BRANDYWINE prefixes in area code 240

NANPA records 8 assigned NXX blocks to rate center BRANDYWINE in area code 240, 1.0% 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. 7 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - MD (2), PEERLESS NETWORK OF MARYLAND, LLC (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2001-02-13 and the most recent 2022-01-10. 8 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 codes 301, 304, 681 – overlay codes cover the same geography, so a rate center is served by all of them.
