Micro-deposits are two small payments that Trulia will send to your bank to verify that you've input the correct banking information and that you are the owner of that account.
It will take 1-2 days from when you manually enter your banking information for your bank to receive these payments. Zillow will send these payments directly to your bank account within that time so you'll need to check your bank statement to locate the transactions.
The payments will be two separate amounts less than $1 from ZG - Rent Payments.
After you've located both payments on your bank statement, you'll input the amounts in the verification boxes within your payment dashboard here and then click 'Verify my account'.
