If someone blocks you on the IPhone, will your messages still say delivered

IF someone has an iPhone 7 and they block someone on an iPhone 6 will it still say delivered?!

I'm trying to see if this person blocked me again. But last time they blocked me it didn't say delivered… They are ignoring me now but my messages are saying delivered

I also called and it was a normal Ring… When they blocked me it was just two rings I think

No, if it says delivered they are not blocking you. If it doesn't say delivered, they are. But don't keep calling them and texting them, they might find it annoying.
