What is number porting?

Number porting transfers your existing phone number from your current carrier to Allo. Your number stays the same, Allo just becomes your new provider.

How it works

1

Fill out the porting form

Go to porting.withallo.com and submit your details. We’ll need information from your current provider, see the checklist below before you start.
2

We handle everything with your carrier

Our team contacts your current provider and initiates the transfer on your behalf. No calls or paperwork on your side.
3

We confirm your porting date

We coordinate the exact transfer date and let you know as soon as it’s confirmed. You can request a preferred date, note it’s not always guaranteed.
4

Prepare 24h before

The day before the transfer, your number appears in your Allo account. Use that window to configure your settings so everything is ready on day one.
5

Activation day

Your number goes live with no downtime. Log in, open and close the app once to make sure everything is working smoothly.
Do not cancel your current service until the porting is complete. Your number must stay active with your old provider for the transfer to succeed. Cancelling early releases the number and breaks the port.

​
What you’ll need

Before filling out the form, contact your current provider to gather:
InformationWhere to find it
Account numberYour carrier bill or online account
Authorized person nameMust match the name on the billing contract exactly
Billing phone numberOn file with your current carrier
Service addressZip code and state are required
Port-out PINRequest it from your carrier, not always required, but avoids rejections
Last invoiceA copy of your most recent bill
The most common reason for a rejected port is a name mismatch. Make sure the authorized person name matches your carrier contract exactly.

​
Costs

Allo charges nothing to port your number. Your ported number is included in your existing plan with no extra monthly fee. Your current carrier may charge an early termination or port-out fee, check your contract before initiating. If you already have an Allo number, your ported number either replaces it or becomes an additional number at the standard rate.

​
Limitations to know before porting

Allo numbers cannot receive OTP (One-Time Password) messages. If your number is currently used for two-factor authentication with banks, WhatsApp, Uber, Airbnb, or similar services, keep a separate number active for that purpose. This limitation applies to most virtual and VoIP services.
Old voicemails and texts don’t transfer. Export anything you need from your previous provider before the cutover. Contacts can be imported into Allo separately. Outgoing SMS can be delayed up to 48 hours during the cutover window as carriers update routing.

​
10DLC & Brand Registration (US numbers)

If your number already has an A2P 10DLC registration with your current provider, it does not transfer to Allo. You’ll need to re-register.
  1. Go to Settings > Compliance in your Allo dashboard
  2. Register your Brand (one-time $24 fee)
  3. Create a Low Volume campaign once approved
Approval takes 3–7 business days. Start early to avoid any SMS interruption.

​
Common issues

The most common causes are a name mismatch, wrong account number, outstanding balance, or an active contract. Verify all details match your carrier records exactly, then resubmit.
Check your most recent carrier bill, log into your carrier’s online account, or call their customer service directly.
Email us at [email protected] and we’ll check the status with your carrier.
You can. Your number stays fully active with your current carrier until cutover day. Most customers experience no service disruption.
Yes. You’re always in full control of your number and can port it out to another provider at any time.
Yes. Once the port is complete, your number moves to Allo and your previous carrier’s service for that line ends. This means any plan tied to that number (calls, texts, mobile data) will no longer be active with your old provider.This is standard for any number port between carriers, not specific to Allo.If you’d rather keep your current carrier, you can use call forwarding instead of porting. Call forwarding redirects your incoming calls to your Allo number so you get AI summaries, recordings, and CRM sync, while keeping your existing plan active.Keep in mind that call forwarding only covers incoming calls. You won’t be able to make outbound calls from that number through Allo, and forwarded calls will not appear as outgoing activity in your Allo account. It’s a great option if you want to keep your carrier and still benefit from Allo’s features on calls you receive.
