Online GST Number Verification

Most small and medium enterprises do not want to opt for a GSTIN to avoid the compliance cost that comes with it. However, it is very difficult for businesses to operate without a GST number as nobody wants to deal with an unregistered dealer. This ultimately leads to fake GSTINs being printed on an invoice by such dealers.

GST offers various benefits to businesses and a very important benefit is input tax credit. However, for a business to smoothly avail input tax credit, just being compliant is not enough. It also needs to ensure that its business partners i.e. vendors/suppliers are also GST compliant. If they are not registered under GST and use fake GSTIN on their invoices, your business can face problems while filing GST returns and it will not be able to claim input tax credit. Therefore, it is important for you to verify the GSTIN of all your vendors/suppliers.

It’s an important point to know that GSTIN is of 15 characters which is a combination of numbers and characters. These 15 digits are broken into 5 parts as follows:

  • First 2 digits are state code where the business is registered
  • Next 10 digits are PAN number of the business
  • The 13th digit is registration number of that store or business with same PAN number
  • The 14th digit is Z by default for right now
  • The last i.e. 15th digit is a checksum digit code. It may be an alphabet or a number

Ways in which GSTIN is Misused

Some businesses still don’t have the registration number confirmed, but they have the provisional GSTIN with them, so you can also check the provisional GSTIN online and verify them.

Some shopkeepers and business owners are playing the trick of “I have already applied for GSTIN, Its not yet approved?” This is to give a feeling to customer that they are rightfully charging GST. But this is again a fraud. When they apply for GSTIN, they get a provisional GSTIN anyways and they need to either put a GSTIN or provisional GSTIN on the invoice/bill. Don’t fall for this trap and demand to see the GSTIN.
