Error In Fetch CBS Mobile Number | Steps to Fix

December 12, 2025 Freddy India 0

This Error In Fetch error message typically appears in banking applications, most commonly India Post Payments Bank (IPPB) or CSP (Customer Service Point) portals, when the system attempts to retrieve user details from the main server.

“CBS” stands for Core Banking Solution. This error means the application is trying to pull the mobile number registered with the main bank account but failed to find it or connect to the server.

Here is a breakdown of why this happens and how to fix it:

1. The Mobile Number is Not Linked

This is the most common cause. Even if the customer has an account, their mobile number might not be digitally “seeded” in the Core Banking System.

  • The Fix: The account holder must visit their home branch (or Post Office) and submit a request to update/link their mobile number to the account. Once updated in the CBS, the error should resolve.

2. Server or Connectivity Issues

Sometimes the main bank server (CBS) is down, or the link between the mobile app/CSP portal and the main server is broken.

  • The Fix: Wait for 30–60 minutes and try again. If the bank’s servers are undergoing maintenance (common on weekends or late nights), the data cannot be fetched.

3. Account Status Issues

If the account is Dormant, Frozen, or Inactive due to lack of transactions or pending KYC (Know Your Customer) documents, the system often blocks data fetching.

  • The Fix: The account holder needs to perform a transaction (deposit/withdrawal) at the branch or complete their KYC re-verification to reactivate the account.

4. Mismatch in Data

If the user is trying to link a CIP (Customer Identification Profile) to an account and the mobile number provided does not match the one in the CBS records exactly, this error may pop up.

Recommended Troubleshooting Steps

If you are a Customer:

  1. Visit the Branch: Go to your base branch (or Post Office) and ask them to check if your mobile number is correctly entered in the “CBS” system.

  2. Check Internet: Ensure your mobile data is strong; weak internet often causes “fetch” errors.

If you are an Agent/CSP:

  1. Clear Cache: Clear the cache of your banking app or browser and restart the device.

  2. Verify Account Number: Double-check that the account number entered is 100% correct.

  3. Check Logs: If other customers are facing the same issue, the bank’s server is likely down.
