Is the domestic rate different for state-to-state and in-state calls?
No, the domestic rate within the United States is the same for state-to-state and for in-state calls. It does not change. However additional add-on rates can be added for the calls that are made from Alaska (29¢), Hawaii (4¢), British Virgin Islands (10¢), Guam (7.8¢), Puerto Rico (6¢), and Mariana Islands(22¢). Calls originating from a payphone are subject to FCC mandated payphone fees (69¢).
