GSTIN (Goods and Services Tax Identification Number) is the identification number given to every person registered under GST. In your business dealings, especially with new suppliers, you may want to verify GSTIN quoted by your supplier. Under GST, as your input credit depends upon your supplier’s compliance, it is important to ensure that the GSTIN quoted by your supplier is genuine. End consumers may also face situations where they doubt the correctness of the GSTIN quoted in a supplier’s invoice and would like to verify the details. In the past, certain cases have also been reported where suppliers who are not registered under GST have mentioned a fake GSTIN in invoices and collected tax. In an earlier blog, we have discussed the structure of GSTIN, which can be a first-level check to ensure that your supplier’s GSTIN is as per the prescribed structure. In addition, for a fool-proof check, the GSTN portal has given a ‘Search Taxpayer’ service, using which you can verify the details of any GSTIN.
