Update Contact Details on Indian IDs: 2026 Guide

Why Your Mobile & Email Are Your Digital Keys in 2026

As of October 2026, nearly every government service in India relies on One-Time Passwords (OTPs) for verification. Your registered mobile number and email ID are no longer just contact information; they are the keys to your digital identity. An outdated number can lock you out of crucial services like ITR filing, PF withdrawal, and downloading digital documents. Keeping them updated is essential for security, receiving official communications, and accessing faceless services.

Updating Your Mobile Number on Aadhaar (2026 Process)

Your Aadhaar is the foundational ID, and the mobile number linked to it is the most critical. If this number is wrong or inactive, you must update it first, as many other updates depend on Aadhaar OTPs.

• Process: This update cannot be done online for security reasons. You must visit a physical Aadhaar Seva Kendra (ASK) or an authorized enrolment centre.
• Requirements: No documents are required for a standalone mobile number update. You only need your Aadhaar number and your physical presence for biometric (fingerprint or iris) verification.
• Fee: UIDAI charges a nominal fee for this service. As of late 2026, this is a fixed amount for any demographic update. Always confirm the current fee at the centre or on the official UIDAI website before your visit.
• Email ID: You can typically update your email address at the same time as your mobile number during the same visit.

Updating Contact Info on Your PAN Card

Your PAN is essential for all financial transactions. Having the correct mobile number and email linked is vital for receiving income tax communications and e-verifying your returns.

The Online Process

You can update your contact details on your PAN through the official NSDL e-Gov or UTIITSL portals by submitting a 'Change/Correction in PAN Data' request.

1. Initiate Request: Fill out the correction form online, ensuring you tick the fields for 'Mobile Number' and 'Email ID'.
2. Aadhaar e-KYC: The easiest way to verify is through Aadhaar-based e-KYC. This requires that your desired mobile number is already linked to your Aadhaar to receive the OTP.
3. Payment & Submission: You will need to pay a processing fee online. The fee varies slightly depending on whether you require a physical PAN card dispatch. After successful payment, you submit the application.

If you face issues with the online process, Mahi IT Services offers expert assistance for PAN card corrections to ensure your details are updated smoothly.

How to Update Your Voter ID (EPIC) Contact Details

Linking your mobile number to your Voter ID allows you to download your e-EPIC (a secure PDF version of your voter card) and receive election-related updates. The process is fully online.

• Portal/App: Use the official Election Commission of India portal or the 'Voter Helpline' mobile app.
• Form 8: After logging in, you need to fill out Form 8. This form is used for various corrections, including updating your mobile number and address.
• Authentication: You will need to authenticate your request, often by providing your EPIC number and other details. The new mobile number will be verified via OTP.
• Benefit: Once updated, you can easily download and print your Voter ID from anywhere, a service we can help you with instantly at Mahi IT Services.

Changing Mobile Number on Your Driving Licence & RC

Your mobile number is linked to your Driving Licence (DL) and Vehicle Registration Certificate (RC) through the Parivahan portal. This is crucial for receiving traffic challan notifications and other RTO alerts.

Using the Parivahan Portal

The Ministry of Road Transport and Highways has made this process simple and faceless for most states.

1. Visit the Parivahan Sewa website and select 'Online Services' related to Driving Licence or Vehicle.
2. Find the 'Mobile Number Update' service, which is often listed under 'Other Services' or within your profile.
3. You will need to enter your DL/RC details and authenticate using your Aadhaar number or other credentials.
4. The new mobile number is verified with an OTP before the change is registered.

Contact Details for Business: GST and ITR

For business owners and professionals, keeping contact details updated on tax portals is a legal and practical necessity to ensure compliance.

GST Portal Update

On the GST portal, authorized signatories can update their own mobile number and email ID in their profile settings. The change is verified instantly using an OTP sent to the new number/email. This is essential for receiving all notices and filing verifications.

Income Tax Portal Update

Similarly, on the Income Tax e-filing portal, you can update your primary contact details under your 'My Profile' section. The system will send OTPs to both the old and new numbers/emails to securely confirm the change. This ensures you never miss a communication about your ITR status.

Keeping your contact information current across all documents is a small but vital step in managing your identity in digital India. It prevents delays, secures your accounts, and ensures you have uninterrupted access to government services.
