.at domains with umlauts: spelling, Punycode and email

atdomain.at Editorial · 5 min · Updated 25 October 2026

The essentials

A .at domain can contain permitted international characters. Technical systems use an ASCII representation, often recognisable by xn--. The umlaut spelling and a version using ae, oe or ue are separate names. Check their availability individually and test website and email separately rather than assuming identical support.

Two neutral address cards with blue dots, a globe and a connecting bridge — Readable and technical representations can identify one name. A spelling using ue is a separate domain.

1. Separate the spelling from its technical representation

An international domain may appear both in a readable umlaut form and in a technical representation of the same name. The conversion is called Punycode. An address spelling out ue, however, is not an automatic redirect for the version with ü. Keep the intended spelling and its corresponding technical form in your project notes. Our search converts international names for technical checking. That does not establish that every possible character sequence is registrable. Review the displayed result and complete name before ordering. Avoid copying unfamiliar characters from a third-party message into your final address.

2. Check each variant for a specific purpose

Think about how people encounter the address: on a sign, in conversation or through a clickable link. Someone familiar with an umlaut name may type it differently from a person using another language’s keyboard. Check the written-out version separately if it would help your audience. Two domains also have separate terms and costs. Avoid buying numerous spellings without a purpose. Decide which address will be primary and what a second one would actually do. Redirecting it requires suitable configuration at the website service; registering a second name does not create the redirect.

Assess other spelling variants deliberately

3. Test input on real devices

Enter the chosen address on a phone and a keyboard your visitors actually use. Ask another person to write it after hearing it aloud. Check that copying it from an invitation produces the same address. If the browser displays the technical form, compare it with your saved domain rather than guessing a similar spelling. Test short entries without www where you advertise them. Record troublesome cases. These checks should help you decide for your actual audience; they do not establish that umlaut domains are always good or always bad.

4. Check email as a separate connection

A successful website visit is not an email test for the same domain. Ask your chosen mail service which international spelling it supports and how it appears in account settings and recipients’ programs. Test sending and receiving with the programs actually used before approving stationery or signatures. An additional ASCII domain may be practical for certain contact routes, but it is a separate registration. atdomain.at does not sell mailboxes. Connect a separately obtained mail service using its required DNS values. Follow the service’s current instructions rather than changing several unfamiliar values at once.

Plan a domain for email

5. Keep the exact name for technical tasks

For DNS records, certificates and a later handover, make it clear which address an instruction concerns. Separate the main address, www and any other names used. If a service requires the ASCII form, use the verified representation of your domain rather than inventing the sequence after xn--. Record where the active DNS zone is managed. With our default nameservers, use DNS management in your account; with custom nameservers, use their associated management service. After connecting, test the actual HTTPS address and the separate email route. A visible list of records does not replace that functional check.

6. Budget for each registered name

A standard new .at domain costs €12.99 total for one year; annual renewal currently costs €15.99 total. Alternatively, a new .at domain has a 3-year plan for €39.00 total, including registration and two annual renewals without further payment during the included term. Save €5.97 against €44.97 with annual payments at today’s prices. Afterwards, renewal uses the offer then available; there is no automatic card charge. If you buy two spellings, budget for each separately. Hosting and mail services may add their own charges.

Compare current total prices

Before publication: make one clear decision

Choose the main address using your input and connection tests. Check possible naming rights separately from technical availability. Before paying, review the displayed domain and term, then wait for registration confirmation. Record which spelling you will publish and which additional variant, if any, will redirect. Printed materials, the website and contact details should reflect that deliberate choice. If a result or technical spelling remains unclear, clarify it through the support center before ordering. One understandable, maintained main address is more useful than a collection of untested variants.
