Single-state metro and micropolitan areas account for 100% of the statewide total; the rest are outside any published area or in areas Census suppressed.

Team sizes at law offices in Arizona

74.5% of Arizona's law offices with employees had fewer than five people in March 2023, compared with 71.8% nationally. 88.1% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.

Calls a law office in Arizona has to catch

Prospective clients often call a law office at a stressful moment and contact more than one firm, so the first firm to respond has an advantage. Attorneys are frequently in court or meetings, which makes accurate message taking and routing to the right paralegal essential. That holds for law offices in Arizona as much as anywhere.

A few of the calls that come in to law offices in Arizona:

• An existing client calls for an update on their matter.
• Someone calls after a car accident to ask whether the firm handles injury cases.
• Opposing counsel calls to discuss scheduling.

What law offices text about

Firms use texting for appointment reminders and document requests, keeping privileged discussion off text.

Texting from a local number in Arizona requires carrier registration (10DLC), a one-time $49 fee on Callata.

What a phone system costs a law office in Arizona

Law offices in Arizona average 5.6 employees, so the comparison uses a 6-person team. Per-seat business phone plans bill every one of those people. At month-to-month list prices checked September 28, 2026, 6 users on RingCentral RingEX Core cost $180.00 a month and 6 on Ooma Office Pro cost $149.70. Callata comes to $119.00 a month for 6 users ($99 a month with 5 users included, then $20 per additional user), below both.

Over a year, that is $732 less than RingCentral for a law office in Arizona of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.

Area codes in Arizona

Arizona has 5 geographic area codes in service according to NANPA. Callata includes up to 3 local numbers, so a law office can hold a number in more than one of them.

How Callata works for law offices in Arizona

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.

Porting a number you already use in Arizona is free, and business texting is available once the carrier registration (10DLC) is approved; the registration carries a one-time $49 fee. Which specific numbers are open in a given area code depends on carrier inventory at the time you sign up.

AI agents are optional: an AI receptionist or scheduler can pick up when the team is busy or closed, take a message, send a text or email, or transfer the call. They draw on prepaid AI minutes ($0.25/minute), disclose that they are AI, and outbound AI calls require prior consent and are limited to 8am–9pm.

Firms should consider privilege and confidentiality before recording calls or using AI summaries, and follow their bar's guidance on client communications.
