Business density and team size in Iowa
Iowa has 25.7 business establishments per 1,000 residents, 4.6% above the U.S. figure of 24.6. Establishments average 17.0 employees against 16.7 nationally, and payroll per employee is $56,344 (17.6% below the U.S. $68,342). 52.9% of establishments with employees have fewer than five people (U.S.: 55.5%), while 5.4% 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.
| Employment size | Establishments | Share | U.S. share |
|---|---|---|---|
| 1–4 employees | 44,078 | 52.9% | 55.5% |
| 5–9 employees | 15,590 | 18.7% | 17.5% |
| 10–19 employees | 11,344 | 13.6% | 12.5% |
| 20–49 employees | 7,792 | 9.4% | 9.1% |
| 50 or more employees | 4,517 | 5.4% | 5.4% |
Employment-size classes count establishments by mid-March 2023 employment. Establishments with no March employees are excluded from the size classes, so shares are of establishments with employees. Source: Census County Business Patterns 2023.

Choosing an area code in Iowa
2 of Iowa's 5 area codes require ten-digit dialing for local calls; in the others NANPA still lists seven-digit local dialing. None of Iowa's area codes is in an overlay, so each code maps to its own territory. 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.

Callata in Iowa
Callata Office costs $99 per month for up to 5 people, and each additional user is $20 a month. That covers up to 3 local numbers, calling from a browser or your cell, transcribed voicemail, recorded calls with AI summaries, after-hours routing and E911 on each number.
If you already have a number in Iowa, 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.
