13 Nov GST Registration Amendment: New 3-Day OTP Rule 2026
GST Registration Amendment: New 3-Day OTP Verification Rule Effective from November 2026
The Goods and Services Tax (GST) registration process in India has undergone an important change from 1 November 2026.
Under the revised GST registration amendment process, taxpayers must complete the prescribed mobile number and email address OTP verification within three days of submitting the applicable amendment application.
This change is important for businesses that want to update their GST registration particulars, such as business names, partner details, directors or additional places of business.
Failure to complete the required OTP verification successfully within the prescribed period means that the Application Reference Number (ARN) will not be generated.
Let’s understand the revised process, verification requirements and important points every GST-registered business should know.
1. What Is the New GST Amendment Rule?
The Central Government issued Notification No. 05/2026-Central Tax dated 26 October 2026, introducing changes to the provisions relating to GST registration amendments under Rule 19 of the CGST Rules, 2017.
GSTN subsequently issued an advisory dated 1 November 2026 confirming that the corresponding changes had been implemented on the GST portal.
One of the key requirements is mandatory online verification of the relevant registered mobile numbers and email addresses through OTP authentication.
Taxpayers are provided three days from the date of submission of the amendment application to complete the prescribed verification successfully.
If the verification is not completed within this period, the ARN will not be generated.
2. Which Details Require OTP Verification?
Under the revised procedure, online verification is mandatory for the mobile number and email address of:
- The Primary Authorised Signatory.
- One selected Promoter, Partner, Director, Karta, Member, Trustee or other applicable person.
The exact applicable person depends on the constitution and details of the registered business.
The verification process ensures that the relevant authorised persons can be authenticated through their registered contact details.
3. What Is the Three-Day OTP Verification Deadline?
After submitting the applicable GST registration amendment application, taxpayers are provided three days to complete the required OTP authentication.
For example:
Suppose a business submits its GST registration amendment application on 10 November 2026.
The prescribed OTP verification must be completed within three days of submitting that application.
If the required verification is not successfully completed within the prescribed period, the GST portal will not generate the ARN.
Therefore, businesses should ensure that their registered mobile numbers and email addresses are active and accessible before submitting an amendment application.
4. What Happens If OTP Verification Is Not Completed?
Failure to complete the required OTP verification successfully within the three-day period has an important consequence.
The Application Reference Number (ARN) will not be generated.
Without successful completion of the prescribed authentication and other applicable online validations, the amendment process cannot proceed through the normal portal workflow.
This means that businesses should not assume that submitting the amendment application alone completes the process.
They should also monitor their registered mobile numbers and email addresses and complete the verification promptly.
5. Does Every GST Registration Amendment Require Officer Approval?
Not every amendment follows the same approval process under the revised procedure.
The treatment depends on the type of registration detail being changed.
A. Principal Place of Business Amendment
Changes relating to the Principal Place of Business (PPOB) will continue to be examined by the Proper Officer in accordance with the applicable provisions of Rule 19.
Therefore, these amendments do not become automatically approved merely because the application is submitted.
B. Other Registration Amendments
For several other registration changes, including:
- Change in the legal name of the business.
- Addition, deletion or retirement of partners.
- Changes in directors or Karta.
- Addition of an Additional Place of Business.
- Other applicable registration particulars.
The registration certificate will stand amended upon submission and successful completion of the prescribed online verification and validations, as applicable.
The portal also validates PAN, DIN and CIN wherever applicable.
This makes it important to provide accurate information and upload the necessary supporting documents while submitting FORM GST REG-14.
6. How to Complete GST OTP Verification?
Taxpayers can complete the prescribed OTP verification through the GST Common Portal.
Follow these steps:
Step 1: Visit the official GST portal at https://www.gst.gov.in.
Step 2: Navigate to Services.
Step 3: Select Registration.
Step 4: Open OTP Verification of GSTIN.
Step 5: Enter the required GSTIN and follow the prescribed authentication process.
Step 6: Complete mobile and email OTP verification for the applicable authorised persons.
Step 7: Ensure that all required online validations are successfully completed.
The OTP verification service is also available through:
https://services.gst.gov.in/services/otpVerification
Taxpayers should complete this process within three days of submitting the applicable amendment application.
7. What Should Businesses Do to Avoid Verification Issues?
Businesses should take a few precautions before submitting an amendment application.
- Ensure that the Primary Authorised Signatory’s mobile number is active.
- Verify that the registered email address is accessible.
- Coordinate with the selected Promoter, Partner, Director or other applicable person.
- Keep the required supporting documents ready.
- Check all business and registration particulars before submission.
- Complete the prescribed OTP verification without waiting until the last day.
- Check the GST portal for successful validation and ARN generation.
These steps can help reduce unnecessary delays during the amendment process.
8. Why Is This GST Update Important for Business Owners?
GST registration details are essential for maintaining accurate business records and complying with GST requirements.
A business may need to amend its registration when there are changes in its legal name, business structure, partners, directors or additional business locations.
With the revised process, online OTP verification has become an important step for applicable amendment applications.
Business owners should therefore coordinate with their authorised signatories and other selected persons before initiating the amendment process.
