Question: Which U.S. city residents were the first to have phone numbers?
Answer: Residents of Detroit, Michigan, were the first in the nation to be assigned phone numbers. By 1879, the city had grown so large that operators could no longer route calls based on names alone. Just three years earlier, on March 10, 1876, Alexander Graham Bell made the first phone call from New York City to his assistant, Mr. Watson, in Chicago.
