DORA prefixes in area code 205

NANPA records 8 assigned NXX blocks to rate center DORA in area code 205, 1.0% 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. 6 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), PAETEC ITEL, LLC (2), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2002-01-31 and the most recent 2022-01-31. 7 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 417, 575, 659 – overlay codes cover the same geography, so a rate center is served by all of them.
