Porting transfers your existing phone number directly into Beside. Once complete, Beside becomes your provider for that number - all calls and texts will be handled inside the Beside mobile app.

📌 Start your port from the Beside mobile app. Porting is currently initiated from the mobile app - support for starting a port from the web app at app.beside.com is coming soon.
Before you start - eligibility
Not all numbers are a good fit for porting to Beside. Make sure you understand the implications before initiating a request.
⚠️ Port with caution - these number types have important limitations:
Carrier numbers tied to a mobile data plan (Verizon, AT&T, T-Mobile, etc.) - you can port these, but it will cancel your data plan, since Beside doesn't provide mobile data. Only do this if you're comfortable losing that carrier plan entirely.
Numbers used for SMS-based verification codes (2FA/OTP) - verification codes are blocked on Beside numbers by default. You can turn Verification Codes on for the line to let them through, but delivery still isn't guaranteed: some services block codes sent to non-carrier numbers. If this number is your main 2FA/OTP number, set up a backup method before porting. 📖 Receive authentication codes
Toll-free numbers - after porting to Beside, outbound texts will not work.
✅ Best candidates for porting:
VoIP numbers from providers like Google Voice, Sideline, Grasshopper, GoDaddy Conversations, OpenPhone, and similar — see 📖 Port your number from a VoIP provider for provider-specific instructions, fees, and gotchas.
Numbers from other business phone providers
How to port your number
Step 1 - Start the porting request in the mobile app
In the Beside mobile app, go to: Settings → Phone Numbers: select the line to which you want to port your number → Configure Number → Port & Replace
Follow the on-screen steps to submit your porting request. You'll be asked to provide some information about your current provider.
💡 If this number is your only way to sign in to Beside:
You'll be asked to add an email address before your request can be submitted. Once the number is ported, sign-in codes sent by text can no longer reach you outside of Beside, so your account needs a second way in.
On iPhone, the flow stops at Add an email to keep signing in, sends a code to that address, and submits your port request as soon as you've entered it.
You can also add an email ahead of time so the port goes through in one pass. 📖 Change your login method
Step 2 - Gather your account details from your current provider
To complete the port, you'll need the following from your current provider:
Your account number - required for every provider, whichever one you pick in the flow
Your account PIN or password
The name and address on the account
💡 About the account number:
It's now asked for in the porting flow no matter which carrier you select, so have it ready before you start.
It isn't always the same as the phone number you're porting. Check your latest bill or your provider's account page for the exact value.
Some providers only release it on request - for a few, it takes a support ticket or an email. 📖 Port your number from a VoIP provider
📌 Note: Keep your current account active until the port is complete. Cancelling your plan early can cause the port to fail.
Step 3 - Our team reviews and submits your request
Once you submit your request, our support team will review the information you provided, follow up with you if anything needs clarification, and confirm once your porting request has been submitted to our carrier.
📌 What to expect:
Our team will reach out via the in-app chat if additional information is needed.
You'll receive a confirmation once the request has been submitted to the carrier on your behalf.
Step 4 - Wait for the port to complete
Porting typically takes under 1 week, but can take up to 2 weeks depending on your current provider.
You'll receive a notification in Beside once your number has been successfully ported.
Step 5 - Complete the setup after porting
Once you're notified that your port is complete, follow the steps in:
Common issues to avoid
Most port requests that fail or get delayed share the same handful of root causes. Check this list before submitting:
Mismatched account information. Name, billing address, and account number must match exactly what is on file with your current provider. Even small differences (missing apartment number, abbreviated street name, business name vs. personal name) can cause rejection. Check your latest bill for the exact format.
Outstanding balance on your current account. Most providers refuse to release a number with an unpaid balance. Clear any charges before submitting.
Expired or wrong PIN. Some providers (Grasshopper, for example) generate port-out PINs that expire after a few days. Generate the PIN close to when you actually plan to submit the port. If your port is rejected for a wrong PIN, generate a fresh one and resubmit.
Account in poor standing. Inactive, suspended, or locked accounts cannot release a number. Resolve any holds (fraud lock, security review, etc.) with your current provider before starting the port.
Number not unlocked (Google Voice). Google Voice requires you to unlock your number before porting. See 📖 Port your Google Voice number to Beside for instructions.
⚠️ Do not cancel your current plan before the port completes:
Cancelling early can cause the port to fail and the number to be released back to the public pool, where it cannot be recovered.
Wait for confirmation from Beside that the port is done before cancelling.

Why does Beside ask for an account number even though my provider didn't need one?
Why does Beside ask for an account number even though my provider didn't need one?
The account number is now required for every porting request, whichever carrier you select in the flow. Our carrier needs it to submit the request, so collecting it upfront saves a round trip with support later. It isn't always the same as the number on your Letter of Authorization - check your latest bill or your provider's account page.
Why is Beside asking me to add an email before I can submit my port?
Why is Beside asking me to add an email before I can submit my port?
Because the number you're porting is currently your only way to sign in. After the port, sign-in codes sent by text can't reach you outside of Beside, so your account needs a second sign-in method first. Add your address in the Add an email to keep signing in step, enter the code sent to it, and your port request is submitted right after. 📖 Change your login method
Can I still receive verification codes on my number after porting?
Can I still receive verification codes on my number after porting?
Only if you turn on Verification Codes for that line, and even then delivery isn't guaranteed - some services block codes sent to non-carrier numbers. If this number is your main 2FA/OTP number, move your 2FA/OTP to an authenticator app or another number before porting. 📖 Receive authentication codes

Yes, but it will cancel your mobile data plan. Since Beside doesn't provide mobile data, porting a carrier number means your data service with that carrier will be terminated.
