Phone number format in area code 775

All phone numbers within area code 775 follow the standard North American 10-digit format:(775) NXX-XXXX. The NXX is the central office prefix (also called an "exchange") and XXXX is the subscriber line number. For long-distance calls within the NANP, dial 1 + 775 + NXX + XXXX. From outside North America, dial your country's international access code, then 1 (the NANP country code), then the 10-digit number.

History of area code 775

Split from 702. Northern Nevada.

The original 86 area codes were assigned by AT&T and Bell Labs in 1947 as part of the North American Numbering Plan. At the time, rotary-dial phones meant codes with lower digits (like 212 for NYC, 213 for LA, 312 for Chicago) were given to the largest cities because they took less time to dial. Today's area code assignments still reflect those early choices, even though touch-tone and cell phones made the original reason obsolete.

Is the 775 area code safe to answer?

Area code 775 itself is a normal geographic code with no elevated spam risk. That said, scammers can spoof any area code — including 775 — so if you don't recognize the full number, let it go to voicemail and verify the caller's identity before calling back.
