SOUTHFIELD prefixes in area code 947
NANPA records 19 assigned NXX blocks to rate center SOUTHFIELD in area code 947, 9.0% of the 211 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. 10 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (3), METROPCS, INC. (2). The earliest assignment on record here is 2006-02-01 and the most recent 2024-09-24. 19 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 248, 810 – overlay codes cover the same geography, so a rate center is served by all of them.
