Can’t Link Your Bank Account to a Loan Application? Here’s What to Do

A failed bank connection is almost always a technical issue, not a sign that your application was denied or that something is wrong with your account.

Here’s how bank account verification for personal loans works, why Plaid sometimes fails, and what to do next.

Why do lenders need to verify your bank account?

Lenders verify your bank account for two main reasons:

• To confirm the account belongs to you
• To confirm where loan funds may be deposited

Some lenders may also consider bank account activity, cash flow, or income consistency when reviewing an application. Bank verification is a standard part of the borrowing process that happens after your personal loan prequalification. It’s not necessarily a red flag or a sign that something is wrong with your application.

The most common verification method is an instant bank connection through a third-party service called Plaid. After your account is verified, the lender may continue reviewing the rest of your application as part of the personal loan application process.

What is Plaid and why does it keep asking for my bank login?

One of the biggest points of confusion during a loan application is seeing a separate company ask for your online banking credentials.

Plaid is a third-party financial technology service that connects bank accounts to lenders and financial apps. According to Plaid, the service connects to more than 12,000 financial institutions and is used by thousands of apps across banking, investing, and lending. When you log in to your bank during a loan application, you’re typically connecting through Plaid, not sharing your login directly with the lender.

Plaid provides read-only access, meaning it may allow the lender to verify account information but cannot move money or make changes to your account.

Thousands of financial services companies use Plaid for bank verification, budgeting tools, payment apps, and account authentication.

For example, Upstart uses Plaid for instant bank account and income verification during some applications.

Why can’t I link my bank account?

If your bank account won’t connect during a loan application, the issue is usually technical rather than financial.

Common reasons the instant bank link may fail include:

• Your bank may not currently support the connection service
• Your bank’s login system might recently have changed
• Two-factor authentication may interrupt the connection process
• There may be a temporary outage on your bank’s side or Plaid’s side
• Your login credentials may have been entered incorrectly
• Browser settings, ad blockers, or extensions may interfere with the verification window

In many cases, the issue has nothing to do with whether you qualify for a loan.

What are your options if the bank link won’t work?

If Plaid isn’t working during your loan application, you may still have several alternatives to linking your bank account.

Option 1: Try the instant link again

Before switching methods, it may help to try the connection again.

A few troubleshooting steps that sometimes resolve the issue:

• Clear your browser cookies and cache
• Try a different browser or device
• Disable ad blockers or privacy extensions temporarily
• Double-check your bank login credentials
• Wait and try again later in case of a temporary outage

If your bank still won’t connect, you may need to use a manual verification option instead.

Option 2: Upload a voided check

One of the most common alternatives to linking a bank account is uploading a voided check.

A voided check contains the information lenders need to verify your account:

• Your routing number
• Your account number
• Your name

To void a check, write “VOID” across the front of a paper check and upload a photo or scan of it during the application process.

If you don’t have paper checks, some banks may provide a direct deposit form containing the same account information.

This method is typically verified within about one business day.

Option 3: Use the small test deposits method

Another common personal loan bank verification alternative is the small deposits method.

With this option:

1. You provide your routing and account number
2. The lender sends two small deposits, usually just a few cents each
3. You log into your bank account and confirm the exact deposit amounts
4. The lender verifies the account and withdraws the test amounts

This process may take about two to three business days because the deposits need time to appear in your account.

Although slower than instant verification, it may work even if Plaid isn’t supported by your bank.

Is it safe to share my bank login with a loan application?

Borrowers may hesitate when they see a third-party service asking for banking credentials.

In general, legitimate lenders use established verification providers like Plaid because they offer a secure way to confirm bank information. When a third-party service requests access to your bank account, it’s worth checking that the connection uses HTTPS and that the service clearly explains how your data is used.

Instead of storing your actual username and password, these services typically exchange a secure authorization token after verification.

When verifying your bank account, it may help to look for:

• HTTPS in the website address
• The lender’s official domain name
• Disclosures explaining that a third-party verification provider is being used

A potential red flag is any lender requesting unrestricted account access outside of a recognized verification platform.

How does Upstart verify your bank account?

Personal loans through Upstart use Plaid for instant bank account and income verification during many applications.

If the instant connection isn’t working, borrowers may still be able to verify their account using:

• A voided check uploadCan’t Link Your Bank Account to a Loan Application
• The small test deposits method

Applicants may continue completing other parts of the application while verification is in progress instead of waiting for the process to finish first.

Upstart’s model also considers more variables than some traditional lending models when reviewing loan applications. Depending on the applicant, this may include information related to education2, employment, income, credit profile, and other application details.

Bank verification methods themselves do not affect your credit score.
