Two ways to get your Grasshopper number to your agent. Forwarding keeps Grasshopper as your phone company and sends calls over. Moving the number (porting) makes Answering Agent your phone company for that number.

​
Forward calls

1

Log in to your Grasshopper account

Via the Grasshopper web app or mobile app.
2

Open Call Forwarding Settings

Go to Settings > Call Forwarding Settings > Extensions; you’ll see a list of numbers and extensions on the account.
3

Edit the number or extension

Click the “edit” button next to the number/extension to configure.
4

Enter the forwarding number

Enter the mobile or landline number (or voicemail) to forward to.
5

Set schedule and behavior

Choose whether calls are announced before pickup, and the time frame the rule applies (24/7, weekends, or custom).
6

Save and test

Save the settings and place a test call to confirm it reaches the destination.
7

Call your business number from another phone

Answering Agent listens for the call. When your agent picks up, the phone numbers step in your dashboard turns green.
Grasshopper does not publish a dial code for forwarding. Use the steps above.

​
Good to know

  • Grasshopper supports forwarding to up to 15 numbers with configurable ring order, ring duration, and forwarding hours.
  • Immediate forwarding sends every call straight to another number with no delay; conditional forwarding only forwards when the line is unanswered, busy, or unreachable.

​
Move your number

Start the move from Dashboard, then Phone numbers, then Add a number, and choose Move my number. Upload your latest bill and we read the details for you. Have these ready:
Do not cancel your service with Grasshopper until the move is complete. A cancelled number can be lost.

​
Watch out for

  • Only paid Grasshopper accounts with no outstanding balance can port out numbers; free-trial accounts are not eligible.
  • Grasshopper does not start, control, approve, or expedite the port-out — the new service provider manages the entire process and timing.
  • Porting out does not cancel the Grasshopper account or its other numbers; removing the ported number or closing the account requires a separate request to Grasshopper Support afterward.
  • Starting a port-out automatically removes any completed SMS Registration on that number; it must be redone with the new provider, and canceling the port does not restore it without restarting registration.
  • Grasshopper cannot cancel or recover a completed port-out; only the new provider can cancel a pending request, and getting the number back requires a fresh port-IN request.
