MORRISTOWN prefixes in area code 423
NANPA records 28 assigned NXX blocks to rate center MORRISTOWN in area code 423, 3.7% of the 764 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. 10 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (8), PAETEC ITEL, LLC (4), NEW CINGULAR WIRELESS PCS, LLC - GA (3). The earliest assignment on record here is 2001-08-29 and the most recent 2022-03-01. 21 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 201, 315, 507, 680 – overlay codes cover the same geography, so a rate center is served by all of them.
