MILAN prefixes in area code 734

NANPA records 7 assigned NXX blocks to rate center MILAN in area code 734, 1.0% 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - MI (2), PAETEC ITEL, LLC (1), MICHIGAN BELL TEL CO (1). The earliest assignment on record here is 2022-03-10 and the most recent 2022-03-10. 7 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 229, 320, 419, 567 – overlay codes cover the same geography, so a rate center is served by all of them.
