CHPNLTLMTS prefixes in area code 803

NANPA records 8 assigned NXX blocks to rate center CHPNLTLMTS in area code 803, 1.0% 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 (3), TELNYX LLC (2), ONVOY, LLC - SC (2). The earliest assignment on record here is 2008-07-31 and the most recent 2021-04-02. 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 code 839 – overlay codes cover the same geography, so a rate center is served by all of them.
