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

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 Vietnam.

Things to note

For Alphanumeric Sender ID registrations in Vietnam, carriers have strict requirements for Sender IDs as well as message content. The following should be considered if you plan on registering an Alphanumeric Sender ID in Vietnam:

  1. Alphanumeric Sender ID should match company name and/or brand names exactly. In the case that the brand name differs from company name, supplementary official documents should be prepared (please see 'Brand Name Ownership' section below for more details)
  2. Signatories on all documents should match what is documented in the provided business license - in the case that it is not, supplementary documentation should be prepared
  3. SMS templates should always contain the Alphanumeric Sender ID requested - for example, if the sender id requested is Twilio, the SMS template should be something like 'Your Twilio OTP is 123456'
  4. All documentations would require a company stamp to be present, otherwise carriers will reject the customer documentation

Instructions

To register your Alphanumeric Sender ID, Vietnamese mobile network operators require that you provide the following documents:

  • BM02/BM04 document(s)
  • Message Sample Templates

When you have downloaded the forms (either via our Sender ID form, or as attached in this page), please follow these general instructions:

  1. Fill in the yellow highlighted fields—completely replace each field with your own information
  2. If you have questions on how to fill in the required fields, refer to the annotated examples 
  3. Have the documents signed by an authorized signatory of the Sender
  4. Add the Sender’s letterhead and/or logo, and sign where indicated

Vinaphone template for Sample Messages

This template is required by Vinaphone to understand which components/areas of the messages sent out are fixed, and which are variable. For the areas which are variable (changes from message to message), it needs to be marked out using {P.number}.

Every sample message registered can only have a maximum of 3 variable areas.  (You can only have {P1}, {P2} and {P3} at most.) 

Please see the examples below, where the variable components are in bold.

Example 1: OTP Use case

  • Original Message content: Your OTP code on Facebook is 123abc.
  • How to register on template: Your OTP code on Facebook is {P1}.

Example 2: Account Notification Use Case

  • Original Message content: Your order with order number 812567 has been confirmed will be arriving in 35 minutes. 
  • How to register on template: Your order with order number {P1} has been confirmed will be arriving in {P2} minutes.

Business License

We require a colour copy of your business license for the registration. In the case that the business license is only available in black and white originally, black and white will be accepted. In the case that the business license indicates a different name from the requested sender id, please see 'Brand Name Ownership' sections on what would need to be included in your application. 

Please make sure to attach the Business Licence along with the other documents when filling in the Sender ID application.

 

Brand Name Ownership

Carriers in Vietnam are particular in ensuring that the company registering for the Alphanumeric Sender ID owns the sender ID that is being requested.

In the case that the sender id requested does not match the name of the company you are registering with, please prepare some documentation that proves the ownership.

Here are a few types of documents that are accepted by the carriers:

  • Intellectual property certification / trademark documents
  • Certificate of ownership, working relationship with requested brand (these include: agency contract, distribution contract, authorization paper, business franchise, etc)
  • You can also use your website (only for .vn, .com and .com.vn), please provide us one of the following:
    • Domain certificate / contract
    • Extension contract
    • Screenshot of website with information of company
