That’s what developers of a new condominium at 212 Fifth Avenue are hoping. The prestige of Fifth Avenue is world-famous (it also adds a 5- to 10-percent premium to the price of an apartment), and as anyone who was around back in the days of analog phone exchanges knows, 212 is synonymous with Manhattan. Reporting on the “New York-iest address,” the Daily News mentions how even “Seinfeld”‘s Elaine steals her dead neighbor’s 212 phone number after she gets changed to a 646 area code. “The bearer of a 212 phone number looks like a longtime New Yorker. It’s the ultimate luxury accessory,” the paper says.
