Abstract: Methods and systems for providing real-time external account validation during the opening of a new financial account include receiving external account information and validation information for use in validating that an account owner corresponding to the new financial account is associated with an external financial account provided by an external institution. The received information may be electronically transmitted to the external institution, and the external institution may respond with an electronic indication of an affirmative validation. Upon reception of the affirmative validation, an electronic funds transfer from the external account to new financial account may be initiated. The real-time external account validation may be performed in real-time, e.g., during a single business day or during a single session established with a computer of the institution providing the new financial account.
