I got a call from 314 and I’m trying to identify the location.

Area code 314 is for St. Louis, Missouri. From what I’ve seen, a quick search online will usually confirm the main city or region tied to an area code. Sometimes, knowing the specific exchange (the first three digits after the area code) can narrow it down further, but that info isn’t always easy to find.
