eID in Germany: How to Activate and Use Your Electronic ID

Your German residence permit or ID card is sitting in your wallet doing about 10% of what it could. The chip inside it is a government-verified digital identity that can replace most of your trips to the Bürgeramt. If you haven’t activated it yet, you’re leaving a genuinely useful tool completely unused.

What Is the eID Function?

The eID (elektronische Identität) is a chip embedded in two specific documents: the German Personalausweis (national ID card, for German citizens) and the elektronischer Aufenthaltstitel or eAT (electronic residence permit, for non-EU residents).

When you use it, your card and phone communicate via NFC to prove your identity to a digital service, the same way a contactless bank card works, but for identity verification. It’s legally binding, encrypted, and far more secure than emailing scanned copies of your documents.

Who Can Use eID in Germany?

Non-EU expats with an eAT, and German citizens with a Personalausweis. That covers the vast majority of expats reading this.

If you’re an EU citizen living in Germany, you keep your home country’s ID or passport, you don’t receive a German Personalausweis. Whether your home country’s ID card works with German eID services depends on your country. Most EU national IDs do not integrate with the AusweisApp or German government portals. Check with your home country’s authority if unsure.

If you’re a non-EU national with an eAT, your card has the eID chip built in and you’re fully supported.

What You Need Before You Start

• An NFC-enabled smartphone: most phones made after 2016 have this. Check Settings → Connections → NFC. If your phone doesn’t support NFC, a USB NFC card reader (€15–25 on Amazon) connected to a laptop works just as well.
• The AusweisApp: download the official government app on iOS or Android. Don’t use third-party alternatives.
• Your Transport-PIN letter: when you received your eAT, a separate letter arrived by post containing a 5-digit Transport-PIN. You need this to set your own 6-digit PIN. If you’ve lost it, you’ll need a Bürgeramt visit to get a new one.

How to Activate Your eID Step by Step

1. Open AusweisApp and tap “Set up online ID function.”
2. Remove your phone case, then place your eAT flat against the back of your phone over the NFC sensor.
3. When the app detects the card, enter the 5-digit Transport-PIN from your letter.
4. Choose a new 6-digit PIN and confirm it. Store it in a password manager: never keep it in your wallet with the card.

The whole process takes about three minutes once you have everything ready.

How to Reset or Change Your PIN

Enter the wrong PIN three times and the card locks. To unlock it you need the PUK, also printed in the original letter from when you received your eAT.

If you’ve lost both the PIN and the PUK, there’s no shortcut: visit the Ausländerbehörde in person and ask for a new PIN letter.

To simply change a PIN you already know, do it directly in the AusweisApp under settings, no office visit needed.

What Can You Actually Use eID For?

• BundID: Germany’s central login for government services. Register once with eID and access dozens of federal and state portals without separate logins.
• ELSTER, the official tax portal for your Steuererklärung. eID login is faster and more reliable than the certificate-file method.
• Opening bank accounts online, several banks including N26 and DKB accept eID verification in place of the VideoIdent webcam call.
• Ausländerbehörde online services: some immigration office portals allow eID-authenticated document uploads and applications.
• University enrollment: many German universities use eID for student registration and digital records.
• Deutsche Post / DHL: age and identity verification for special parcel pickups.

Using eID on a Laptop

You don’t need a smartphone. A USB NFC card reader (around €15–25) connected to your laptop, with AusweisApp installed on the computer, works identically. Place your card on the reader when prompted. This is particularly useful for ELSTER tax submissions on a desktop.

Common Problems and Fixes

Card not detected: Remove your phone case, confirm NFC is enabled in settings, and hold the card completely still. The NFC antenna on most phones sits in the upper third of the back panel.

“Connection lost” error: Don’t move the card mid-read. Hold it flat and steady for a full 5–10 seconds until the app confirms the connection.

Card blocked: Three wrong PIN attempts lock the card. Use the PUK from your original letter to reset. Without the PUK, visit the Ausländerbehörde.

Service not accepting eID: Not every German website supports eID, only those that have integrated the official government gateway. Look for the AusweisApp logo or “Online-Ausweis” option on the site.
