You apply for ID Austria in three steps: online pre-registration with A-Trust, a free appointment at a registration authority (Registrierungsbehörde) with photo ID and a smartphone, and activation of the app at home. Registration is free, and ID Austria is valid for five years.

Whether you are applying for the first time, need to re-link ID Austria after switching phones, or want to know what the EU Digital Identity Wallet actually changes for you, this guide walks through every step and edge case — including whether foreigners living in Austria can get an ID Austria at all. Many people handle other financial decisions in the same appointment window, for example checking our credit guide for Austria.

Key takeaways

• ID Austria is free and applied for in 3 steps: pre-registration with A-Trust → appointment at a registration authority → app activation at home.
• Valid for 5 years; renewal only works before expiry and only for the full function (Vollfunktion) — the basic function (Basisfunktion) cannot be renewed.
• Available without Austrian citizenship if you have a "sufficient connection to Austria" (ausreichender Bezug zu Österreich) — relevant for Germans and other expats resident in Austria.
• EU member states must offer a Digital Identity Wallet by the end of 2026; public bodies must accept it from 1 January 2027, and private companies in regulated sectors follow roughly a year later.
• The qualified electronic signature attached to ID Austria already lets you complete many official processes digitally and with full legal validity.

What is ID Austria?

ID Austria is the country's digital identity for the internet. It replaced the earlier mobile signature (Handy-Signatur) on 5 December 2023 and is now the standard way to log into FinanzOnline (the tax portal), the digital driving licence, numerous municipal and regional government portals, and a growing number of private online services that require secure identification.

At its core sits the qualified electronic signature. According to the Federal Chancellery (Bundeskanzleramt), this signature is legally equivalent to a handwritten signature across the EU, subject to the exceptions listed in Austria's Signature and Trust Services Act (Signatur- und Vertrauensdienstegesetz). That means you can sign forms, applications and contracts with full legal effect without printing anything.

There are two levels: the basic function (identification only, no legally valid signature) and the full function with the qualified signature attached. Most official processes, and the process described in this guide, refer to the full function, since only it is issued in person at a registration authority and can later be renewed.

How to apply for ID Austria: step-by-step

The application runs in four stages and is free for everyone eligible.

Step 1 — Online pre-registration. At a-trust.at/id-austria-vorregistrierung, enter your ID details and mobile number. This saves time at the in-person appointment because your data is already on file.

Step 2 — Book an appointment. You need an in-person appointment at a registration authority: a municipal office (Magistrat), local council (Gemeinde), tax office (Finanzamt) or police station (Polizei). Bring:

• an official photo ID (passport or national identity card)
• a current passport photo, but only if you do not already hold a valid Austrian ID document
• a smartphone with biometric capability (fingerprint or face recognition)

Step 3 — At the appointment. The authority verifies your identity, prints an activation code (Freischaltcode) and revocation password (Widerrufspasswort), and records your mobile number for SMS one-time codes.

Step 4 — Activate at home. On a second device (PC, laptop or tablet), go to a-trust.at/id-austria-registrierung or ida.gv.at, enter the activation code and password, and link the "ID Austria" app or another second factor to your smartphone.

Eligibility: Minimum age 14; Austrian citizenship is not a strict requirement — a "sufficient connection to Austria" is enough. That opens ID Austria to non-citizens living in Austria too. Cost: none, the entire process is free of charge.

Applying for ID Austria without a smartphone, or as a foreigner

Without a suitable smartphone: The app-based second factor is the standard route but not the only one. If you do not own a suitable smartphone, ask the registration authority about an alternative when booking your appointment — available options can vary by location, so it is worth clarifying with the specific office beforehand.

As a German citizen or other foreigner (expats): As noted above, Austrian citizenship is not a requirement. What matters is a "sufficient connection to Austria" — the registration authority assesses this case by case; a registered residence (Meldezettel) is the most obvious example. If you live in Austria and want to use FinanzOnline, the digital driving licence or other e-government services, you go through the same four-step process as Austrian citizens. Bring a valid official photo ID from your home country to the appointment — since you are unlikely to hold an Austrian ID document, you will also need a current passport photo.

Renewing ID Austria: validity, deadlines, expiry

The full function of ID Austria is valid for 5 years from issue. Renewal is free and done online, but only while your current ID Austria has not yet expired — once it lapses, the only option is a full new application with another in-person appointment.

Important: the basic function cannot be renewed. Only the full function, issued in person at a registration authority, can be renewed online. If you originally switched from the mobile signature to ID Austria, you carry over the remaining validity of your original mobile signature certificate — so the five-year clock does not necessarily restart on the date you switched.

According to media reports (including itwelt.at and kosmo.at, 2026), around 300,000 ID Austria certificates expire in 2026. This figure comes from trade press coverage, not an official government statement, but it signals that checking your own expiry date in good time is worth doing. Check your personal expiry date directly in the app or on ida.gv.at, and start the renewal process well before the deadline.

Switched phones? How to transfer your ID Austria

A new smartphone does not mean another trip to a registration authority. Pair the "ID Austria" app on the new device using a second device (PC, laptop or tablet): open the pairing process at ida.gv.at/app and either scan the displayed QR code or enter the one-time code shown in the new app.

A mobile number recorded at registration is an important safety net here: if you are logged out of the app and no other second factor is available, an SMS one-time code sent to that number serves as a fallback. Keep your registered number current, especially if you also change your phone number itself.

Troubleshooting ID Austria: common errors and the power-of-attorney feature

"ID Austria not working" or login errors: The most common causes are an expired certificate, a missing or incorrectly paired second device after a phone switch, or an outdated app version. Check for an app update first, then your expiry date in your account settings on ida.gv.at.

Power-of-attorney feature (Vollmacht): Account management for ID Austria includes a menu item called "Manage powers of attorney" (Vollmachten verwalten). This feature officially exists and is confirmed on ida.gv.at. For the exact process — who can act on whose behalf and for which official processes — check directly with ida.gv.at or the relevant authority for your specific situation before setting one up.

If nothing works: Technical support is available via the help pages on id-austria.gv.at, and a registration authority can assist in person with persistent problems.

The EUDI Wallet: what the EU's digital wallet means from 2026/2027

The EU Digital Identity Wallet (EUDI Wallet) is not a single deadline — it is a multi-stage rollout with three distinct dates that are frequently confused with one another.

Legal basis: The eIDAS 2.0 reform, Regulation (EU) 2024/1183, was adopted by the European Parliament on 2 March 2024 and has been in force since April 2024.

Date 1 — member states' obligation to provide a wallet: Every EU member state must offer citizens at least one EUDI Wallet by the end of 2026 (sources vary between "December 2026" and the Austrian finance ministry's "autumn 2026" phrasing; Germany plans a concrete start from 2 January 2027).

Date 2 — public-sector acceptance obligation: From 1 January 2027, public bodies must accept the wallet for identification. This is the date media coverage often shortens to "the EUDI Wallet starts" — but it only covers the obligation for public authorities to accept it, not the point at which citizens can first get one, which comes earlier.

Date 3 — private-sector acceptance obligation: Private companies in regulated sectors (banks, insurance, telecoms, energy, transport, healthcare) only need to accept the wallet roughly a year later, around 2028.

Austria's position: According to the Austrian Federal Ministry of Finance (BMF, March 2024), ID Austria "already fulfils all the prerequisites for use as an EU wallet." The digital driving licence is planned to gain EU-wide validity from autumn 2026, positioning Austria as one of the frontrunners in the wallet rollout. However, according to press reports from June 2026, no single EU member state had fully implemented the certified wallet requirement by that point, and no binding public start date for a certified EUDI Wallet in Austria had been confirmed. Implementation is proceeding gradually through the existing ID Austria infrastructure — anyone who already holds a valid ID Austria is well positioned for that transition.

Using ID Austria day to day: credit and health insurance, sorted digitally

If you are already updating your digital identity, it is often a natural moment to sort out other financial decisions too. Whether a personal loan or supplementary health cover makes sense depends on your individual situation — our guides give you the basis for that decision.

For a loan comparison, our credit guide for Austria walks through several providers and their terms, including loan brokers such as GIROMATCH. If you are looking for supplementary health cover, the health insurance guide for Austria covers benefits and costs. Both topics stand entirely apart from ID Austria itself, but many people prefer to handle digital admin and financial decisions in the same sitting.

You can check loan options directly here as well: check car and personal loan conditions at durchblicker.at (ad) or loan brokerage via GIROMATCH (ad).

If you are looking for a new current account (Gehaltskonto) instead, our bank account comparison for Austria covers the main options, and a broader overview of loan offers is available in our loan comparison for Austria. ID Austria is also your login for the annual tax return via FinanzOnline — more on that in our Austrian tax return guide.

Frequently asked questions about ID Austria

Häufig gestellte Fragen

How much does ID Austria cost?

Nothing. Pre-registration, the in-person appointment and app activation are all completely free, as is renewal before expiry. There are no fees at the municipal office, local council, tax office or police station.

How long does it take for ID Austria to become active?

After your appointment, ID Austria is active as soon as you enter the activation code and password at home on a-trust.at or ida.gv.at and link the app. The in-person appointment itself takes varying amounts of time depending on the office and demand.

Can I apply for ID Austria without an appointment?

No, an in-person appointment at a registration authority is required because your identity must be verified face to face. Online pre-registration with A-Trust does not replace the appointment, it only shortens it.

Can I apply for ID Austria as a German citizen or other foreigner?

Yes. Austrian citizenship is not a requirement — a sufficient connection to Austria is enough — for example a registered residence; the authority assesses this case by case. Bring a valid official photo ID from your home country and a current passport photo to the appointment.

What happens if my ID Austria expires?

Renew it online before it expires, which is free, but only for the full function. If it has already lapsed, the only option is a completely new application with another in-person appointment.

How do I transfer ID Austria to a new phone?

Open the ID Austria app on your new smartphone and pair it via a second device at ida.gv.at/app using a QR code or one-time code. A registered mobile number acts as an SMS fallback during this process.

What is the difference between the basic and full function?

The basic function only handles identification and cannot be renewed. The full function also includes the qualified electronic signature, is legally valid for signing documents, and can be renewed online as long as it has not yet expired.

Will the EUDI Wallet replace my ID Austria?

Not in the short term. According to the BMF, ID Austria is being expanded gradually into an EU wallet. Public bodies must accept such wallets from 1 January 2027, while private companies in regulated sectors follow roughly a year later.

Conclusion: ID Austria is your key to digital admin in Austria

Applying for ID Austria costs nothing beyond one appointment and a few minutes of activation at home — in return, it opens access to FinanzOnline, the digital driving licence and a growing range of private services. The important thing is keeping the five-year clock in view, since only the full function can be renewed online before it expires.

Three points worth remembering: registration is possible without Austrian citizenship given a sufficient connection to Austria, switching phones does not require another in-person appointment, and the EUDI Wallet arrives in three separate stages between the end of 2026 and roughly 2028, not on a single date.
