Reconfigure telephone numbers in iPhone contacts

My iPhone has suddenly changed American telephone numbers into a French format so 914 205 xxxx becomes 91 420 5xxxx. I cannot get through to anyone unless I edit the numbers by adding +1 at the beginning. Is there any way to convince the iPhone that I live in the United States and therefore 1 is the default country code? It is true that I have a number of foreign telephone contacts too, but the US was always the default until now.

iPhone 6, iOS 11.0.1

When I went to Settings to follow your advice I found that there was a software update to install. Once updated, my phone has gone back to normal telephone configuration so all is well. This was evidently a bug that needed the update, though the update did not specify that it was addressing the issue. For the record, the Language and Region are set to the United States. Thank you anyway for good advice -- I had been looking in Settings>Contacts and finding nothing.
