775 area code — Reno, NV geographic

Data: NANPA public reports, current as of July 28, 2026.

Area code 775 is a geographic code serving Reno, Nevada in the Pacific and Mountain time zone. It has been in service since December 12, 1998. 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 599 active NXX prefixes in 775, assigned to 51 carriers. 351 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 80 rate centers (billing localities).

Its parent code is 702, which it left in 1998.

Official projections put exhaust at 4Q 2048.

Unusually, 775 spans two time zones (Pacific and Mountain). When returning a call, check which part of Nevada the prefix belongs to — the difference is a full hour.

The dialing plan is 10D for home-NPA local calls and 10D across codes.

Worth noting: 775 is one of the few NANP area codes whose territory spans two time zones.

Practical takeaway: the 775 label narrows geography to Nevada, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

Where is a 775 number from?

775 is assigned to Reno and surrounding areas of Nevada in the Pacific and Mountain time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
