If you have used your Chase Bank account to connect to Truss, you might notice that your account numbers look different when you log into the platform, but that is no cause for concern.

Chase Bank uses "substitute account numbers" when providing authorized third parties with sensitive financial information. This measure is done to help protect Chase users from fraud and other potential security issues. The given "substitute numbers" are only relevant for transactions placed within the third-party platform.

When you connected your Chase account to the Truss platform, Plaid acted as a "Data Access Provider". During the account connection process, Chase Bank provided Plaid with protective "substitute account numbers" for your Chase bank account, which were then passed to Truss. The "substitute account numbers" serve the same purpose as your actual Chase Bank account numbers in the Truss dashboard.
