LEOMINSTER prefixes in area code 978

NANPA records 21 assigned NXX blocks to rate center LEOMINSTER in area code 978, 2.7% of the 773 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 VERIZON NEW ENGLAND INC. (5), METROPCS, INC. (4), PAETEC ITEL, LLC (3). The earliest assignment on record here is 2001-03-19 and the most recent 2016-09-06. 16 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 code 351 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
