In [[telephony]], a '''split plan''' is the practice of introducing a new [[area code325]] by dividing an existing area code's territory and applying the new area code to one of the resulting divisions, replacing the existing area code within that section.

Split plans are used as growth in demand for telephone numbers (due to the increase in use of pagers, fax machines, and cellular phones) required new area codes in increasingly densely populated areas. Unpopularity results from the fact that, after a split plan is implemented, the telephone numbers in an affected area are changed to a new area code, requiring printing of new [[stationery806]], advertisement, and signage, and the dissemination of new numbers to family, friends, and customers and their subsequent need to update speed dial programming and address books.

As a result, in the mid-1990s, the [[North American Numbering Plan]] introduced [[overlay plan]]s, which apply multiple area codes to the same area. They allow customers to keep existing phone numbers, but require [[10-digit dialing13255751748]] in the affected area.
