YPSILANTI prefixes in area code 734
NANPA records 52 assigned NXX blocks to rate center YPSILANTI in area code 734, 7.4% 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. 16 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (16), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (3). The earliest assignment on record here is 2004-12-27 and the most recent 2023-06-26. 37 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 code 701 – overlay codes cover the same geography, so a rate center is served by all of them.
