832 area code — Houston, TX geographic
Phone numbers beginning 832 are registered to the Houston area of Texas (Central time zone). The code entered service on January 16, 1999. Together with 281, 346, 713 it forms the 281/346/713/832 overlay. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.
NANPA lists 786 active NXX prefixes in 832, assigned to 31 carriers. 704 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 43 rate centers (billing localities).
Practical takeaway: the 832 label narrows geography to Texas, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.
