STEUBENVL prefixes in area code 740

NANPA records 19 assigned NXX blocks to rate center STEUBENVL in area code 740, 2.4% 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. 8 holders hold those blocks, the largest being OHIO BELL TEL CO (6), AERIAL COMMUNICATIONS, INC. (3), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2002-03-21 and the most recent 2005-06-01. 13 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 220 – 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.
