What is GSTIN?

GSTIN, or Goods and Services Tax Identification Number, is a 15-digit unique identification number which is assigned to all registered taxpayers. Generally, this number is given to suppliers, dealers, or businesses.
Previously, state VAT law was used to register businesses. Then, they had another unique ID, which was a Tax Identification Number (TIN). This number was provided to them by state tax authorities. Now, with GST being a centralised regime, the GSTIN is a replacement for the TIN, which is provided by the centre.
GSTIN Number Example
All GSTIN has a specific structure which follows a pre-defined style, as shown in the table below:
Digits of GSTIN | What They Denote |
First 2 digits | State code which follows the Indian Census 2011. |
Next 10 digits | PAN (Permanent Account Number) of the entity/ business. |
13th digit | Number of entities registered within a state. |
14th digit | Default value, which is currently “Z”. |
15th digit | Code meant for detection of error. |
Let us take an example to understand this better. Suppose a GSTIN is 27AAAPA1234A1Z5. The denotation for each individual character is as follows:
- 27 is the state code of Maharashtra, where the business is present.
- AAAPA1234A is the business’s PAN.
- 1 denotes that this is the first business registration in Maharashtra under this PAN.
- Z is a reserved character by default.
- 5 is a code for error detection.
