There seems to be some confusion about the significance of the phrase “Magnolia 9047,” as it appears in this passage from scene 8 of A Streetcar Named Desire (1947), by Tennessee Williams:
BLANCHE [at the phone]: Hello. Mr. Mitchell, please…. Oh…. I would like to leave a number if I may. Magnolia 9047. And say it’s important to call….
Some well-meaning souls have interpreted Magnolia 9047 as a street address, but it’s very clear that Blanche’s sister Stella and brother-in-law Stanley live in the French Quarter at 632 Elysian Fields Avenue, as this passage in scene 1 with upstairs neighbor Eunice exposits:
EUNICE [finally]: What’s the matter, honey? Are you lost?
BLANCHE [with faintly hysterical humor]: They told me to take a street-car named Desire, and then transfer to one called Cemeteries and ride six blocks and get off at—Elysian Fields!
EUNICE: That’s where you are now.
BLANCHE: At Elysian Fields?
EUNICE: This here is Elysian Fields.
BLANCHE: They mustn’t have—understood—what number I wanted…
EUNICE: What number you lookin’ for?
[Blanche wearily refers to the slip of paper.]
BLANCHE: Six thirty-two.
EUNICE: You don’t have to look no further.
However, Williams’ grasp of light rail routefinding is trumped by the poetics of Blanche traveling from desire to death to her celestial reward, as it is the Canal Street cars that are marked Cemeteries (for the terminus at Metairie Avenue), and this line does not intersect Elysian Fields Avenue.
