POWAY prefixes in area code 858
NANPA records 45 assigned NXX blocks to rate center POWAY in area code 858, 8.0% of the 564 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. 17 holders hold those blocks, the largest being T-MOBILE USA, INC. (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (7), PACIFIC BELL (7). The earliest assignment on record here is 2001-05-17 and the most recent 2024-06-17. 31 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 619 – overlay codes cover the same geography, so a rate center is served by all of them.
