If you've added a Chase bank account to Innago through Instant Verification, you may have noticed that the last four digits of the account number appear to differ from your actual Chase bank account number. This is because Chase actually sends us what's known as a "Tokenized Account Number" that's attached to your bank account. We understand how this could be confusing, but we can assure you that you have successfully linked the correct account.
Here is a statement on the TAN directly from Chase's website:
"The Tokenized Account Number (TAN), is a secure method for our partners to share an account number that can be used for Automated Clearing House (ACH) or Real-time Transport Protocol (RTP) transactions that isn't the actual account number. Using a TAN reduces the risk of a customer's account number being compromised."
If you still have concerns, you can visit Chase's website where they provide more information here.
