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

Before we begin

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 Turkey.

Things to note

  • Promotional traffic is not allowed
  • If the Sender ID does not match the company name, a formal document (trademark registration, official website, etc.) would be required to show the linkage between company name and brand name

Instructions

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

  • Company/Brand Registration Certificate
  • Customer to Twilio LOA
  • Customer to Twilio Authorization Letter

To get you up and running as quickly as possible, please fill out the document completely and accurately and provide any other required information. Use the examples provided for guidance. Note that mobile network carriers are very strict about the details! We highly recommend that you download the examples (hit right click, and select 'Save Image As...') and do a side by side comparison when you are filling out the documents.
