Is Google Voice or Numberline better for a small business?

Google Voice fits one person who wants a second number, or a team already on Google Workspace that pays per user. Numberline fits a business where several people answer calls and texts, with unlimited users, a greeting and extensions, and a shared inbox for texts and WhatsApp.

Switching from Google Voice takes three steps.

1

Keep your number

Port the number your customers already know, or pick a new local or toll-free one. See the porting guide.

2

Prepare the transfer

Have your Google Voice account details and the number’s transfer PIN ready. Keep Google Voice active until the port completes.

3

Set up your team

Forward calls to each person’s mobile, record a greeting with extensions, and invite the team to the shared inbox.

Questions about switching from Google Voice

Is Google Voice bad?
Google Voice is a solid second number for one person. Its team plans are priced per user through Google Workspace, with ring groups and an auto attendant on higher plans. Numberline adds a shared team inbox, Slack notifications, and WhatsApp, with no per-user fees.
Can I move my number from Google Voice?
Yes, if the number is eligible to port. Porting is free and we handle it. Keep Google Voice active until the move completes, since cancelling early can release the number. See the porting guide.
Do you charge per user?
No. Users are unlimited, so adding teammates, assistants, and contractors never adds a seat fee. See the pricing page.
Do I need a Google account or Google Workspace?
No. Numberline is a virtual phone system for small businesses. Sign in with a work email, invite your team, and keep using whatever email and calendar tools you already have.
Do I need new phones or equipment?
No. Numberline forwards calls to the mobile phones your team already carries, or to an existing business landline. There is nothing to buy. Install the Numberline app to call and text as the business.
