STFRD-SNDY prefixes in area code 503
NANPA records 28 assigned NXX blocks to rate center STFRD-SNDY in area code 503, 3.6% 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. 7 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (15), LEVEL 3 COMMUNICATIONS, LLC - OR (3), TELEPORT COMMUNICATIONS AMERICA, LLC - OR (3). 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 code 971 – overlay codes cover the same geography, so a rate center is served by all of them.
