PONTIAC prefixes in area code 248
NANPA records 150 assigned NXX blocks to rate center PONTIAC in area code 248, 19.1% of the 784 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. 18 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (40), NEW CINGULAR WIRELESS PCS, LLC - IL (28), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (23). The earliest assignment on record here is 2001-05-24 and the most recent 2023-10-12. 70 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 779, 810, 815, 947 – overlay codes cover the same geography, so a rate center is served by all of them.
