HAMPSHIRE prefixes in area code 224

NANPA records 4 assigned NXX blocks to rate center HAMPSHIRE in area code 224, 0.7% of the 595 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 ONVOY, LLC (2), AT&T ENTERPRISES, LLC (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2004-11-01 and the most recent 2024-02-02. 4 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 847, 931 – overlay codes cover the same geography, so a rate center is served by all of them.
