How to get a business phone number with ZenPhone

All plansBeginner5 minutesUpdated October 17, 2026

Open the Phone section and choose Get a Phone Plan to build your ZenPhone subscription: pick how many lines you need, then add your phone numbers and assign them to team members. Calls and texts run right inside WorkZen on web and mobile.

Running a business on your personal cell means every client has your number forever, and every dinner gets interrupted. ZenPhone gives your company real business lines that live inside WorkZen: calls, texts, voicemail, and history, all attached to the client records they belong to.

Build your plan

ZenPhone is a separate subscription from your WorkZen platform plan, sized to your team:

  1. Open the Phone section and choose Get a Phone Plan.
  2. Pick your Number of Lines (each line is a phone number).
  3. Need more calling minutes than the lines include? Add them any time afterwards with Add Minutes on Company Settings > Phone Plans, 100 at a time, billed monthly. Texting is already unlimited.
  4. Consider the ZenPhone Max add-on per line to listen to call recordings and get automatic transcription, AI call analysis, and voicemail transcription.
  5. Choose monthly or annual billing (annual and multi-line volume discounts apply) and continue to checkout.

If your account is new, WorkZen may ask you to confirm your phone before the purchase goes through: a Verify your phone window opens, choose Send code by text, type the code we text you, and click Verify. It is a one-time step. A brand-new account may also see Your phone line is being reviewed at the top of the numbers list for a few hours after purchase: incoming calls and texts work right away, and outgoing calls switch on as soon as our team approves the line.

Every line includes unlimited texting, monthly calling minutes, voicemail, caller ID, call forwarding, call waiting, and three-way calling. Current pricing is on the pricing page.

Add and assign numbers

With the plan active, the Phone section shows your line slots:

  1. Click Add Number and claim a number for each slot.
  2. Already have a business number? You can port it to WorkZen instead of claiming a new one.
  3. Assign numbers to team members, so each tech can have their own line, or share lines across the team.
  4. Set one number as the default for outgoing text messages (the numbers list warns you until you do).

Outgoing calls, and any call-flow forward to an outside number, are limited to your company's country (the US and Canada count as one region), and premium-rate numbers are always refused. Need to call another country for your business? Contact support and we can enable it for your account.

Check your minutes

On My Numbers, click Usage to see this period at a glance:

  • Voice minutes: how many are left from the minutes your lines share, the period dates and when minutes reset, and the minutes and texts of each line. If your pace this period would reach the limit before it resets, it tells you.
  • AI Receptionist minutes, if you have the AI Receptionist: its own minutes, separate from your lines.
  • Text messages: no monthly limit, but up to 200 a day for conversations and 200 a day for automatic texts (document links, On my way); past that, that kind of text pauses until the next day. You also see how many were sent and received this period.

Admins get an alert at 80% of the minutes. Once you go over your included minutes, outbound calls can pause until the minutes reset, and incoming calls keep ringing.

Admins also get two buttons at the bottom of Usage: Add minutes opens the Extra minutes window on Phone Plans (100 at a time, billed monthly), and Manage plan opens Phone Plans to change or add a plan. Add minutes shows when your lines have included minutes to top up.

Where calls and texts happen

  • Web: the Phone section has a dialer, call history, voicemails, and your messaging inbox.
  • Mobile: the WorkZen app rings wherever you are, with the same history and messaging.
  • Desk phones: register SIP desk phones and softphones to ring on real hardware. See connecting VOIP desk phones.
  • Routing: decide exactly how inbound calls behave, business hours, menus, ring groups, voicemail, with call flows, and answer around the clock with the AI Receptionist.

A per-line add-on that unlocks the premium capabilities. With it you can listen to your call recordings and read their automatic transcripts and AI call analysis, and voicemails are transcribed. Calls are recorded on every plan (unless you [turn call recording off](/en/help/phone-ai/turn-call-recording-on-or-off/)), and voicemail plays on every plan.

Yes. Calls ring in the WorkZen mobile app wherever you are, and call flows can also forward to an outside number in your company's country (the US and Canada count as one region). Your clients only ever see the business number.
Outgoing calls and call-flow forwards are limited to your company's country, with the US and Canada treated as one region, and premium-rate numbers are always refused. This protects your account from toll fraud. If your business genuinely calls another country, contact support and we can enable it for your account.
No. Emergency numbers are blocked on every WorkZen line, from the app, a desk phone, a call flow or a transfer, and the call will not connect. A WorkZen number has no registered emergency address and cannot give a dispatcher a reliable location, so keep a mobile or landline for emergencies at every location and make sure your team knows.
New accounts may be asked to confirm a phone number by text before checkout completes, and a brand-new account may see its line under review for a few hours after purchase. Incoming calls and texts work right away; outgoing calls switch on once the line is approved.
