Display callers name

I have an iPhone 6. By default it only displays the phone number of the caller unless I add a contact name to the number shown after I answer the call. Is there any way to get my phone to show the callers name before I answer it? Is there some of setting I can select to show who is calling me such as businesses, residents, salesmen or whomever? I’m so tired of answering every call that I receive because only a phone number is shown and most of the calls are robo callers. Thank you.
