, 2 digits for the day and 2 digits for the year. For example, if your birth date is March 25th, 1983 your PIN will be 032583. If this doesn’t work you can try the last 6 digits of your GWID # or the MMYY99 format (038399 for the March 25th, 1983 date example).
