Hey bunqers 🌈,
A Tax Identification Number (TIN) is a personal number identifier issued by fiscal authorities in countries where you're a tax resident. Most banks require your TIN immediately, but we give you up to 90 days to submit it — making account set-up easy and stress-free!
Keep in mind: you'll need to provide your TIN for each country where you’re a tax resident, including the country you currently reside in.
Helpful tips 💡
If you’re a tax resident in more than one country, please provide a TIN for each country - this can include countries outside the EEA
Your TIN should contain only alphanumeric characters (no spaces or special characters like - / . )
A personal TIN is for individual tax purposes and is not the same as a business VAT number — for personal account please provide your personal TIN
What happens if you don’t submit your TIN in time?
If you miss the 90-day deadline, your account will be temporarily restricted until you provide your TIN and a valid required document showing your Tax Identification Number.
You can upload this directly in the App or contact our Support Team via the secure, in-app Support chat.

Your TIN: what it is and where to locate it
Name, format and how Tax Identification Number (TIN) is issued can vary by country. In some countries, a TIN is automatically issued at birth, when you register as a resident or when you register with the tax authority. Where you can find your TIN also depends on the country that issued it — it’s often shown on identity documents, official tax documents or government letters.
