Per the VADCFLL registration page (http://va-dcfll.org/teams/start-register-a-team/
), Part 3:
You will not be eligible to register with Virginia + Washington, D.C. until you receive your official FIRST LEGO League team number. This may take up to a week after registering with them (Part 2).
Once you receive your official FIRST LEGO League team number, it may take us up to another week to load it into our system. If a week has passed and you continue to get an incorrect team number error message when you enter your team number, please contact us at [log in to unmask].
Yes, it did take at least a full week for each of my teams to transfer over.
Also, if your team number is less than five digits, add leading zeros to make it five digits. For example, my team's number number 6960 had to be registered as 06960.
