LANSING prefixes in area code 517
NANPA records 164 assigned NXX blocks to rate center LANSING in area code 517, 26.6% of the 616 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. 37 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (59), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (25), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (17). The earliest assignment on record here is 2001-02-28 and the most recent 2026-06-02. 90 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 336, 464, 563, 607 – overlay codes cover the same geography, so a rate center is served by all of them.

Is LANSING a city?
It is a rate center – the unit NANPA allocates number blocks to. Its name is abbreviated to ten characters and is not necessarily a settlement: we print it as recorded rather than guess at the full name.
