Ten-digit and seven-digit dialing in 314

According to NANPA's dialing-plan data, local calls within 314 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Ten-digit local dialing means the area code is part of how customers save and recognize your number, so print it in full everywhere. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion."

Carriers with 314 numbers

33 carriers hold the 783 central office codes assigned in 314. Southwestern Bell has the most, with 252 (32%). 493 of the codes (63%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.

Optional AI agents (receptionist, sales, support or scheduler) can answer calls after hours or when nobody picks up, take messages, text, email and transfer to your team. They are billed from prepaid AI minutes at $0.25 per minute, identify themselves as AI, and may only place outbound calls to people who consented, between 8am and 9pm.
