This link (https://www.ncleg.gov/FindYourLegislators) is maintained by the North Carolina General Assembly (NCGA). The site reminds us that all residents of North Carolina are represented in the United States Senate by both Senators Richard Burr and Thom Tillis. Representation in the NC House, the NC Senate, and the US House is determined by district. Each resident of the state has one representative in each of those legislative bodies, determined by the district in which their residence falls. Detailed district plan information, including maps and reports, can be found via the NCGA redistricting page.
