Sender ID Guidelines

Alphanumeric Sender ID

It is mandatory to use an alpha sender id when sending messages to Austria.

*All alphanumeric Sender IDs (the business name shown at the top of an SMS message) used to send messages to Austrian mobile numbers must be pre-registered in the official Sender ID directory managed by RTR-GmbH. If your Sender ID is not registered, your messages will be blocked and will not be delivered to Austrian recipients from 1 October 2026.

Key Dates

  • 1 July 2026 — Registration portal opens
  • 21 August 2026 — Deadline to submit existing sender data (Official date is 24 August 2026 for one time bulk submission but we need 1 business day to prepare the file for submission)
  • 1 October 2026 — Blocking begins for unregistered sender IDs 
Numeric Sender ID

Numeric sender IDs are not supported unless offered by Vonage's 2-way service.

The numeric Sender IDs will be overwritten to ensure delivery.
Generic Sender ID Generic sender IDs such as INFO, SMS, NOTICE etc are prohibited. Please use a representative brand name or business name as your alpha sender id.
