Vertebrates are chordates in which notochord has been transformed into the vertebral column.The ones called protochordates have notochord present that is not transformed into the vertebral column. The term chordata is given to phylum and verterbrata to suphylum of the phylum chordata.

Chordates have a notochord, a dorsal hollow nerve cord, pharyngeal gill slits (even if the animal only has them as an embryo), and a postanal tail.
A vertebrate has all of those plus a spine.

All vertebrates are chordates. Not all chordates are vertebrates; there are also sea squirts and lancets. Vertebrates are the only ones with spinal columns.

A vertebrate doesn't necessarily have to have a spinal cord in there ending in the brain and sending nerves thoughout the body.
Essentially they're the same though.
