DUBLIN prefixes in area code 267

NANPA records 5 assigned NXX blocks to rate center DUBLIN in area code 267, 0.6% 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - PA (2), PAETEC ITEL, LLC (2), CALLFIRE, INC. (1). The earliest assignment on record here is 2014-05-16 and the most recent 2014-05-16. 5 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 215, 231, 254, 380 – overlay codes cover the same geography, so a rate center is served by all of them.
