Why is UPI ID not getting activated?

UPI has made digital payments seamless, but sometimes there could be issues that users can face where their UPI ID not getting activated or verification fails. It can be related to connectivity or credentials mismatch or any other technical reason for that matter. 
 
Let’s understand why this happens and how to fix it quickly in more detail. 

Common Reasons for UPI Activation Failure 

If your UPI ID not getting activated, it usually comes down to verification or system-level issues. Here are the most common reasons: 

1. Mobile Number Mismatch 

UPI works only if your mobile number matches the one linked to your bank account. Even a slight mismatch leads to UPI activation failed errors. 

2. SMS Verification Failure 

UPI apps send an SMS for verification. If: 

• SMS permissions are disabled 

• SIM has no balance 

• Wrong SIM slot is used 

…your UPI ID not activated issue can occur. 

3. Poor Network Connectivity 

Weak internet or mobile network can interrupt communication between your bank and the app, causing repeated UPI activation failed attempts. 

4. Bank Server Downtime 

Sometimes, the issue isn’t on your end. Bank servers may be under maintenance or heavy load, leading to temporary failures. 

5. Outdated UPI App 

Using an outdated app can cause compatibility issues with updated NPCI guidelines, resulting in your UPI ID not getting activated properly. 

6. Device Verification Issues 

UPI allows only one device per account. Switching phones frequently can lead to device registration errors. 

7. Inactive or Restricted Bank Account 

Dormant accounts, incomplete KYC, or frozen accounts cannot be linked to UPI, leading to UPI ID not activated problems. 

8. Incorrect Date & Time Settings 

UPI systems rely on secure timestamps. Incorrect device time can silently cause activation failures. 

9. System Outages 

Even large-scale outages can affect UPI services like the 2025 disruption that impacted multiple banks and apps across India. 

Things to Be Careful of When Activating UPI ID 

Avoid these common mistakes while setting up UPI: 

1. Registered Mobile Number: Ensure your bank-linked number is active and inserted in the primary SIM slot. 

2. SMS Services Active: You need an active SMS plan for verification. 

3. Stable Internet: Switch to a strong mobile data or Wi-Fi network during setup. 

4. Update Your UPI App: Always use the latest version to avoid bugs and compliance issues. 

5. Check Bank Account Status: Ensure your account is active and KYC is complete. 

6. Avoid Multiple Attempts: Too many failed attempts can temporarily block activation for security reasons.

2. Reinsert SIM Card: Ensure the correct SIM is in slot 1 and active. 

3. Enable Permissions: Allow SMS, phone, and network permissions for the app. 

4. Update the App: Download the latest version from Play Store/App Store. 

5. Check Mobile Number with Bank: Visit your bank or net banking to confirm your registered number. 

6. Wait & Retry Later: If servers are down, retry after a few hours. 

7. Contact Bank or NPCI Support: If the issue persists, raise a complaint via official support channels.  

8. Switch Network: Sometimes switching from Wi-Fi to mobile data (or vice versa) resolves issues.
