Are shortcode messages (5-6 digits) supported with 2nd Phone Number?

Created by Support Team, Modified on Wed, 13 Mar 2024 at 05:50 PM by Support Team

While the Second Phone Number App offers many benefits, it's important to understand its limitations. Unfortunately, sending messages to shortcodes is not currently supported.

Here's why:

  • Second Phone Number utilizes Voice over Internet Protocol (VoIP) technology. This differs from traditional cellular networks used by shortcodes.
  • Shortcodes are designed to interact with specific cellular networks and may not recognise or respond to messages sent from VoIP numbers.


  • If you need to use a shortcode, you might consider: Using a traditional mobile phone number or contacting the service or organization associated with the shortcode directly to inquire about alternative methods.

We're always working to improve:

  • We understand this limitation might be inconvenient. We're continuously exploring ways to expand Second Phone Number's capabilities and potentially offer shortcode support in the future.
