CUMBLND HL prefixes in area code 401
NANPA records 19 assigned NXX blocks to rate center CUMBLND HL in area code 401, 3.3% of the 581 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 OMNIPOINT MIAMI E LICENSE, LLC (14), PAETEC ITEL, LLC (2), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2001-04-11 and the most recent 2025-08-19. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
