CALDWELL prefixes in area code 201

NANPA records 6 assigned NXX blocks to rate center CALDWELL in area code 201, 0.8% 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. 2 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (5), OMNIPOINT COMMUNICATIONS, INC. - NJ (1). 4 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 208, 620, 740, 862 – overlay codes cover the same geography, so a rate center is served by all of them.
