Bank Bonus 101: Understanding your Chex and EWS Score

When you're churning through bank bonuses, you might eventually hit a wall where a bank denies your application. It's not usually because of your credit score (FICO), but rather due to two lesser-known consumer reporting agencies: ChexSystems and Early Warning Services (EWS).

What is ChexSystems?

ChexSystems is a consumer reporting agency that tracks your banking history. According to Doctor of Credit, 80% of banks and credit unions use ChexSystems to vet new customers.

What do they track?

Unlike credit bureaus that care about how much debt you have, ChexSystems primarily looks for negative marks, such as:

  • Involuntary account closures (the bank closed your account).
  • Bounced checks or overdrafts that were never paid back.
  • Suspected fraud activity.
  • Number of recent inquiries (how many bank accounts you've applied for recently).

Why do you care?

If you apply for too many bank accounts in a short period (a common practice for bonus hunters), you might get flagged for "too many inquiries." Some banks are "ChexSystems sensitive" and will deny you if you've opened too many accounts recently, even if your record is otherwise clean.

What is Early Warning Services (EWS)?

EWS is similar to ChexSystems but is owned by a consortium of big banks (Wells Fargo, Chase, Bank of America, etc.). It is often considered more comprehensive and harder to "game" than ChexSystems.

The Key Differences

As explained by Paycron, here is how they differ:

  1. Ownership: ChexSystems is an independent agency (owned by FIS), while EWS is bank-owned.
  2. Scope: EWS tends to have more detailed transaction-level data, especially for potential fraud or high-risk activity (like depositing a bad check), whereas ChexSystems focuses more on account closures and outstanding debts.
  3. Sensitivity: Some banks only pull Chex, some only EWS, and some pull both. Big banks explicitly favor EWS.

How to Check Your Reports

You are entitled to a free copy of your report from both agencies every year. Reviewing these reports is a crucial step before you start tracking your churn rate in PointsDB.

1. ChexSystems Report

You can request your "ChexSystems Consumer Disclosure Report" in three ways:

  • Online: Visit the ChexSystems Consumer Disclosure page. This is the fastest method; if they can verify your identity online, you may get your score immediately.
  • Phone: Call 800-428-9623. You’ll navigate an automated system to request your report by mail.
  • Mail: Download the Consumer Request for Disclosure Form, fill it out, and mail it to:

    ChexSystems, Inc. Attn: Consumer Relations 7805 Hudson Road, Suite 100 Woodbury, MN 55125

2. Early Warning Services (EWS) Report

EWS is a bit more old-school. You typically can't view it instantly online like a credit score.

  • Online: Go to the Early Warning Consumer Portal. You can start the request there, but they often require you to upload identification documents.
  • Phone: Call 1-800-325-7775 (Monday–Friday, 8am–5pm MST) to speak with a representative or use their automated system.

Pro Tip: EWS reports are incredibly detailed. They list every single deposit and transaction for accounts linked to your profile. Don't be alarmed by the length—focus on the "Status" of your accounts and any "Negative" flags.

Strategy for Bank Bonus Hunters

If you want to earn thousands in bank bonuses, you need to manage these reports carefully.

1. Know Your "Velocity" (x/6, x/12)

Just like credit cards have the "5/24" rule, bank accounts have "velocity" limits. This is usually expressed as x/6 (number of inquiries in the last 6 months) or x/12.

  • Safe Zone: 0-5 inquiries in 12 months.
  • Caution Zone: 6-10 inquiries. You might start seeing denials from sensitive banks.
  • Danger Zone: 10+ inquiries. Many banks will auto-deny you.

PointsDB users often track their "x/12" status manually or by keeping their dashboard up to date to gauge approval odds.

2. The "Freeze" Method

This is a controversial but effective strategy. You can freeze your ChexSystems and EWS reports, preventing banks from pulling them.

  • Why do it? Some banks will still approve you if they can't verify your identity via Chex, or if they have a policy to default to approval if the report is frozen (though this is becoming rarer).
  • The Risk: Many modern banks will simply deny you outright if they cannot access your report ("Unable to verify identity").
  • Best Practice: Only freeze if you are high-velocity and trying to apply for a bank known to be "inquiry sensitive" but "freeze friendly."

3. Target Sensitive Banks First

If you plan to open an account with a bank known to be sensitive to inquiries, do it before you open a bunch of smaller credit union accounts.

  • High Sensitivity: US Bank, First Tech Fed, many local Credit Unions.
  • Low Sensitivity: Chase (uses EWS primarily), Amex (uses internal data/EWS), Wells Fargo.

4. Dispute Errors

Just like with credit reports, these reports can contain errors. Common errors include:

  • Accounts listed as "Open" that you closed years ago.
  • "Fraud" flags from a simple identity verification mismatch.
  • Negative balances that were actually paid off.

If you are denied for a "negative mark" that you don't recognize, pull your report and dispute it immediately. Use the Online Dispute function on the ChexSystems website for the fastest results.


Understanding these reports is the first step to scaling your bank bonus earning strategy. By knowing your score and managing your velocity, you can avoid the dreaded "denied" letter and keep the bonuses rolling in.
