GRAND BAY prefixes in area code 251
NANPA records 5 assigned NXX blocks to rate center GRAND BAY in area code 251, 0.9% of the 528 blocks assigned in the code.

(1). The earliest assignment on record here is 2008-11-18 and the most recent 2023-03-24. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
