Foreign nationals in Türkiye (Turkey) may need a potential tax identification number for banking, insurance, vehicle, notary, title deed, fee payment and other official procedures. This guide explains what the number is, why it matters and how to apply through the Digital Tax Office.
What is a potential tax identification number?
It is a tax identification number used to identify foreign individuals who do not yet have Turkish tax liability or a Turkish identity number in official systems. It does not automatically mean that the person has become a taxpayer in Türkiye; it mainly enables accurate identification for applications and payments.
Why may it be required?
Banks, notaries, insurers, title deed offices, public fee systems and vehicle-related payment channels may ask for this number. It can be especially useful for foreigners who enter Türkiye with a foreign-plated vehicle, apply for insurance, pay traffic fines, pay residence permit fees or complete other public payments.
How to apply online
- Open the Revenue Administration Digital Tax Office.
- Choose the potential tax identification number application service for foreigners.
- Fill in the requested identity and contact fields.
- Confirm that the information is accurate.
- Submit the application and save the number shown on the screen.
Information usually requested
- Name and surname
- Gender and country information
- Foreign identity number, if available
- Place of birth and parent names
- Passport number
- Mobile phone number
- Address to be used in Türkiye
Enter the details exactly as they appear in the passport and official documents. A wrong passport number or name spelling may cause problems in banking, insurance, notary or public procedures.
Where is it used?
It may be needed for opening a bank account, issuing an insurance policy, foreign-plated vehicle procedures, traffic fine or motor vehicle tax payments, residence permit fee payments, notary procedures, title deed transactions and other official applications.
Why is it important for insurance processes?
In traffic insurance, kasko, extended liability or roadside assistance quote/policy processes related to foreign-plated vehicles, the person must be identified with consistent identity or tax information. If a foreigner does not have a Turkish identity number, a foreign identity number or a potential tax identification number may be used. Correct identity, passport, plate and chassis details help prevent policy, payment, claim and official-record problems.
Can it be obtained through e-Government?
The main application channel is the Revenue Administration Digital Tax Office. e-Government also provides tax number verification services, but the practical application flow is handled through the Digital Tax Office. Screen names and requested fields may change over time, so the current Revenue Administration Digital Tax Office screens should be treated as the source of truth before applying.

FAQ
Does obtaining a potential tax ID make someone a taxpayer?
No. The number helps identify a foreign person in official Turkish systems. Tax obligations depend on the transaction and applicable law.
Why can it matter for foreign-plated vehicle insurance?
Insurance quote/policy and official payment processes may need to match passport, plate, chassis/VIN and policy information to the correct person. If there is no Turkish ID number, a foreign ID number or potential tax ID may be used.
Should I apply again if a number already exists?
Usually it is better to check the existing number through the Digital Tax Office query/verification service instead of creating conflicting records.
Does Gurbet Kasko issue this number?
No. The potential tax identification number is issued or queried through the official Digital Tax Office. Gurbet Kasko and Özhedef Sigorta Aracılık Hizmetleri are not tax authorities.
Keep your passport and contact details ready. The transaction is completed through the official Digital Tax Office.
