GM return question again

Haven't been a nag in a while as I am slowly getting this, but two questions
1) I sent back for a light duty core return using my proper stickers. The answerback has an application number of DS-4162017H but my green stickers have DS-60 then only 6 blank spots. Did I screw this up? WIll it matter if I try to cram in all the digits?
2) On my PC302 for a core return to Hollingsworth Core Logistics, I looked them up, Dearborn MI to fill out on my 302? It doesn't give me a city and state
THANK YOU!!!
