DELRAY BCH prefixes in area code 561
NANPA records 98 assigned NXX blocks to rate center DELRAY BCH in area code 561, 12.5% of the 786 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. 20 holders hold those blocks, the largest being OMNIPOINT MIAMI E LICENSE, LLC (23), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (20), NEW CINGULAR WIRELESS PCS, LLC - GA (17). The earliest assignment on record here is 2001-03-23 and the most recent 2025-04-25. 75 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 728 – overlay codes cover the same geography, so a rate center is served by all of them.
