Switching to Rally Corp doesn’t mean you need to give up your existing phone number. Whether it’s a local number, toll-free, or part of a messaging service, you can bring it with you. This process is called “number porting.”
Below, we walk you through what to expect and what forms you'll need to complete to get started.
What Is Number Porting?
Number porting allows you to transfer your phone number from your current provider to Rally Corp so you can keep using the same number, just on a better platform. This is ideal if you’ve been using a developer-focused or bulk-messaging platform and are ready to upgrade to a results-driven, human-centered mobile messaging solution.
What You Need to Get Started
Before we can begin the porting process, we’ll need:
Letter of Authorization (LOA)
This form gives Rally Corp permission to request the port on your behalf. It must include:The name on your current phone bill (exact match).
The physical service address (no P.O. boxes).
The list of phone numbers to be ported.
Your account number and PIN (if applicable).
Your signature and date.
A Recent Invoice or Statement*
This should include:Your name or business name.
The billing address on file with your current provider.
The numbers you wish to port.
(Optional but Recommended) Customer Service Record (CSR)
This technical record from your current provider can help us confirm all necessary details, including line types and authorized contacts, to reduce the chance of rejections or delays.
Note: Carriers use billing documents to prove that you own the phone number(s) you are attempting to port. Without correct documentation, your port request can be rejected.
If you are porting a Google Voice number…
Please take a screenshot of the Google Voice settings page making sure the phone number and your email address appear in the screenshot.
If you are porting a Toll Free, Landline, or VoIP number…
Please send us your latest monthly bill which includes the phone number(s). If your provider does not provide you with a bill, please provide a receipt of phone number purchase and/or a screenshot of your account portal with the phone numbers included.
Porting Process: Step-by-Step
Here’s how the process typically works:
Step 1: Submit Your Request
Contact us to initiate the process. We’ll confirm number eligibility and send you a custom LOA form (you can also download it here) and request your latest bill.
Please be sure to include a billing statement (see note above)
Step 2: Rally Corp Submits the Port Request
Once we receive all documents, we’ll initiate the port with your current carrier.
Step 3: Wait for Carrier Approval
Porting requests typically take 5 to 15 business days, though some toll-free numbers may process faster. During this time, your number will remain active with your current provider.
Note: The process can take 4 weeks or even longer if the carrier rejects the initial transfer request or if your current vendor does not release it quickly.
Step 4: Cutover & Activation
You’ll receive a notice from our team when the port is scheduled to go live. We’ll test it, validate message delivery, and confirm your number is live in the Rally platform.
🚫 Important: Do not cancel service with your current provider until the port is complete. Doing so may result in losing your number.
What Happens to TCR Registration When You Port a Number?
When you port a number—especially a 10DLC number—from one provider to another (e.g., from Twilio or Infobip to Rally Corp), the campaign registration and vetting details do not transfer automatically.
⚠️ You must re-register that number under the new provider’s ecosystem.
New Registration Required
Even if the brand and campaign have already been approved, the number must be re-associated with that campaign through Rally Corp.
This means we will submit a new secondary vetting request linking your number to your campaign and brand under our A2P pipeline.
Expected Delays
Most 10DLC campaigns are approved within 24–72 hours, but vetting delays (especially for certain verticals like political or financial services) can take 5–10 business days.
During this time, the number cannot be used for A2P texting (though it may still be able to receive inbound).
How Rally Helps Minimize Downtime
At Rally Corp, we help you:
Pre-verify your Brand and Campaign — before the porting is complete, so you’re ready to go the moment the number is live.
Expedite Number Re-linking — once the port is complete, we will update the TCR with your new number’s routing under our account.
Fallback Numbers or Toll-Free Options — to ensure you’re never without a sender ID if timing is critical, we can add a temporarily number to your account to start and expedite the application process.
Notes for Toll-Free Numbers
If you're porting a toll-free number, we’ll update the Responsible Organization (RespOrg) to our designated ID. To avoid service interruption:
Leave the service active for at least 10 days after the port is requested.
Don’t initiate a cancellation with your current provider until the port is confirmed.
⚠️ What If My Number Can’t Be Ported?
While most numbers can be ported to Rally Corp, there are some exceptions. If your number is not eligible, we’ll let you know right away and work with you on alternatives (like registering a new toll-free or 10DLC number).
Frequently Asked Questions
Q: Can I port more than one number?
Yes! You can list up to four numbers on the LOA form. If you have more, simply attach an additional page.
Q: What if I’m unsure of my PIN or account number?
Contact your current provider’s support team or billing portal. This info is required for successful processing.
Q: Will my text campaigns be disrupted?
Nope. We work to schedule the port and complete testing to minimize downtime.
Q: How long will it take to port my number(s)
It can take 5 to 15 business days to port a number, but the process can extend up to 4 weeks or even longer, depending on various factors, including carrier rejections. The responsiveness of your current provider has a significant impact, so please alert them as soon as possible and ensure they are aware of your intention.
Q: What if my number isn’t eligible to be ported?
There are a few common reasons a number may not be eligible:
Carrier Restrictions: Some mobile virtual network operators (MVNOs) or VoIP providers do not support number port-outs or restrict portability.
Wrong Info or Incomplete Records: Missing or incorrect information (e.g. account number, PIN, address mismatch) can block or delay the request.
Unregistered/Inactive Numbers: If the number is inactive, deleted, or not currently assigned, it cannot be ported.
Special Routing or Locked Numbers: Certain numbers are associated with internal routing systems, messaging services, or sub-accounts, which prevent external porting unless explicitly released.
✅ Tip: We recommend contacting your current provider to confirm the number is active, unlocked, and eligible for porting. You can also request a Customer Service Record (CSR) to ensure that all the information matches before submitting your port request.
If you run into any roadblocks, our team is happy to troubleshoot or offer alternative messaging options.
