​
Initial Overview

​
  1. Supported Number Types

  • Geographic (local) numbers
  • National numbers
⚠️ Mobile numbers are not currently supported for porting.

​
  1. Submit Your Request

Request porting directly in the CloudTalk Dashboard: open Numbers > Port existing number and follow the guided steps. All supported number types for this country use the same flow, and you can track your request anytime under Numbers > Porting requests.

  1. Letter of Authorization

You’ll need to submit a signed Letter of Authorization (LOA). If a template is available for this country, it downloads inside the Documents step of your porting request; otherwise we’ll email you the correct template after you submit. Sign it and upload it with your request. (Other document requirements listed below.)

    For local numbers, also submit the business registration and ID/passport of the signatory
  4. Submission to Carrier
    CloudTalk submits the request to our partner carrier, who forwards it to your current provider
