EXETER prefixes in area code 603
NANPA records 15 assigned NXX blocks to rate center EXETER in area code 603, 2.0% of the 752 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 9 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (5), BELL ATLANTIC MOBILE, INC (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NH (1). The earliest assignment on record here is 2002-05-20 and the most recent 2018-10-04. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 207, 402, 417, 559 – overlay codes cover the same geography, so a rate center is served by all of them.
