ROMULUS prefixes in area code 734
NANPA records 24 assigned NXX blocks to rate center ROMULUS in area code 734, 3.4% of the 701 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 MICHIGAN BELL TEL CO (8), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (4), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-07-19 and the most recent 2020-08-20. 19 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
