Do you remember the times when the only way to separate business from private calls was to carry two phones with you all the time?

If you forgot your business phone at home, no one was able to reach you, resulting in missed calls from potential customers. 

That’s no longer the case, thanks to top business phone number apps that allow you to have multiple virtual numbers on the same device. 

Virtual phone apps are taking over traditional phone systems. The global VoIP market size in 2022 already exceeded $40 billion. The thriving future of this technology is linked to the growing popularity of widely accessible 5G networks and a growing number of SMEs looking for affordable, scalable communication systems.

Now, the question is: which business phone number app to choose?

We’ll try to make it easier for you by comparing top business phone number apps that you can find on the market.

How to choose top business phone number apps

Choosing the best business phone system depends on many factors. It’s always a good idea to compare different plans and make your own list of pros and cons, according to your needs.

Here are some things to consider when making the decision:

  • Price: Prices of different business phone apps vary a lot, depending on the features they have and sometimes on the size of your team as well (the more team members, the cheaper the price per person). It’s important to make a list of features that are non-negotiables for you, and the budget you’re willing to spend.
  • Phone numbers: While some apps are limited to local phone numbers, others allow you to use different area code numbers, as well as vanity and toll-free numbers. Most providers offer free calls in the US, but some of them also have discounts for international calls.
  • Advanced features: Again, advanced features depend on your needs and what’s important to you. For some it’s call recording or transcription, for others it’s being able to collaborate with your team and share dashboards.
