During World War II, mail to Los Alamos residents was simply addressed to P.O. Box 1663, Santa Fe, New Mexico. When the Manhattan Project's existence was made known to the outside world in 1945, the “Secret City” could again use its Los Alamos postmark. The Post Office opened in its present location in November, 1948, on the site of the Ranch School Trading Post.
