# 169
source: https://developer.mastercard.com/open-finance-us/documentation/errors/error-codes/169/index.md

User account data mismatch. An account in the return data matches multiple requested accounts. This is an issue with duplicate accounts: the end user has two accounts that appear to the software to be the same.

| **Error Message**             | An error occurred in the financial institution connection. Submitting a [support ticket](https://developer.mastercard.com/open-finance-us/documentation/support/index.md#create-a-support-case-in-scm) is the recommended action.                                                                                                                                                                                                                                                        |
| **End User Message**          | Suggest displaying the following error message to your end users - "Unexpected error has occurred. Please try again and if the problem persists contact your financial institution."                                                                                                                                                                                                                                                                                                     |
| **Common Causes**             | Connection is interrupted temporarily due to an unexpected error. It is possible that during the add account process via Connect an error occurred in the financial institution connection. For already added accounts, this means that the customer's account information has changed at the financial institution or user account data has a mismatch. This indicates an issue with duplicate accounts. The end user has two accounts that appear to be the same in the returned data. |
