HOLYOKE prefixes in area code 413

NANPA records 36 assigned NXX blocks to rate center HOLYOKE in area code 413, 6.0% of the 605 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. 11 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (11), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (8), PAETEC ITEL, LLC (5). The earliest assignment on record here is 2001-05-21 and the most recent 2026-06-25. 26 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 970 – overlay codes cover the same geography, so a rate center is served by all of them.
