QUOTE:
My liscence address and mailing address are different... (mainly b/c I've been lazy and haven't had my lisence updated yet. I'll be correct by the time I get to YaoiCon, though).
Can I send a scan of my current (address incorrect) lisence, but show my corrected lisence at the door?
The address on your license and your mailing address don't need to match up. What's important is that it's a photo ID with your name & birth date on it. So it's okay to send a copy of the old license to get you registered.
