ELSBR-PINL prefixes in area code 341

NANPA records 9 assigned NXX blocks to rate center ELSBR-PINL in area code 341, 8.0% of the 113 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. 4 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), FRACTEL, LLC (3), ONVOY, LLC - CA (1). The earliest assignment on record here is 2020-08-25 and the most recent 2025-11-28. 9 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 510 – overlay codes cover the same geography, so a rate center is served by all of them.
