EASTORANGE prefixes in area code 407

NANPA records 9 assigned NXX blocks to rate center EASTORANGE in area code 407, 1.1% of the 786 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. 7 holders hold those blocks, the largest being MCI WORLDCOM COMMUNICATIONS, INC. - FL (2), ONVOY, LLC - FL (2), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2006-01-19 and the most recent 2019-03-27. 8 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 321, 689 – overlay codes cover the same geography, so a rate center is served by all of them.
