(520) Area Code Business Phone Numbers
The 520 covers Tucson and most of southern Arizona, split off from the old 602 back in 1995. If your customers are in the Old Pueblo or anywhere south of Phoenix, a 520 number tells them you are nearby.

When 520 was carved out of 602 in 1995, it took in Tucson and a huge chunk of southern Arizona, from Nogales up to the Pinal County line. It has stayed a single area code ever since, which is unusual for a region this size and part of why a 520 number still reads as locally rooted rather than reassigned from somewhere else.
Tucson runs on small operators. Nearly 80% of businesses in the metro employ ten workers or fewer, from desert landscapers in Oro Valley to restaurants near the University of Arizona campus [1]. New openings have been picking up too, with recent reports showing about a 3% bump in small business starts and roughly 150 new ventures leaning into hospitality and retail [2].
In a town where word of mouth still moves faster than ad spend, a 520 number on your website or truck signals you are part of the neighborhood. Customers in Sierra Vista or Casa Grande are more likely to answer a familiar area code than an 800 number or a Phoenix prefix, and that first answered call is often where the relationship starts.
Cities Served by the 520 Area Code
The 520 stretches across Pima, Santa Cruz, Cochise and parts of Pinal counties. It covers Tucson and the surrounding desert communities, plus the border region down to Nogales.
Phone Features Built for Tucson Businesses
Every Tonet plan includes the full feature set. The difference between Pay As You Go and Unlimited is only how usage is paid, not what you get.
Auto Attendant
Greet callers with a recorded menu that routes to sales, support, or an outside number. Nest menus as deep as you need, with keys 1 through 9 plus 0, star and pound.
Call Recording
Flip recording on per number for incoming, outgoing, or both. Recordings are kept for 90 days by default and are searchable from the dashboard.
AI Transcription
Recorded calls get speaker-labeled transcripts, and every voicemail is transcribed and emailed to you. Scroll a conversation instead of relistening.
Business SMS
Text customers from your 520 number with SMS and MMS, shared across your team. Sending needs a one-time 10DLC carrier registration filed from the dashboard.
Mobile App
iOS and Android apps use the same login as the dashboard, so a Tucson plumber can take a 520 call from a job site in Marana without missing the next one.
Daily Billing
Plans start at $10 per user per month, billed daily against a prepaid balance. Numbers are $2.50 each per month, with no contract and no seat minimum.
Frequently Asked Questions
Can I get a 520 number if my business is not in Tucson?
Yes. Tonet does not require a local address to buy a 520 number. You pick the area code in the dashboard and the number works right away, whether you are based in Tucson, Phoenix, or outside Arizona entirely.
Can I keep my existing 520 number?
Yes, porting your number to Tonet is free. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. Your number keeps working with your existing provider until the switch finishes, so there is no downtime.
Does the 520 area code have overlays?
No. The 520 has stayed a single area code since 1995, which is rare for a region covering more than a million people. Phoenix split off onto 480 and 623 years ago, but southern Arizona has not needed an overlay yet.
How much does a 520 number cost?
Numbers are $2.50 per month each. Plans start at $10 per user per month on Pay As You Go, plus 1 cent a minute and 3 cents a text. Unlimited is $15 per user per month for US calls and texts under a fair-use policy.
Can I ring the 520 line to a team spread across Tucson and the suburbs?
Yes. Set up a ring group so a call hits every team member at once, in the browser, on the mobile app, or on a desk phone. If nobody picks up, the call goes to the group voicemail with a transcript sent by email.
