Beginning July 1, Arcadia will no longer be a one-ZIP code town.
With the volume of mail in the city increasing rapidly, the U. S. Postal Service has decided to add three ZIP codes, two of them for box patrons, a postal spokeswoman said.
Growth in the city prompted postal officials to add six delivery routes during the last two years, said Kathleen Cather, director of marketing for the Pasadena Postal Processing Center, which handles Arcadia's mail.
Residents living south of the Foothill Freeway and west of Santa Anita Avenue will have the new ZIP code of 91007. Other Arcadia residences will keep the current ZIP code of 91006.
