Viber Operator Templates

Last updated: 6 October 2026

Viber
An operator template is a message template containing text and variables that is submitted to Viber for registration. Once registered, the template serves as a basis for creating custom templates and helps reduce the cost of informational and service messages.

Operator templates cannot be used to send messages. Create a custom template based on it.

    The template is tied to the sender’s name—only the operator templates that you create and register for the sender’s name selected here will be available later for creating a custom template for that same sender.

  4. Enter a clear and informative template name that reflects its content. Use only lowercase Latin letters, numbers, and the underscore character—no spaces.

  5. Select the Operator template type.

  6. From the drop-down list, select the two-letter language code for the template. The code should match the language of the template text.

  7. Enter the template text for Viber messages.

    info

    Viber operator templates and custom templates based on them can contain text only. The maximum text length is 1,000 characters. Buttons, images, and files are supported only in free templates.

  8. Place the cursor where you want the variable to appear and click to add a variable to the template.

    What are variables used for?

    Variables are values in a template that can change, such as the recipient’s name, order number, delivery date, or service name. For example, in the template:

    Hello, {1}! Your order No. {2} will be delivered on {3} at the delivery point

    {1} is the recipient’s name, {2} is the order number, and {3} is the delivery date.

    When sending a message, you can replace the variables with the appropriate values. For example:

    Hello, Anna! Your order No. 1244 will be delivered on October 15 at the delivery point

    tip

    When creating a custom template, you can replace a template variable with a recipient variable or fixed text.

  9. (Optional) Place the cursor where you want the emoji and click to add it to the template.

  10. Review the message in the preview window and click Submit to open the form with the variables found in the template.

  11. In the Used variables section, specify:

    • Variable name — the name in Latin characters without special characters.
    • Variable sample — the value you plan to send to the recipient.

  12. Click Submit to submit the template for registration with Viber.

The template will change to the status

Pending registration
. Registration takes approximately 1–2 days. The template’s status is displayed in the general list of templates.

After successful registration, the template will receive the status

Active
and will become available for creating custom templates.
