Get Started with the Business Phone System That Will Make You Money

After you sign up for Ninja Number, you’ll receive your activation email with your new Ninja Number and login details.

If you signed up on our website, download the app for either Android or iOS. Search for “Ninja Number” in the store if you don’t have access to the links on your phone.

Flex Plan Users:


  1. Open the app and sign in using the username and password we gave you in the email. You’ll be asked to enter your cellphone number. When you enter your number, you’ll link your cellphone to your Ninja Number so all phone calls come to your phone.
  2. After we verify your cellphone number, you can set up your Ninja Number voicemail and begin accepting calls and SMS messages. From the home screen, you can see your leads, voice and text messages, and call history.
    • The Leads tab is any calls or text messages that are “open,” meaning they’ve been missed or not responded to. You’ll easily be able to “close” these, which removes them from this list, so you can quickly track which of your calls or messages still need a reply.
    • The Messages tab shows a history of all of your voicemail or text message exchanges.
    • The All tab stores incoming and outgoing phone calls as well as your SMS exchanges.
  3. To make calls, send texts or add a contact, tap the plus button at the bottom of the screen.
  4. You can access most settings and commands by clicking the three horizontal lines at the top right. We’ve included a ‘Hold Calls‘ toggle so you can quickly send callers to voicemail if you are busy. ‘Hold Calls’ will send callers to your Ninja Number voicemail when its on (red). When ‘Hold Calls‘ is off (green), all incoming calls will call forward to your cellphone. The NinjaBot is our AI-powered chatbot that talks you through how to set up various tools within the app.

If you don’t have your phone, visit our online dashboard to see your calls and make changes to your setup.

Multi Plan Users:

  1. Go to our online dashboard and sign in using the username and password we gave you in the email.
  2. You’ll be taken to the dashboard. You can see in the upper right-hand part of the screen that you’re on the Multi Plan.
  3. In the “Your Extensions” window, click on the “Configure” button. You’ll be able to set your greeting and office hours as well as set up each extension you need for your business.
