How porting works
The flow depends on the type of number you’re porting. Pick the matching option below.- 🇺🇸 US, Canadian & international numbers
- 🇫🇷 French numbers
Carrier-coordinated porting
For US, Canadian, and other international numbers, Allo coordinates the port with your current carrier on your behalf.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.
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.
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.
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.
What you’ll need
Before filling out the form, contact your current provider to gather:| Information | Where to find it |
|---|---|
| Account number | Your carrier bill or online account |
| Authorized person name | Must match the name on the billing contract exactly |
| Billing phone number | On file with your current carrier |
| Service address | Zip code and state are required |
| Port-out PIN | Request it from your carrier, not always required, but avoids rejections |
| Last invoice | A copy of your most recent bill |
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.Eligible numbers

I need to use my number during porting
I need to use my number during porting
You can. Your number stays fully active with your current carrier until cutover day. Most customers experience no service disruption.
Can I port my number back out later?
Can I port my number back out later?
Yes. You’re always in full control of your number and can port it out to another provider at any time.
Will I lose access to my current carrier after porting?
Will I lose access to my current carrier after porting?
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.
