Is usps usually good at telling and fixing when an address is mismarked and correcting it?

Let me start off by saying that I appreciate all your work during this time. I hope this question is considered within guidelines. For some reason irs has continued to mess up my address even after fixing it multiple times my address contains a 3 which for some reason has turned into an 8 for them. I still get mail though as I can see the correct address usually circled in pen and thankfully put in my mailbox. I haven’t had an issue before but with me waiting for the stimulus check to come in, I’m even more nervous/stressed. I feel like this is a really open question but are mailmen/women usually good at telling if the address is wrong and fixing it? They seem to have always caught it every time for me which I appreciate and am beyond thankful but I’m still nervous.

Also, the address with the 8 isn’t even a house so I hope that’s also a giveaway too.
