What happens if I wrote a zip code twice?

I ordered a dual-credit course transcript to be sent to Florida State University, but I accidentally put in this for the city, state, and zip:



Tallahassee, FL 32306-2400, FL 32306-2400



It's been mailed by the institution today. I think it'll send just fine, but what do y'all think? I ordered a second transcript with a correct address, just in case.What happens if I wrote a zip code twice?
As long as it's the same zip your fine.
