MILTON prefixes in area code 302

NANPA records 6 assigned NXX blocks to rate center MILTON in area code 302, 0.9% of the 656 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. 4 holders hold those blocks, the largest being PAETEC ITEL, LLC (2), ONVOY, LLC - DE (2), TELEPORT COMMUNICATIONS AMERICA, LLC - PA (1). The earliest assignment on record here is 2019-10-10 and the most recent 2024-02-05. 6 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 209, 217, 272, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
