Whether you are keen to know more about this essential element of the Indian taxation system or you’re a new business owner looking to register for GST, continue reading for more information.

A GSTIN or Goods and Services Tax Identification Number is a 15-digit alphanumeric code that is used to identify registered businesses for taxation purposes. It is given to businesses that generate a revenue of more than Rs.40 lakhs (or Rs.20 lakhs-special category states) in a financial year. Moreover, The GSTIN serves as proof of registration and is applied for various purposes such as filing tax returns, claiming an input tax credit, and compliance verification.

The Structure of the GSTIN is as follows:

  1. In GSTIN, the first two digits represent the state code as per the Indian Census 2011. For instance, 07 represents Delhi, and 27 represents Maharashtra.
  2. The PAN (Permanent Account Number) of the business makes up the next ten digits of the GSTIN.
  3. The thirteenth digit of the GSTIN represents the number of registrations a business has within a state for the same PAN.
  4. The fourteenth digit of the GSTIN represents the entity type of the business. That is, The 14th digit is by default ‘Z.’
  5. The fifteenth digit of the GSTIN is a check digit that is used to detect errors in the GSTIN.

Components of GSTIN

The following are the components of the GSTIN:


1. State Code

The first two digits of the GSTIN represent the state code.

2. PAN

The next ten digits of the GSTIN represent the Permanent Account Number of the business.

3. Registration Number

The thirteenth digit of the GSTIN represents the number of registrations a business has within a state for the same PAN.

4. Entity Type

The fourteenth digit of the GSTIN represents the entity type of the business. The entity type can be proprietorship, partnership, LLP, HUF, company, etc.

5. Check Digit

The fifteenth digit of the GSTIN is a check digit that is applied to detect errors in the GSTIN.

Example: Suppose a business named XYZ Ltd. has its headquarters in Delhi and is registered under GST with a PAN card number ABCCD1234E. This business has only one registration in Delhi, and therefore the 13th digit of the GSTIN assigned to this business will be “1”. The GSTIN for this business will be as follows: 07ABCCD1234E1Z5.

Now suppose that XYZ Ltd. expands its operations and decides to open another branch in Delhi and therefore obtains a second registration in the same state. The 13th digit of the GSTIN assigned to this new registration will be “2”. The GSTIN for this new registration will be as follows: 07ABCCD1234E2Z1.

Similarly, if XYZ Ltd. decides to open a third branch in Delhi, the 13th digit of the GSTIN assigned to this new registration will be “3”, and the GSTIN for this new registration will be as follows: 07ABCCD1234E3Z8.

In this way, a business can have multiple registrations within a state, and the 13th digit of the GSTIN assigned to each registration will indicate the number of registrations the business has within that state for the same PAN.
