HYANNIS prefixes in area code 508
NANPA records 18 assigned NXX blocks to rate center HYANNIS in area code 508, 2.4% of the 749 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. 9 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (6), NEW CINGULAR WIRELESS PCS, LLC - DC (3), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2023-08-02 and the most recent 2026-08-20. 9 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 308, 774 – overlay codes cover the same geography, so a rate center is served by all of them.
