DENMARK prefixes in area code 803

NANPA records 6 assigned NXX blocks to rate center DENMARK in area code 803, 0.8% of the 784 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. 4 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), PAETEC ITEL, LLC (2), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2002-03-04 and the most recent 2013-06-28. 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 207, 274, 319, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
