Is your mobile number registered with GST no longer accessible? Perhaps you've changed your phone number, or the one linked to your GSTIN belongs to someone who is no longer associated with your business. Whatever the reason, having an outdated mobile number on the GST portal can lead to a lot of inconvenience, as crucial notifications, OTPs for various transactions, and important communications from the tax authorities are sent to this registered number. But don't worry, changing your mobile number on the GST portal is a straightforward process that can be done online. This comprehensive guide will walk you through every step, ensuring a smooth and hassle-free update.
Why is an Accurate Mobile Number on GST Portal Crucial?
Before we dive into the "how-to," let's quickly understand why maintaining updated contact information, especially your mobile number, on the GST portal is so vital:
Essential Communications: The GST department uses your registered mobile number and email ID as primary channels for sending important updates, notices, and compliance reminders.
OTP-Based Authentications: Many critical actions on the GST portal, such as filing returns, making payments, or updating details, require OTP verification, which is sent to your registered mobile number.
Avoiding Compliance Issues: Missing out on crucial communications due to an outdated number can lead to penalties, late filings, and other compliance issues.
Account Security: An updated mobile number enhances the security of your GST account by ensuring that only you receive verification codes.
Prerequisites for Changing Your Mobile Number
Before you begin the process, ensure you have the following ready:
Your GSTIN: Your Goods and Services Tax Identification Number.
Login Credentials: Your username and password for the GST portal.
Access to Current Registered Mobile Number/Email ID (if possible): While the aim is to change the number, in some scenarios, you might initially need access to the old number/email for OTP verification, especially if the authorized signatory details remain the same.
The New Mobile Number: The number you wish to register.
Digital Signature Certificate (DSC) or Electronic Verification Code (EVC): Required for submitting the amendment application. DSC is mandatory for companies and LLPs, while EVC can be used by proprietorships and partnerships.
Now, let's get to the step-by-step guide!
Step 1: Initiate the Login and Navigation
Ready to get this done? Let's start by accessing the GST portal. This is where your journey to updating your contact details begins!
1.1 Access the GST Portal
Open your web browser and go to the official GST portal: www.gst.gov.in.
1.2 Log In to Your Account
On the GST Home page, locate and click the "Login" button.
Enter your Username (your GSTIN) and Password.
Complete the CAPTCHA verification by entering the characters displayed.
Click "Login" to access your GST dashboard.
1.3 Navigate to Amendment Section
Once logged in, from the main menu, click on "Services".
Hover over "Registration" and then click on "Amendment of Registration Non-Core Fields".
Note: Mobile number and email ID updates fall under 'Non-Core Fields', meaning they generally don't require approval from a tax officer, and the changes are usually immediate or very quick after successful submission.
Step 2: Identify Your Scenario and Proceed Accordingly
The process for changing your mobile number slightly differs based on whether the authorized signatory whose details you wish to change is the same person as the promoter/partner or if there are multiple authorized signatories, or you're adding a new authorized signatory.
Scenario A: Authorized Signatory is the same as the Promoter/Partner
If the person whose mobile number needs updating is also the proprietor or a designated partner/promoter, follow these steps:
2A.1 Select "Promoter/Partners" Tab
On the "Amendment of Registration Non-Core Fields" page, click on the "Promoter/Partners" tab.
2A.2 Edit Details
Locate the authorized signatory (which is you, in this case) whose details you wish to change.
Under the "Actions" column, click on the "Edit" button next to their name.
2A.3 Update Mobile Number
In the editable fields, enter the new mobile number you wish to register. You can also update your email address here if needed.
Click on "Save" to confirm the changes.
2A.4 OTP Verification
The system will send an OTP (One-Time Password) to both the old (if accessible) and the new mobile numbers, and potentially to the old and new email IDs.
Enter the received OTPs in the respective fields to validate the changes.
Click "Proceed".
Scenario B: Authorized Signatory is different, or you're adding a New Authorized Signatory
If your business has multiple authorized signatories, or you need to add a new person whose mobile number will be the primary one, follow these steps:
2B.1 Go to "Authorized Signatory" Tab
On the "Amendment of Registration Non-Core Fields" page, click on the "Authorized Signatory" tab.
2B.2 Add New Authorized Signatory (If applicable)
If you are adding a completely new authorized signatory whose mobile number you want to use, click on the "Add New" button.
Enter all the required details of the new authorized signatory, including their new mobile number and email address.
Click "Save".
2B.3 Deselect Old Primary Signatory (If necessary)
Wait for approximately 15 minutes after saving the new signatory details.
Log out and log back into the GST portal.
Navigate back to "Services > Registration > Amendment of Registration Non-Core Fields" and then to the "Authorized Signatory" tab.
Deselect the checkbox next to the previously designated primary authorized signatory.
2B.4 Select New Primary Signatory
Select the checkbox next to the newly added or updated authorized signatory whom you want to set as the primary authorized signatory.
Verify that the new mobile number and email address are correctly displayed.
An OTP will be sent to the new mobile number and email ID for verification. Enter these OTPs to confirm.
Step 3: Final Verification and Submission
Regardless of which scenario applies to you, the final steps involve verification and submitting your application.
3.1 Navigate to "Verification" Tab
Click on the "Verification" tab.
3.2 Declaration and Place
Tick the declaration checkbox, confirming that all the information provided is true and correct.
In the "Name of Authorized Signatory" dropdown, select your name (or the name of the authorized signatory).
Enter the "Place" (city/town where the application is being filed).
3.3 Submit the Application
Choose your desired submission method:
Submit with DSC (Digital Signature Certificate): If you are a company or LLP, you will likely need to use a DSC. Select this option and follow the prompts to digitally sign the application.
Submit with E-Signature: This option uses Aadhaar-based e-sign.
Submit with EVC (Electronic Verification Code): If you are a proprietorship or partnership, you can use EVC. An OTP will be sent to the updated mobile number and email ID (if changed) for verification. Enter the OTP to complete the submission.
3.4 Confirmation and ARN
Upon successful submission, a confirmation message will be displayed on the screen.
You will also receive an Application Reference Number (ARN) via SMS to your newly updated mobile number and an email to your updated email ID. This ARN is crucial for tracking the status of your application.
Step 4: Monitor Application Status
While non-core amendments are generally processed quickly, it's a good practice to monitor the status.
4.1 Track Your Application
You can track the status of your application by logging into the GST portal and navigating to "Services > User Services > Track Application Status".
Enter your ARN and click "Search".
4.2 Confirmation of Changes
Once the changes are successfully processed and approved (which often happens instantly for non-core fields), you will receive a confirmation message, typically indicating "Changes Approved" or similar. Your updated mobile number will then be reflected on your GST profile.
Key Considerations
Prompt Updates: Always update your contact information promptly to ensure you don't miss any critical communications from the GST department.
OTP Issues: If you encounter issues with receiving OTPs, double-check the entered number, check your spam folder for emails, and try again. If problems persist, contact the GST helpdesk.
No Offline Process: Changing your mobile number in the GST portal is an online-only process through the amendment facility.
