ZipLine validates your enrolled bank account information to ensure that we have the correct account number, the account is open, and most importantly that the account belongs to YOU. We do so by submitting a deposit and withdrawal to your bank account. These “challenge” transactions are a test to confirm the validity of the account. The enrolled payment card account is not activated until this bank verification process is completed. You must confirm these two amounts once they appear in your account. A “verification” email will be sent to you, upon enrollment, which explains this activation process.
