The Best Apps for a Second Business Phone Number
Published:
Updated:

We’ve all been in conversations with a coworker or boss who asks for our number, and we cringe at the idea of giving them our actual phone number. What if they call on holidays and weekends? Using a second phone helps maintain more privacy between colleagues and allows for you to turn it off while keeping your main phone on. In the end, SmartLine took the cake for the best second phone line app, but read on to find out the other best apps we tested in this category.

  • The app has a beautiful design and interface that is easy to use and well organized.
  • You can select a number in your area code and set up a personalized voicemail.

Google Voice is a great pick for people who use Google products regularly.

Why we chose Google Voice:

  • Calls within the US are free so if that is the only place users are calling, they can end up spending nothing using this app.
  • The app syncs up to your Gmail account, keeping everything in one place if you use Gmail.
  • The app does not use wifi or a data connection and runs on your monthly minutes so you don’t have to have internet access to use it
  • Great for small business owners and people who don’t want to give out their personal numbers at work.

This app has great features that make it easy to use and beneficial for small business owners and other professionals.

This app forwards calls to your regular phone, which keeps everything in one place.

Why we chose Line2:

  • $9.99 a month or $99 a year, which is on par with the other services we tried.
  • Settings allow you to choose to show calls in your phone’s recent list so that all the calls are together.
  • Great for people who struggle with keeping track of logs and information in an app.
  • Select a number with your zip code so callers recognize your number when you call.

This is the best pick for those who maybe aren't quite as technologically savvy or just prefer simplicity and keeping everything in one place.

This app is great for those who need multiple numbers.

Why we chose Burner:

  • This app allows users to have up to 3 lines so this is great for those who run multiple businesses or side hustles.
  • Free for 7 days and then $9.99 a month after.
  • Whenever you’re done with a number, just go to the burn button and delete the number.
  • Edit the appearance by selecting a different background color for a personalized experience.

Use the app for multiple businesses and projects, and to block spam callers.

    NOTE: Google Voice only works for personal Google Accounts in the US and Google Workspace accounts in select markets. Text messaging is not supported in all markets.

    Backed up and searchable
    Calls, text messages, and voicemails are stored and backed up to make it easy for you to search your history.

    Manage messages across devices

    Your voicemail, transcribed

    Keep in mind:
    • Google Voice is currently only available in the US. Google Voice for Google Workspace users is available in select countries. Check with your administrator for access.
    • Calls made using Google Voice for Android can be placed through a Google Voice access number. All access number based calls use the standard minutes from your cell phone plan and may incur costs (e.g. when traveling internationally).
