Virtual phone extensions for your small business.

Appear bigger and more established with virtual phone extensions from Grasshopper.


What are phone extensions?

Included in each Grasshopper plan, virtual phone extensions allow you to automatically route callers to the information, department, or employee that they need.

With informational extensions, you can share information when customers call (“press 1 for our business hours and location”). Or simply direct customers to the right department or person (“press 2 for sales, 3 for support”).

Virtual phone extensions are cloud-based, so incoming calls to your business number can be re-routed to any mobile device, or automated message, you choose.

Frequently Asked Questions

How do I add an extension to a phone number?

Simple! If you have an existing number, we can port it to Grasshopper for you so you can add an extension. If you decide to get a new number from Grasshopper, it’s even easier. Just sign in and add extensions to the phone number from the Extensions page.

How many extensions can I have with Grasshopper?

Depends on the Grasshopper plan you purchase. Currently, Solo comes with three extensions, Partner with six, and Small Business with as many as you want! See our plans & pricing.

Can I use Grasshopper for existing phone numbers with extensions in my office?

Yes! Grasshopper can forward calls to many existing PBX phone systems using a feature called PBX Connect, which allows you to enter pauses and extension numbers instead of a simple telephone number. 

Does Grasshopper offer toll-free extensions?

Absolutely. All of our toll-free or vanity phone numbers have them by default. These toll-free extensions for phones acts like regular toll-free numbers do. Customers call free while you pick up the tab.
