Submission to Carrier
CloudTalk submits your request to our partner carrier, who then forwards it to your current provider.

If approved, Cloudtalk team will confirm the porting date (typically 2–4 business days in advance).
If rejected, Cloudtalk team will share the reason and guide you on how to correct and resubmit the request.

Issue | What It Means | How to Fix It |
Mismatched address | The LOA address doesn’t match the current provider’s records | Confirm the registered address with your current provider |
