Quiet hoursNo window recorded

All alphanumeric Sender IDs must be registered in RTR's public Sender ID register. Since 1 October 2026, messages with unregistered alphanumeric Sender IDs are blocked by Austrian operators. Each Sender ID must clearly identify the sending business and be supported by a justification (e.g. company name or trademark). RTR review takes up to 14 days, during which the Sender ID may be delivered as "Unknown".

What this market refuses

Sender IDs must be 1–11 characters and contain at least one letter. Only A–Z, a–z, 0–9, spaces and the characters + - & _ are permitted. Umlauts (ä, ö, ü), ß, accented letters and all other special characters (e.g. . ! @ ' /) are not allowed, nor are leading or trailing spaces. Generic names (e.g. Restaurant, Reminder, Shop, Alert) are not permitted unless backed by a registered trademark. Marketing messages require prior opt-in consent and must include an opt-out option.

Sending to Austria, answered

Common questions about sender registration, two-way replies, and compliance when launching SMS in Austria.

Do I need to register a sender before sending SMS to Austria?

Registration is required for an alphanumeric sender ID. No registration is required for a long code; confirm availability, ownership and destination access before sending. Approval does not preserve the submitted sender ID for an alphanumeric sender ID; it is still overwritten after approval. For an alphanumeric sender ID the name itself is registered. Confirm how the approved sender is presented on the destination networks.

Can I use an alphanumeric sender ID in Austria?

You can submit an alphanumeric sender ID after approval, but the carrier still overwrites it before delivery.

How long does sender registration take in Austria?

The recorded estimate for an alphanumeric sender ID is about 14 business days; confirm timing before launch.

Can I receive replies from Austria?

No. You can send messages here but not receive replies.

Are there quiet hours for SMS in Austria?

No country-wide sending window is recorded here. Confirm the rules that apply to your message purpose and recipient location.

What content is restricted in Austria?

Messages about Political, religious, gambling and betting, and adult and unsolicited promotional content are restricted.

Do I need consent before messaging someone in Austria?

Yes. The recipient must opt in before you send the first message. Provide an appropriate opt-out route and honor the recipient’s preferences.
