Humans and all other vertebrates belong to the phylum Chordata.123

Members of this phylum, known as chordates, are characterized by several features present at some stage of their development, including a stiff, dorsal supporting rod called a notochord, a hollow dorsal nerve cord, and gill slits in the region of the pharynx.12

Within this phylum, vertebrates are classified under the subphylum Vertebrata. They are distinguished from other chordates by the presence of a backbone, which in humans replaces the notochord during embryonic development.23
