Oklahoma business phone guide

Oklahoma's business economy

Oklahoma had 4.1 million residents in the Census Bureau's July 2024 estimate, up 3.4% from April 2020. The U.S. population grew 2.6% over the same period. County Business Patterns counted 96,402 business establishments in the state in 2023 with 1,431,690 mid-March employees and $78.6 billion in annual payroll. The average establishment has 14.9 employees. 54.0% of establishments with employees had fewer than five people. The three largest sectors by establishments are retail trade (13,097), health care and social assistance (11,795), and professional, scientific, and technical services (10,200).

Oklahoma compared with the U.S.

Oklahoma has 23.5 business establishments per 1,000 residents, 4.3% below the U.S. figure of 24.6. Establishments average 14.9 employees against 16.7 nationally, and payroll per employee is $54,886 (19.7% below the U.S. $68,342). 54.0% of establishments with employees have fewer than five people (U.S.: 55.5%), while 5.0% have 50 or more. Because a handful of large employers lift the average, the share of very small establishments says more about who buys a small-business phone system.

22 Census metro or micropolitan areas include part of Oklahoma. The largest is Oklahoma City, OK with 1.5 million residents.

Which Oklahoma area code to pick

4 of Oklahoma's 5 area codes require ten-digit dialing for local calls; in the others NANPA still lists seven-digit local dialing. In overlays (405/572 and 539/918), the codes share one territory, so a new number may come from any code in the overlay. A business that serves one city usually takes a number in that city's dominant code; one that covers a region can hold up to 3 local numbers on Callata's plan.

Largest Oklahoma cities for local numbers

174 Oklahoma cities and towns have their own local-number page. The most populous are Oklahoma City (405/572), Tulsa (539/918), Norman (405/572), and Broken Arrow (539/918).

What phone service costs a Oklahoma business

Per-seat phone plans multiply by headcount. For the rounded average establishment size in Oklahoma, 15 users on RingCentral RingEX Core come to $450.00 a month and on Ooma Office Pro $374.25, at month-to-month list prices checked September 28, 2026. On Callata the same 15 people cost $299.00 a month, less than either per-seat plan.

Callata in Oklahoma

For $99 a month, Callata puts a team of up to 5 on one plan ($20 for each person after that): up to 3 local numbers, unlimited inbound calls, a pooled allowance of 1,500 outbound US and Canada minutes per user, browser and cell calling, voicemail transcription with urgency triage, recorded calls with AI summaries and business-hours routing, with E911 on every number.

If you already have a number in Oklahoma, porting it to Callata is free. Texting from a local number requires a one-time carrier registration (10DLC, $49), and the numbers available in any area code depend on carrier inventory when you choose them.

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.
