How to Call DKB (Deutsche Kreditbank) From Abroad
8/3/2026
Quick answer: For a blocked card, suspected fraud, or a trading/securities issue, call DKB at +49 30 120 300 00 from anywhere in the world. This isn't a general "ask us anything" line, DKB routes everyday account questions to its in-app AI chat first. Dial the number over Wi-Fi from your browser with DialVia to avoid roaming charges.
DKB is built around app-first support, with one real phone number behind it
DKB (Deutsche Kreditbank) is a popular secondary account for expats, largely because of its no-foreign-transaction-fee card. But it's also one of the more app-first German banks: DKB's official contact page leads with an AI chatbot for general questions, and the phone number it publishes is scoped specifically to account/card blocking, suspected fraud, and securities-trading problems, not routine banking questions.
That's still exactly the kind of call you don't want to be stuck without a working number for while you're abroad.
The verified international number
| Purpose | Number | Notes |
|---|---|---|
| Card/account blocking, suspected fraud, trading issues | +49 30 120 300 00 | Per DKB's official contact page |
For anything else, DKB's own guidance is to use the secure message inbox in the DKB app or online banking, since there's no general customer-service phone line published for routine questions.
What to have ready before you call
- Your account number or IBAN
- Your card number, if the call is about a blocked or compromised card
- Details of the suspicious activity: merchant, amount, and time, if fraud-related
- Access to the DKB app, in case you're asked to confirm something through it during the call
Best time to call
This line handles urgent issues, so it's worth calling as soon as you notice a problem rather than waiting for German business hours. If your issue isn't urgent, the in-app chat is available around the clock and is DKB's preferred first contact.
- UK: Germany is 1 hour ahead.
- US East Coast: Germany is 6 hours ahead, so late morning German time lines up with your early morning.
- UAE/Gulf: Germany is 2 to 3 hours behind.
