Porting Process Overview

  1. Submit Your Porting Request
    Submit your request in the CloudTalk Dashboard under Numbers > Port existing number.
  2. Initial Review
    The CloudTalk team will verify number portability and confirm the next steps.
  3. Documentation Collection
    Complete and sign the LOA (Letter of Authorization), and provide a recent invoice from your current telecom provider.
  4. Submission to Carrier
    CloudTalk submits your request to our partner carrier, who then forwards it to your current provider.
  5. Approval or Rejection
    • If approved, the CloudTalk team will confirm the porting date (typically 2–4 business days in advance).
