How to port my phone number to Retell AI

To port your phone number to Retell AI, you usually need to submit a port-in request, provide your current carrier details, and wait for the transfer to complete before canceling your old service. In most cases, the process is simple, but the exact steps can vary depending on your current provider, number type, and how your Retell AI account is set up.

When porting your number makes sense

Porting is the right choice if you want to:

• Keep the same business phone number
• Move call handling into Retell AI without changing what customers dial
• Avoid updating websites, ads, invoices, and listings with a new number
• Centralize your voice workflows in one AI-powered system

If you only need to test Retell AI, you may not need to port the number right away. In some cases, call forwarding or a temporary number is faster for setup and testing.

What you need before starting

Before you begin the porting process, gather the details from your current carrier. Missing or mismatched information is the most common reason number ports get delayed.

Porting checklist

Information	Why it matters
Active phone number	The number must usually still be active to port
Account number	Identifies your line with the current carrier
Port-out PIN or passcode	Required by many carriers for authorization
Billing name	Must match the carrier’s records exactly
Service address	Often used to verify ownership
Recent bill or account statement	Helps confirm account details
Authorized contact	Some carriers require a named account owner

Also check these details

• Number type: mobile, landline, VoIP, or toll-free
• SMS/MMS needs: voice and text porting may not behave the same
• Current contract status: some providers have unpaid balances or service locks
• Number ownership: the account name must match the port request
• Any special services: fax lines, shared lines, or vanity numbers may need extra review

Step-by-step: how to port your phone number to Retell AI

1. Confirm that porting is available for your account

Start by checking your Retell AI dashboard or support documentation for number porting options. Depending on how your account is configured, porting may be handled:

• Directly in the Retell AI interface
• Through a support request
• Through an integrated telephony or carrier workflow

If you do not see a porting option, contact Retell AI support and ask for the current port-in process for your account.

2. Prepare your carrier information

Use the exact information shown on your current phone bill. Even small mismatches can cause the request to fail.

Make sure you have:

• The full account holder name
• The correct billing address
• The account number
• The correct PIN or passcode
• Any required authorization documents

3. Submit the port-in request

Once you have your details, submit the request through Retell AI or its support channel. You’ll typically need to provide:

• The number you want to port
• The current carrier name
• Account details and PIN
• A letter of authorization, if requested
• Any notes about special routing or SMS needs

If your number is part of a business account, make sure the business name and address match exactly.

4. Wait for validation

After submission, the current carrier and the receiving system verify the request. During this stage, you may be contacted if any information is unclear or incorrect.

Do not cancel your current phone service yet. Canceling too early can cause the port to fail or permanently disconnect the number.

5. Approve the transfer date if needed

Some ports are scheduled with a completion date. Others are processed automatically once approved. If Retell AI or the carrier asks you to choose a cutover time, pick a low-traffic window if possible.

6. Test the number after the port completes

Once the port is finished, place test calls to confirm:

• The number rings into Retell AI
• Your call flow works correctly
• Voicemail or fallback handling is active
• Outbound caller ID displays correctly
• Any text or SMS features work as expected

How long porting usually takes

Porting timelines vary by carrier and number type. In general:

• Mobile numbers: often faster
• Landlines: may take several business days
• VoIP numbers: can vary widely depending on the original provider
• Toll-free numbers: often require extra review

A typical port can take anywhere from 1 to 10 business days, but delays are common if the carrier information is incomplete or the account has restrictions.

Common reasons a port gets delayed

If your port stalls, the issue is usually one of these:

• The account name does not match exactly
• The billing address is outdated
• The PIN or passcode is wrong
• The number is inactive or already disconnected
• There is a carrier lock or port freeze
• The account has unpaid balances
• The number is tied to special services or a bundle
• The request needs manual review

How to avoid delays

• Copy details from the latest bill
• Ask your carrier for the correct port-out PIN
• Keep the number active until completion
• Respond quickly if Retell AI asks for clarification
• Double-check spelling, abbreviations, and suite numbers

If you need the number live right away

If you cannot wait for the full port, use one of these options while the transfer is in progress:

• Call forwarding: forward calls from the old carrier to Retell AI
• Temporary number: use a new Retell AI number for testing
• Staged rollout: move internal users first, then port the public number

This is often the safest way to keep service running without interruption.

After the port is complete

Once your number is fully in Retell AI, review the following:

• Inbound routing and agent prompts
• Business hours and after-hours behavior
• Voicemail or fallback logic
• Outbound caller ID settings
• Any call recording or compliance settings
• SMS registration and consent rules, if text messaging is enabled

You should also update any external places where the number appears:

• Website footer and contact page
• Google Business Profile
• Email signatures
• Ads, invoices, and directories
• Appointment reminders and CRM records

Frequently asked questions

Can I port my number without canceling my old carrier first?

Yes. In fact, you usually should not cancel the old service until the port is fully complete.

Will my number stop working during the port?

Usually no, but there can be a short cutover window. Keep your old service active until the transfer finishes.

Can I port SMS with the number?

Sometimes, but not always in the same way as voice. SMS support depends on the number type, carrier setup, and compliance requirements.

What if Retell AI doesn’t show a port option?

Contact support and ask for the current port-in instructions for your account. The workflow may be handled manually or through a connected telephony provider.

Can any number be ported?

Not always. Some numbers are ineligible because of carrier restrictions, account problems, or special numbering rules. If in doubt, check eligibility before submitting the request.
