Question

How many alpha numerals are there in the format of GSTIN?

Answer 1

The GSTIN (Goods and Services Tax Identification Number) is a 15-character alphanumeric code used to identify businesses registered under GST.

Structure of GSTIN:

1. First 2 characters → State code (Numeric)
2. Next 10 characters → PAN (Permanent Account Number)
   • First 5 characters → Alphabetic
   • Next 4 characters → Numeric
   • Last 1 character → Alphabetic
3. 13th character → Entity code (Numeric)
4. 14th character → Always “Z” (Alphabetic)
5. 15th character → Check digit (Alphanumeric)

Number of Alphanumeric Characters in GSTIN:

• PAN (10 characters) → 6 Alphabets + 4 Numerals → Alphanumeric
• 14th character (Z) → Alphabet
• 15th character (Check Digit) → Alphanumeric
• 1st, 2nd and 13th characters → Numeric

Total Alphanumeric Characters in GSTIN:

10 (PAN) + 1 (14th Character “Z”) + 1 (15th Character - Check Digit) = 12

∴ There are 12 alphanumeric characters in the GSTIN format.
