Porting virtual numbers from existing provider to Sinch

rms-ak — Wed, 29 Oct 2025 02:32:15 GMT

Hello Sinch community,

Currently my employer is in the process of transitioning from Burst SMS/Kudosity to Sinch for our SMS/messaging services. What would be the best course of actions to take in terms of porting our existing virtual numbers from Kudosity to Sinch, without causing major interruptions to operations?

Regards,

Adhy

Hi Shahzad,

We have customers using virtual numbers from multiple regions including North America, Oceania, Asia and Europe. Do you require a full list?

Hello,

The process to port numbers to Sinch varies by country. In North America, you can fully move the number from your current service provider to Sinch (called porting, this will also move your voice service), or you can move just the messaging service (called hosting). Both porting and hosting can be managed in the Sinch Dashboard for North American numbers, but if you do have any questions, you can contact our Customer Support team (email support@sinch.com) for additional help.

Please note that US numbers, sometimes referred to as 10DLC, require a campaign so to avoid service interruptions, please be sure your campaigns are fully vetted, approved and in your Dashboard account prior to initiating the porting or hosting process.

For RoW porting (Rest of World), there are many variations of the process to port numbers to Sinch. Some countries have strict documentation requirements and in order to determine portability, we will need the full list of numbers. I did confirm your organization has an active Sinch Dashboard account so we encourage you to work with your Account Manager or Sales Lead to initiate the porting process and minimize any potential service interruption.

Thank you,

Heidi
