CLACKAMAS prefixes in area code 503
NANPA records 49 assigned NXX blocks to rate center CLACKAMAS in area code 503, 6.2% 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. 10 holders hold those blocks, the largest being QWEST CORPORATION (24), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (6), TELEPORT COMMUNICATIONS AMERICA, LLC - OR (5). 27 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.
