GRAYSVILLE prefixes in area code 205

NANPA records 6 assigned NXX blocks to rate center GRAYSVILLE in area code 205, 0.8% of the 785 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. 5 holders hold those blocks, the largest being PAETEC ITEL, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - AL (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2002-01-31 and the most recent 2018-01-09. 5 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 220, 659, 724, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
