SUDLERSVL prefixes in area code 667
NANPA records 3 assigned NXX blocks to rate center SUDLERSVL in area code 667, 0.7% of the 454 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 U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1), ONVOY, LLC - MD (1), CORE COMMUNICATIONS, INC.- MD (1). The earliest assignment on record here is 2018-10-16 and the most recent 2026-07-27. 3 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 410 – overlay codes cover the same geography, so a rate center is served by all of them.
