# What is Postman SMS?

{% hint style="danger" %}
**ALL Singapore government agencies must use Postman to send out SMSes using the “gov.sg” sender ID** while disseminating official communications to the public. Agency CIOs will be notified of any non-compliance.
{% endhint %}

Postman SMS (also known as Postman v2) is a secure messaging platform developed by Open Government Products that enables government agencies to send mass, personalised communications to the public through SMS.
