Three Twenty One is a practical title for this location, since the number is visible on the curtain over the entrance and the building is used in Seinfeld as the exterior of George Costanza’s apartment building. The address associated with George’s apartment in the series is 321 West 90th Street in Manhattan, and this is the home he lives in before he is forced to move back in with his parents.

Three Twenty One appears in Seinfeld (1989–1998). It is used as the exterior of George’s apartment building during the earlier part of the series, before the character loses his job and returns to live with Frank and Estelle Costanza.

In Seinfeld (1989–1998), the building is seen in exterior shots representing George’s apartment building, with the “Three Twenty One” curtain over the doorway making the location identifiable on screen. It functions in the same way that The Shelley serves as Jerry’s building: as a recurring exterior marker rather than a location tied to a single major scene.
