How do I link my external bank account with micro-deposits?
To link your external bank account in the app:
- Navigate to the User Profile menu on the top left corner
- Select Manager External bank account under Settings
- Search for your bank by name
- If you can’t find it, select Link with routing and account numbers
This allows you to manually link your bank to Stash using a micro-deposit verification method. This requires you to provide your routing and account numbers. Once confirmed, we’ll send 2 small amounts (micro-deposits) to your bank account to verify that you are the owner of the account and have access to it.
You’ll see these deposits in your bank account within 1-3 business days. They should appear as separate items on your bank statement.
Once you receive these micro-deposits you can link your bank:


3. Find Manage External Bank Account under Settings
4. Select Confirm Bank Account

From there, any pending transfers you set up will be processed and you’ll be able to start investing.
*If you only see one small deposit, that means that your bank is adding the deposits together. Contact your bank/credit union and ask them to tell you the two separate amounts.
Please note: When linking an external bank account, it must be a checking account. At this time, we don’t support savings accounts, third-party, or business accounts (even if your name is listed on the account).
For security purposes, micro-deposits expire after 3 failed attempts or 10 calendar days, at which point the process must be started over.
