If you'd like to use your existing Sideline phone number with OpenPhone, we'll be happy to port it for you.

When you are ready to port out your Sideline number, open the Sideline app, go to Settings and scroll to find the Number Porting section.

You can port out your Sideline number if:

  • You originally ported the number into Sideline from another provider
  • You are subscribed to Sideline, have an active subscription that you were grandfathered in, or have paid the one-time fee of $19.99 to unlock the number

Sideline goes over these in their article here - Porting your number out of Sideline

Once you unlock your Sideline number, you will be provided with your:

  • PIN
  • Account number
  1. Please share these with us (send us the screenshot) alongside with your Sideline number and we'll take care of the rest for you. 💪
  2. Once we receive your screenshot, we'll send you a quick form to fill out and sign. It'll authorize us to port your number to OpenPhone. We'll email you this form so you can sign it digitally - no need to print and scan.
