How do I connect my financial institution to an app using Plaid micro-deposits?

Some apps use Plaid to help you safely connect your bank account. One way Plaid can do this is by sending a tiny test deposit—called a micro-deposit—to your bank. Here's how the process works, step by step.

 

What Is a Micro-Deposit?

A micro-deposit is a small amount of money (usually $0.01) that Plaid sends to your bank account to make sure everything is set up correctly. This deposit includes a 3-letter code you’ll use to finish linking your account.

 

Link Your Account with Micro-Deposits

  1. Start the connection process in your app
    • When you search for your bank, choose Link with account numbers (if the app offers this option).
  2. Enter your bank details
    • Type in your routing number and account number.
    • Double confirm that the numbers are correct. 
  3. Wait for the micro-deposit
    • Plaid will send a $0.01 deposit to your bank account. This usually takes 1–2 business days.
    • In some cases, Plaid can verify your info right away. If that happens, you're all set.

 

How to Find and Use Your 3-Letter Code

 

 

If your app asks for a 3-letter code, follow these steps:

  1. Log in to your bank’s app or website
  2. Look for the $0.01 deposit
    • This is the test deposit Plaid sent.

  3. Tap or click on the deposit to see the full details
    • You should see something like this:

  1. Find the 3-letter code
    • In this example, the code is ABC

  2. Go back to your app and enter the code
    • This confirms your bank account is linked.

Having Trouble?

  • Didn’t get the $0.01 deposit? Contact the app or service you’re trying to connect to—they can check the status for you.
  • Typed the wrong account number? Start over and enter the correct routing and account numbers.
  • Other connection issues? Again, reach out to the app. They’ll be able to look into your connection and help you out.
