CALDWELL prefixes in area code 973

NANPA records 42 assigned NXX blocks to rate center CALDWELL in area code 973, 5.4% of the 779 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. 11 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (13), OMNIPOINT COMMUNICATIONS, INC. - NJ (10), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (8). The earliest assignment on record here is 2001-01-05 and the most recent 2025-07-10. 22 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, 208, 620, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
