How to Apply for a UIN to Sell on Thotfy (Via GST Portal)

Updated on February 7, 2026

Time taken to get UIN Number: 10 mins

If you're a non-GST registered seller looking to sell on Thotfy (an E-Commerce Operator), you are required by law to generate a User ID (UIN) on the GST Portal. This helps ensure compliance under GST rules for selling through platforms like ours.

Why Do I Need a UIN?

Even if you’re not GST registered, the Government of India requires sellers on e-commerce platforms to register as “unregistered suppliers” and obtain a UIN for Tax Collected at Source (TCS) reporting.

🔒 This doesn’t mean you’re registering for GST — it just gives you a unique user ID to legally sell through Thotfy.

Step-by-Step: Apply for UIN Online

Direct link to apply:
👉 Generate UIN on GST Portal

Step 1: Fill in User Credentials

Go to the link and fill in the following:

Name as per PAN: Full legal name
PAN Number: Enter your 10-digit PAN (apply if you don’t have one)
Primary Email & Mobile Number: For OTP verification
State: Choose the state where you operate or ship from
Secondary Email & Mobile (Optional): For backup communication

Step 2: Provide Address Details

You can use the map to auto-locate your address, or fill it manually:

PIN Code, State, District, City
Locality, Road/Street, Building Name/Number, Floor, Landmark

This should be your pickup address, where shipments will be collected.

Step 3: Add Goods or Services You Supply

You must list the top 5 goods you intend to sell. Use the official GST portal to search for the correct HSN (Harmonized System of Nomenclature) Codes:

🔍 Search HSN/SAC Codes Here:
👉 https://services.gst.gov.in/services/searchhsnsac

Example:

For handmade bags: Search “Handicraft Bags”
For wall decor: Search “Home Decor” or “Metal Artwork”

🧾 Choose the HSN codes carefully — these help identify what you sell and ensure compliance.

Step 4: Complete Captcha & Submit

Thotfy uses your UIN to comply with TCS filing requirements
You can now start selling legally on the platform

📌 Important Notes

This UIN is not a GSTIN
It is only for unregistered sellers using e-commerce platforms
Apply once per state from which you plan to ship products
