Porting a number to Zendesk from an external carrier can be a relatively smooth exercise. Just make sure you provide all of the required information and cover all of the bases recommended.

Once the request has been submitted to Zendesk and actioned by a Zendesk Support team member, the estimated porting duration times are as follows:

• US & Canada numbers: approx 1 - 4 weeks
• International numbers: approx 4 - 6 weeks +

Information required for porting:

1. The phone number(s) you want like to port. - If you have more than one, please list all the numbers which you would like to port over to Zendesk.
2. Does the carrier use Twilio?
3. The country for the phone number(s). 
4. Your most recent billing statement for the number.
5. Include the Letter of Authorisation Form. 
   • The above form is available for download at the bottom of this article. Please download the right form for your country.
   • Note: The date on the Letter of Authorization must be be no older than 30 days.
6. If the number to be ported is a cellphone number, you'll need to submit your account details and PIN number in the porting request
7. If the number is going be used for outbound text messages, check you have submitted all of the necessary Regulatory Documentation.
   • Note: If you have already submitted the necessary A2P documentation for outbound texting - when submitting the porting request, confirm that the number will be used for outbound texting to ensure the new number is added to your campaign.

8. Confirmation from the Zendesk account owner to start the porting process.
