GST Number, also known as GSTIN, is an important identification number issued to businesses and taxpayers registered under the Goods and Services Tax system. A GSTIN is used for various tax-related activities, including filing GST returns, tracking taxpayer details and claiming input tax credit.
Checking a GST number before doing business with a taxpayer can help you confirm whether the provided GSTIN is valid and whether the basic business details shown on the GST portal match the information given to you.
In this guide, we will explain what a GST number is, why GST verification is important, how to verify GSTIN online and what benefits you can get from checking a GST number.
⭐ What is a GST Number?
A GST Number, officially known as a Goods and Services Tax Identification Number (GSTIN), is a 15-digit unique identification number allotted to a person or business registered under the GST Act.
GSTIN is a PAN-based identification number and is used by the GST system to identify registered taxpayers.
A GST number can be required for several tax-related activities, such as:
- Filing GST returns
- Issuing GST invoices
- Tracking taxpayer information
- Verifying a registered business
- Claiming input tax credit
- Checking GST registration status
- Conducting GST-related transactions
The GSTIN therefore serves as an important identification reference for a registered taxpayer.
GSTIN Format
A GST number consists of 15 characters. The basic structure mentioned in the reference material is:
| Position | Represents |
|---|---|
| First 2 characters | State code |
| Next 10 characters | PAN number |
| Next character | Entity number for the same PAN |
| Next character | Alphabet Z by default |
| Last character | Number or digit used to detect errors |
Because GSTIN contains information connected with the taxpayer’s PAN and registration, checking the number can help confirm whether the details provided by a business are consistent with the GST records.
⭐ Why is GST Verification Necessary?
GST verification is important when you want to confirm the authenticity and validity of a GST number provided by a business or taxpayer.
A GSTIN can be checked before entering into a business transaction, accepting an invoice or relying on GST-related information provided by another party.
The verification process helps you check the taxpayer information available against the GSTIN.
Verify the Authenticity of a Business
A GST number can be used to check whether the taxpayer or business is registered under GST.
This can be particularly useful when dealing with a new supplier, seller, service provider or business partner.
Check Whether the GSTIN is Valid
GST verification helps you determine whether the GSTIN entered on the portal is valid.
If the number is not valid, the details may not match the information expected from a registered taxpayer.
Avoid Errors in GST Details
Incorrect GST numbers can create problems in invoices and tax-related records. Verifying the number before using it can help identify possible errors.
Maintain Transparency
GSTIN verification provides access to basic taxpayer information available through the GST system. This can make business transactions more transparent.
Help With Input Tax Credit
A valid GSTIN is important when dealing with transactions involving GST and input tax credit. Checking the GST number can help ensure that the GST details being used in a transaction are correct.
⭐ How to Verify GST Number Online?
GST number verification can be completed online using the GST portal.
You generally need the GSTIN or UIN that you want to check.
Follow these steps to verify a GST number:
Step 1: Visit the GST Portal
Visit the official GST portal to begin the GST number verification process.
Step 2: Open Search Taxpayer
On the GST portal, look for the “Search Taxpayer” option available in the top menu.
Select the option to search using GSTIN/UIN.
Step 3: Enter GSTIN or UIN
Enter the GST number or UIN that you want to verify in the required field.
You may also need to enter the captcha displayed on the screen.
Step 4: Submit the Search
After entering the required details, click on the Search button.
The portal will process the information you have submitted.
Step 5: Check the Displayed Details
After the search is completed, the GST portal can display information associated with the entered GSTIN.
You can check details such as:
- Business or taxpayer name
- GST registration status
- Address
- Other available registration details
Compare these details with the information provided by the business.
If the displayed information does not match the information on the invoice or documents, you should carefully check the GSTIN again for typing or other errors.
⭐ What Details Can You Check Through GSTIN Verification?
GSTIN verification is useful because it allows you to compare the GST number with the taxpayer information available through the GST system.
Depending on the information displayed by the portal, you may be able to check:
| Detail | Purpose |
|---|---|
| GSTIN/UIN | Identifies the GST registration |
| Business/Taxpayer Name | Helps verify the registered entity |
| Registration Status | Helps check whether the GST registration is active or otherwise shown on the portal |
| Address | Helps compare the registered business information |
| Other available details | Provides additional information associated with the registration |
It is important to carefully compare the information rather than checking only the GSTIN digits.
⭐ Benefits of Checking GST Number Online
There are several reasons why a business or taxpayer may want to verify a GST number before proceeding with a transaction.
1. Authenticity
GST verification can help check the authenticity of the taxpayer or business associated with a GSTIN.
2. Validity
It helps you check whether the GSTIN entered into the GST portal is valid and what registration information is associated with it.
3. Tax Credit
Checking GST details can be useful when dealing with transactions where input tax credit is involved. It helps ensure that the GST information used in the transaction is accurate.
4. Invoice Verification
GSTIN verification can help identify mistakes in GST numbers before they are used on invoices or other tax-related records.
5. Transparency
The availability of taxpayer information through the GST system can help improve transparency in business transactions.
6. Fraud Detection
Checking GST details before a transaction can help identify inconsistencies between the GSTIN and the information provided by a business.
7. Error Identification
A single incorrect digit in a GSTIN can cause the number to be different from the intended registration. Verification provides an opportunity to identify such errors.
⭐ GST Number Verification for Business Transactions
Businesses often exchange GST invoices and tax information with suppliers, customers and service providers.
Before relying on a GST number, you can compare the GSTIN entered on the invoice with the information available through GST verification.
For example, if a supplier provides a GST invoice, you can check:
- GSTIN mentioned on the invoice
- Registered business or taxpayer name
- Registration status
- Address and other available information
- Whether the details correspond with the supplier information
This simple checking process can help reduce errors in GST-related records.
⭐ What to Do If GSTIN Details Do Not Match?
Sometimes, the GSTIN provided by a business may not match the information displayed after verification.
There can be different reasons for this, including:
- GSTIN may have been entered incorrectly.
- One or more characters may have been typed incorrectly.
- The business may have provided an incorrect GST number.
- The invoice may contain outdated or incorrect information.
- The information may require further checking through the GST system.
If you notice a mismatch, it is better to verify the GSTIN again and compare all available details before relying on it for a transaction.
⭐ GST Number Verification and GST Invoices
GSTIN plays an important role in GST-related invoicing.
When dealing with a GST invoice, checking the GST number can help you identify potential mistakes in the taxpayer information.
For businesses, maintaining accurate GST information is important because incorrect details can create problems when preparing tax records and filing GST-related documents.
Therefore, GSTIN verification can be treated as a useful checking step before relying on the GST details provided by another taxpayer.
⭐ How Long Does GST Number Verification Take?
GSTIN verification is an online process and can generally be completed quickly.
The basic process involves entering the GSTIN or UIN, completing the captcha if required and submitting the search request.
Once the result is displayed, you can compare the available taxpayer information with the details provided by the business.
⭐ What is the Difference Between GST Number and GSTIN?
The terms GST Number and GSTIN are commonly used to refer to the same 15-digit identification number allotted to a taxpayer registered under GST.
GSTIN stands for Goods and Services Tax Identification Number.
Therefore, when someone asks for a business’s GST number, they are generally referring to its GSTIN.
