ENGLESIDE prefixes in area code 571

NANPA records 27 assigned NXX blocks to rate center ENGLESIDE in area code 571, 4.2% of the 639 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 TELEPORT COMMUNICATIONS AMERICA, LLC - DC (10), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (6), ONVOY, LLC - VA (3). The earliest assignment on record here is 2001-08-28 and the most recent 2025-02-28. 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 703 – overlay codes cover the same geography, so a rate center is served by all of them.
