“Can I port my Canadian phone number (with a Canadian area code) to a US-based phone service provider?”
You do not have to give up the number merely because a company is U.S.-based: some services expressly accept Canadian numbers. The hard part is whether that service accepts your exact number and whether its type of phone service meets your needs.
The deciding question is whether the receiving service supports **Canadian numbers**, not whether the company is based in the United States.
You can seek to your number into a U.S.-based service that offers Canadian-number transfers. Zoom Phone expressly supports existing U.S./Canadian numbers in most cases and tests individual numbers; Twilio also lists Canadian local and mobile numbers, subject to area coverage. Your transferred number remains your Canadian number. [Zoom](https://zoom.us/phone-number-porting) · [Twilio](https://www.twilio.com/en-us/guidelines/ca/porting)
If you have an eligible Google Voice business account, its administrator can request a Canadian-number transfer; Google says wireless transfers are available in Canada. For a U.S.-billed Voice Premier account, Google imposes a matching-area-code porting-address condition for assigning a transferred number to a Canadian user. This is **not** the personal Google Voice procedure. [Google business instructions](https://knowledge.workspace.google.com/admin/voice/port-business-numbers-to-google-voice)
If you are a U.S.-based personal Google Voice user, a Canadian mobile number does not meet Google's requirement for an **active U.S. mobile phone number**. More generally, the FCC cautions that keeping a number when changing providers may not be possible after moving to a new geographic area. [Google personal instructions](https://support.google.com/voice/answer/1065667) · [FCC](https://www.fcc.gov/consumers/guides/porting-keeping-your-phone-number-when-you-change-providers)
Keeping a Canadian number is different from turning it into a U.S. number; moving to another calling area can affect whether a particular transfer works. [CRTC](https://crtc.gc.ca/eng/phone/mobile/num.htm)
These steps use Zoom Phone as a concrete Canadian-capable example; keep your current line active until the transfer completes.
Before starting any transfer
Keep the Canadian line active and collect its account details
Do not cancel the Canadian line yourself. Zoom's U.S./Canada transfer instructions require the existing account details and a four-digit PIN for wireless transfers; the CRTC says the new provider should arrange the switch.

条件要求
Before paying for a new plan
Test whether the number is eligible
Use Zoom's public local-number checker at https://zoom.us/phone-number-porting for an initial check; it checks the first six digits, not the complete transfer request. The later **Check Portability** control in the Zoom account tests the full number. If that full-number check rejects it, this Zoom route does not preserve the number.

条件要求
Before submitting the transfer
Activate a Zoom Phone plan
Purchase a Zoom Phone plan and complete its initial setup; Zoom requires an active phone license and number-management permissions for its transfer process. As a published price example, its US & CA Unlimited plan lists **USD $18 per user per month billed monthly**, or **$16 per user per month billed annually**, at https://www.zoom.us/pricing/zoom-phone. The cited instructions do not establish a separate port-in fee.

条件要求
While the Canadian line is still active
Submit the complete-number transfer request
In Zoom's Admin Center, select **Product configuration → Numbers → Phone Numbers → Add Number → Port Number**. Choose local numbers, enter the entire Canadian number, select **Check Portability**, and complete the online using the existing provider's invoice; then submit. Zoom lists **up to 15 business days** for number porting, not a guaranteed deadline.

条件要求
Before relying on the new service
Update your emergency location and confirm the transfer
Set or update your registered emergency location in Zoom Phone when using it from your U.S. address, then confirm the transferred number works. Zoom says an internet outage can interrupt its calling, including 911, and a transferred cellphone number no longer has the old cellular service.

This answer draws on the CRTC and FCC consumer guidance and the receiving providers' own Canadian-number transfer instructions.
CRTC, Switch providers and keep your number
The Canadian regulator says to leave the old service active and have the new provider arrange the transfer.
Keep your phone number when you switch
Most importantly, do not cancel your service before you switch to the new provider. Tell your new phone provider that you want to keep your number.
CRTC, Switch providers and keep your number
Changing geographic areas can limit whether a Canadian number can be retained.
You might need to get a new phone number
If you move to a different province or “local calling area”. If you’re unsure, please contact your new service provider.

The U.S. regulator does not promise number retention when someone changes geographic areas.
If you are moving to a new geographic area, you may not be able to keep your current phone number when changing providers.

A U.S.-billed Voice Premier business account faces a specific Canadian-number assignment condition.
Canada
If you're a Voice Premier user in North America and are porting in Canadian numbers, if their billing location is in the U.S., the porting address must match the area code of the number being ported. If it doesn't, you can't assign the ported number to a Canadian user.
Twilio, Canada: Porting Guidelines
Even a Canadian-capable provider may be unable to accept a specific number.
Restrictions
Most numbers are portable. In rare cases, Twilio may not have rate-center (geographic) coverage for particular phone numbers.
Zoom, Purchasing and assigning Zoom Phone licenses
Moving a cellphone number into Zoom Phone changes it into a Zoom Phone number, not continuing the old mobile line.
Porting
When a cell phone number is successfully ported into Zoom, that number becomes a Zoom Phone number. You will no longer have cellular service.
Zoom Phone 911 Customer Notification
Zoom warns that an internet interruption also interrupts its emergency calling.
If the Internet connection over which Zoom Phone Service is provided is interrupted, you **will not** have access to Zoom Phone Service, including 911 service, during that interruption.
Zoom Phone 911 Customer Notification
A person using Zoom Phone from a new address must update the location used for emergency calling.
If a user attempts to use Zoom Phone Service from a different location, i.e., not their primary work station, they will be prompted to update their Registered Location.
Zoom Phone Pricing
Zoom publishes an example phone-plan price; its cited transfer guidance does not establish a separate transfer charge.

Zoom, United States (US) & Canada phone number requirements
Zoom lists a lead time for U.S./Canadian number transfers, not a guaranteed completion date.
