LANCASTER prefixes in area code 740

NANPA records 29 assigned NXX blocks to rate center LANCASTER in area code 740, 3.7% of the 786 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. 13 holders hold those blocks, the largest being OHIO BELL TEL CO (7), AERIAL COMMUNICATIONS, INC. (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (5). The earliest assignment on record here is 2001-02-06 and the most recent 2023-09-28. 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 218, 220, 223, 603 – overlay codes cover the same geography, so a rate center is served by all of them.
