NEW iPad passcode issue 😩

i just bought two brand new ipads today. I used the same info for both to link to my apple id and now it has worked for one but when I went to put in the same passcode on the second it has locked me out saying its incorrect. It isnt incorrect! I linked both with my phone and when I looked it showed both iPads on there. I deleted the one not working hoping I could start over but it’s still wanting a passcode. Every time I put it in (the correct one) I get locked out. I can’t do anything on it. I can’t even get to settings due to the passcode issue. Highly frustrated. 😩
