Sound Smart And Start Talking Up Right Now The “Rising Political Influence Of 10065”

10021, the 90210 of Manhattan, is set to be split into three new zip codes, confounding demographers*:

The U.S. Postal Service has plans to announce that the affluent neighborhood now identified by the 10021 zip code — stretching between East 61st and East 80th streets, from Central Park to the East River — will be divided into three zip codes in July, leaving 10021 for roughly a third of its original area.

“Too many people” is a reason for the change, Rep. Carolyn Maloney said, adding that was also why the Upper East Side needs the Second Avenue subway. She met with a postal district manager, Robert Daruk, on Friday. Ms. Maloney said, “Pretty soon the other two numbers will be just as honored and prestigious” as 10021.

Not everyone agrees. “This is a puzzle to me,” said the co-chairwoman of Defenders of the Historic Upper East Side, Teri Slater. Ms. Slater said 10021 was widely considered “the zip code” to live in on the Upper East Side. She joked that like Gaul, it was being divided into three parts. She said the post office would have to demonstrate a real need. “I don’t think this is going to sit favorably with many people,” she said.

An Upper East Side resident and president of a co-op on East 79th Street, Theodore Siouris, said people in his neighborhood have expressed concern over no longer being in the 10021 zip code.

. . .

A spokeswoman for the USPS, Pat McGovern, said the growth in the number of addresses and the volume of mail in the neighborhood are prompting the two additional zip codes.

Without describing exactly where the cutoff will be, she said the middle area would remain 10021; the area to the south would be 10065 and to the north would be 10075. She said the mail for all three zip codes would still operate out of the Lenox Hill Station on East 70th Street.
