TYLERTOWN prefixes in area code 601

NANPA records 8 assigned NXX blocks to rate center TYLERTOWN in area code 601, 1.0% of the 783 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. 6 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), LEVEL 3 COMMUNICATIONS, LLC - MS (2), BANDWIDTH.COM CLEC, LLC - MS (1). The earliest assignment on record here is 2002-03-14 and the most recent 2005-02-08. 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 code 769 – 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.
