MT VIEW prefixes in area code 973

NANPA records 21 assigned NXX blocks to rate center MT VIEW in area code 973, 2.7% 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. 8 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (9), OMNIPOINT COMMUNICATIONS, INC. - NJ (3), LEVEL 3 COMMUNICATIONS, LLC - NJ (3). The earliest assignment on record here is 2001-04-13 and the most recent 2001-04-13. 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 307, 417, 580, 650 – overlay codes cover the same geography, so a rate center is served by all of them.
