    Synctera External Account Verification

    Verify account ownership, identity and account balance when funding new accounts

    Before funding a new FinTech account via an electronic ACH payment, National Automated Clearing House Association (NACHA) rules require that accounts must be validated for ownership and use prior to processing the debit transaction. Synctera External Account Verification makes it easy for FinTechs to verify external accounts and comply with NACHA rules.


    Increase conversion rates: A seamless experience embedded directly within your app’s flow makes it easy for customers to instantly verify the account

    Full visibility: Track the verification status and view the external accounts customers used for funding

    Reduce fraud: Verify account ownership and identity for all external accounts as part of the customer signup and initial funding process

    Remain compliant: Streamline NACHA compliance to ensure ongoing access to the ACH payment network

    Reduce payment errors: Prevent misdirected and failed payments by ensuring payments are set up correctly and the external account has sufficient funds

    How it works

    With Synctera External Account Verification, the verification process is streamlined, automating the sequence of steps required to remain compliant and allowing you to easily track the verification status.

    1. Validate the external account exists and can be used for ACH payments
    2. To help reduce fraud, verify that the account owner information matches the information on file for the customer (if using Synctera External Account Verification - Identity)
    3. Confirm that the external account has sufficient funds
    4. Create a record of customer information, external funding source, and proof of verification
    5. Enforce mandatory re-linking if users update password or add multi-factor authentication criteria

    Synctera External Account Verification - Identity

    Use account owner information for linked external accounts to verify customer identities

    When you allow your customers to fund their accounts with you from external sources, you will want to take steps to verify that the customer actually owns the external account, and to verify that they are not using a fraudulent identity with you. Synctera External Account Verification - Identity can help prevent fraud and reduce account takeovers by comparing account owner information for linked external accounts to the information the customer gives you. It can help reduce failed, fraudulent, or invalid ACH transfers to and from an external account. In cases where fraud does occur, the account owner information provides an audit trail.

    NACHA recommends including the external account holder name in your ACH file to help reduce returns due to incorrectly entered account numbers. In cases when an ACH is sent to an external account for which the account number was incorrectly entered, the receiving bank will be able to reduce delays in crediting or debiting the account by using the customer name to match the transaction.


    • Reduce fraud and help prevent account takeovers: identity data can be used to help prevent an account takeover (ATO) or other transaction fraud, either during onboarding or when the source of funds is switched
    • Help determine when secondary security features like text message verification should be triggered
    Example of using Synctera External Account Verification - Identity to trigger secondary security features
    If a user tries to link an external account but the identity information for that account doesn't match what the user has provided you, you can send a text message to the phone number tied to the external account, or send an email to the address tied to the external account. This helps you confirm it's really the account owner linking the account, and not someone who has stolen their credentials.
    • Use to personalize forms for onboarding: auto-fill forms with identity data when users link their bank account
    • Provide a seamless customer experience and help customers link their accounts and start transacting with you faster
