Most likely, yes. The best rule of thumb is to try by entering the Event Code here. If the system allows you to enter with that Event Code you are still able to place an order.
Keep in mind when ordering after Picture Day shipping options may change and shipping charges may apply. Free shipping to school will end approximately 48 hours after Picture Day.
Some codes, mostly Spring Individual Pictures, may shut off the night before Picture Day. If this is the case, messaging will display when entering the code that says:
"Online ordering for the code entered has ended. If it is the morning of Picture Day, please contact your school to let them know you want your child photographed, or if you received one, send the picture envelope to school with your child."
