PTLM SWIFT prefixes in area code 707
NANPA records 12 assigned NXX blocks to rate center PTLM SWIFT in area code 707, 1.5% of the 785 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. 6 holders hold those blocks, the largest being PACIFIC BELL (6), ONVOY, LLC - CA (2), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (1). 10 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 369 – overlay codes cover the same geography, so a rate center is served by all of them.
