USPS has only one "correct" address per delivery address, but mail delivery people are logical and can figure out small differences and so can the USPS machines, generally. Also, part of the address may be for internal use by the school, like an ATTN or a department name etc. Example, If I put my apartment # without the letters "apt" before it, it is technically not in the USPS database. But it will get delivered. If I leave the "Ave" off the end of my street name, technically it's invalid, but again, it will be delivered.

My point is, if you are 100% sure you have the correct transcript address (this is usually NOT the same address as the school, so check carefully), there should be no problem. Plus, it's so early that if they don't get it, you have plenty of time to resubmit.
