Unlike a standard GSTIN (GST Identification Number), which is assigned to registered taxpayers, the UIN is issued to specific persons or entities who are not liable to pay GST but are eligible to receive a refund of taxes paid on inward supplies. Understanding what UIN under GST means, who qualifies for it, and how it works is crucial for organizations like embassies, consulates, and UN bodies operating in India. ## What Is UIN Under GST? **UIN** stands for Unique Identification Number, a special 15-digit alphanumeric code assigned under GST to notified bodies who are not taxpayers but are eligible to receive refunds on the tax paid on inward supplies of goods and services. These entities operate under international or diplomatic privileges and are often exempted from paying taxes as per bilateral agreements or global treaties. The structure of UIN is similar to GSTIN: - First two digits: State code - Next ten digits: PAN or unique code assigned to the entity - Last three digits: System-generated sequence ## Who Can Apply for a UIN? UINs are issued under [**Section 55 of the CGST Act**](https://busy.in/gst/gst-fundamentals-all-about-goods-and-services-tax-in-india/) to the following entities: - Specialized UN agencies (e.g., UNICEF, UNDP) - Multilateral financial institutions (e.g., World Bank) - Foreign embassies and consulates - Any other person notified by the GST Commissioner ## Why Is UIN Important Under GST? While these entities are not required to register for GST, they still pay GST on local purchases. The UIN helps them: - Claim refunds on GST paid - Comply with diplomatic and treaty obligations - Ensure accurate and traceable transactions with suppliers **Key Benefit:** It minimizes tax leakage and ensures input tax tracking without making the entity a taxpayer.

It contains: - Invoice-level details of purchases - Supplier GSTIN and tax amounts - Refund amount claimed **Note:** Refund claims must be filed within 2 years from the end of the quarter in which the supply was received. ## UIN vs GSTIN: Key Differences | Criteria | UIN (Unique Identification Number) | GSTIN (GST Identification Number) | | --- | --- | --- | | Purpose | Refund on inward supplies | Tax collection and compliance | | Registration Form | GST REG-13 | GST REG-01 | | Return Filing | GSTR-11 | GSTR-1, GSTR-3B, GSTR-9, etc. | | Tax Liability | No | Yes | | Eligibility | Foreign bodies, UN, embassies | Regular business taxpayers | **Tip:** Suppliers must mention the UIN correctly in invoices for a successful refund process. ## Conclusion The Unique Identification Number (UIN) under GST enables exempted entities like embassies, UN bodies, and foreign organizations to claim tax refunds without becoming regular taxpayers. This supports diplomatic relations and ensures transparency in domestic taxation. By following the correct application process, filing GSTR-11 timely, and maintaining invoice-level documentation, UIN holders can effectively recover GST and comply with Indian tax laws. **Read More –** [**How to Register for GST in India**](https://busy.in/gst/how-to-register-for-gst-in-india-a-step-by-step-guide/) ## About the author **Rithesh Bajoriya** As a Chartered Accountant with over 18 years of experience, I have honed my skills in the field and developed a genuine passion for writing.
