Answer Wiki. Between 1 to 5 days, depending where it is going. Mail from a major city to a major city can sometimes arrive the next day, even when the cities are across the country, because both are major distribution hubs. Any travel time from a major distribution hub, on either end, will add more time. For example, rural areas can take 4 days for first class mail.
