ELMER prefixes in area code 856

NANPA records 7 assigned NXX blocks to rate center ELMER in area code 856, 1.0% of the 676 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. 7 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (1), TELEPORT COMMUNICATIONS AMERICA, LLC - NJ (1), BANDWIDTH.COM CLEC, LLC - NJ (1). The earliest assignment on record here is 2001-10-04 and the most recent 2024-01-10. 6 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 580, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
