On July 27, 2025, the Unique Identification Authority of India (UIDAI) has scheduled a significant system maintenance activity that will affect all Aadhaar-related online services for up to 20 hours. This temporary outage includes services through the MyAadhaar portal, mAadhaar mobile app, and several authentication-based operations. While this initiative is aimed at improving system reliability, it will also impact millions of users who rely on Aadhaar for banking, identification, and government services.
Here’s everything you need to know about this scheduled downtime, its implications, and how to prepare ahead of time.
🛠️ Why Is This Maintenance Happening?
All major digital infrastructure systems—especially those operating at a national scale like UIDAI—require regular upgrades and preventive maintenance. The key reasons behind this 20-hour downtime include:
- Server infrastructure upgrades to ensure faster and more secure service delivery
- Database optimization and system cleanup
- Strengthening security protocols to defend against cyber threats
- Preparing the system for upcoming feature updates or policy implementations
- Enhancing user interface responsiveness and backend performance
Regular maintenance of this kind is vital for UIDAI to deliver consistent, safe, and efficient services to over a billion Indian residents.
📅 Maintenance Schedule: Key Details
- Date: Saturday, July 27, 2025
- Duration: Up to 20 hours (exact time not officially disclosed)
- Affected Services: All Aadhaar-linked online services, including the MyAadhaar portal and the mAadhaar app
Though UIDAI has not announced the exact start and end times, users are advised to treat the full day as unavailable for Aadhaar-related online operations.
🚫 What Services Will Be Affected?
Here’s a list of the Aadhaar services that will not be accessible during the maintenance window:
- Downloading or retrieving e-Aadhaar (PDF or masked version)
- Updating demographic details such as name, mobile number, and address
- Submitting biometric update requests through the portal or app
- Using OTP-based or biometric-based Aadhaar authentication
- Checking Aadhaar linking status with PAN, bank accounts, or mobile numbers
- Services on the mAadhaar app
It is important to note that some Aadhaar Seva Kendras (enrolment and update centres) may still remain open, though their ability to perform real-time authentication or updates might be limited.
📌 How It Affects Users
For many individuals, Aadhaar is not just an identity number—it is integrated into essential services such as banking, insurance, telecom, government welfare schemes, scholarship registrations, and more. A sudden disruption can cause real setbacks.
Here are the possible consequences during the downtime:
- Delay in bank transactions requiring Aadhaar e-KYC or OTP-based verifications
- Postponement of government services such as ration distribution, LPG subsidy verification, or pension processing
- Interruptions in telecom activations or SIM card linking with Aadhaar
- Inability to perform urgent demographic or biometric updates
- Delays at service centers where verification requires UIDAI API responses
Service providers like banks, telecom operators, and government departments that depend on live authentication may see disruptions or slower processing.
✅ What You Should Do Before July 27
To avoid being impacted by the scheduled service outage, here are some essential steps to take ahead of time:
- Download your e-Aadhaar in advance: Save a PDF copy on your phone or computer and print a hard copy for emergencies.
- Complete all updates early: Whether it’s a change in address, mobile number, or other demographic data, do it before the maintenance period.
- Finish Aadhaar-based verifications: If you’re planning on opening a new bank account or submitting Aadhaar for a KYC requirement, get it done a day earlier.
- Inform dependents: Make sure senior citizens or rural residents relying on Aadhaar-based services are informed about the outage.
- Verify important logins: Many financial apps or services use Aadhaar-based OTP login. Ensure that all critical setups are handled in advance.
- Use alternate IDs: If required, keep PAN cards, passports, or driving licenses ready as backup identification documents.
🏦 Are Offline Services Still Available?
While physical enrolment centres and Aadhaar Seva Kendras may continue to function, their effectiveness will depend on whether they rely on online authentication. Here’s what may still work:
- Manual document collection for updates
- Biometric enrolment or demographic update scheduling (may be saved for later processing)
- Support for forms or grievances
However, Aadhaar verification, OTP generation, and biometric checks performed in real-time through the UIDAI servers will likely be down during this window.
🔐 Security and Transparency
UIDAI has emphasized that this planned maintenance is in line with its commitment to system security and user trust. Aadhaar data, which includes sensitive identity and biometric records, is protected under the Aadhaar Act, 2016. UIDAI must ensure its servers are regularly patched and optimized to meet national security and data privacy standards.
In the past, UIDAI has carried out minor upgrades that resulted in partial service disruptions. However, this is one of the rare instances where a nearly full-day, all-platform blackout has been pre-announced.
Such proactive communication is an indicator of improved transparency and planning, aiming to minimize user discomfort and operational friction.
📝 Update Policy Reminders
- Users can update Aadhaar details online without any fee until June 14, 2025.
- After this date, all online updates will be discontinued, and physical visits to centres will be mandatory. A small service fee may apply.
- Demographic updates (name, gender, date of birth, address) are generally processed within 30 days.
- Biometric updates (photo, fingerprints, iris) usually take longer and always require in-person verification.
💡 Expert Tips to Stay Ahead
- Schedule Aadhaar-dependent errands wisely: Either do them before July 27 or postpone until services resume.
- Use printed Aadhaar copies: For any essential verification, carry your Aadhaar printout or download it before the deadline.
- Check UIDAI website or helpline (1947): Stay updated on any schedule changes or extended outages.
- Use alternate identity proofs: For banking, ticketing, and verification, PAN card and voter ID can serve as valid alternatives.
