A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

Documents Required and Instructions to Register Your Alphanumeric Sender ID in Russia

Before we begin


Notice: IMPORTANT! As of 11th of March, registration for Russia Sender ID-s has been temporarily put on hold. If you are related with humanitarian aid and in line with the work of our Twilio.org team, then please reach out to us at senderid@twilio.com and we will review your application individually

Due to regulatory requirements, there is sometimes a need for documents to be signed by customers to ensure that registrations are done on behalf of customers that have the right to use the Sender ID. This serves to ensure that traffic is coming from legitimate sources and minimizes any potential misuse.

This article outlines the documentation requirements for a pre-registration in Russia.

Things to note

Space is not allowed in the sender name. 


To register your Alphanumeric Sender ID, the Russia network operators require that you provide the following document: 

  • Business Registration License 
  • Web domain certificate (For senders that are related to websites)

Upload the forms to the Twilio Alphanumeric Sender ID Registration Form.
