RIDGELY prefixes in area code 731

NANPA records 3 assigned NXX blocks to rate center RIDGELY in area code 731, 0.8% of the 395 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. 3 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (1), ONVOY, LLC - TN (1). The earliest assignment on record here is 2003-03-11 and the most recent 2016-03-22. 2 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 410, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
