ST HELENS prefixes in area code 503
NANPA records 6 assigned NXX blocks to rate center ST HELENS in area code 503, 0.8% 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. 5 holders hold those blocks, the largest being QWEST CORPORATION (2), NEW CINGULAR WIRELESS PCS, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OR (1). 4 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 971 – overlay codes cover the same geography, so a rate center is served by all of them.
