Guide: What to Do Immediately After Discovering Fraudulent Activity

Discovering that your identity has been stolen can be overwhelming. In an instant, your financial health, personal security, and credit reputation feel threatened. For individuals working to improve or maintain their Middle Credit Score®, the stakes are even higher. Every fraudulent charge, new account, or missed payment tied to identity theft can negatively impact your score and delay your financial goals for months or even years.

What makes identity theft especially dangerous is that it often goes unnoticed until the damage has already occurred. Maybe you’re applying for a mortgage and see an unexpected dip in your Middle Credit Score®. Perhaps you receive a bill in the mail for a loan you never took out, or worse, a debt collector contacts you about a delinquent account you’ve never heard of. However it surfaces, your response must be immediate and strategic.

This guide is written to provide a comprehensive and action-focused framework for what to do the moment you confirm—or strongly suspect—that your identity has been compromised. From securing your accounts and initiating fraud alerts to filing reports and beginning the credit recovery process, each step you take in the first 24–72 hours can dramatically influence your ability to limit the fallout and protect your Middle Credit Score®.

Identity theft can feel paralyzing, but with a clear plan and a calm, decisive approach, you can regain control. We’ll not only cover what to do—we’ll explain why it matters, how long each action takes, and how to keep your recovery organized and legally documented every step of the way. Whether you’ve been targeted by a cybercriminal, a thief stole your wallet, or your information was compromised in a data breach, the response plan in this guide is your best defense.

For consumers focused on their Middle Credit Score®, special attention will be given to how fraud can impact one bureau more than the others, how to track score changes, and when to request score recalculations from lenders after the issue has been resolved. This isn’t just about damage control. It’s about reclaiming your financial confidence.

Before you panic, let’s take a breath and start step-by-step. This 2000-word guide will walk you through everything you need to do to stop the fraud, minimize long-term impact, and protect your credit standing as quickly and thoroughly as possible.

Step 1: Secure Your Accounts Immediately

The moment you detect fraud, your top priority is to prevent further unauthorized access. Start by changing the passwords for all financial, email, and mobile accounts. If possible, enable two-factor authentication for added security.

Key actions:

• Change passwords for all bank accounts, credit card portals, and investment platforms.
• Use strong, unique passwords that mix letters, numbers, and symbols.
• Enable two-factor authentication where available.
• Log out of all sessions across devices for compromised accounts.

Contact your bank and credit card issuers to report any unauthorized activity. Ask them to:

• Freeze or close the affected accounts.
• Reissue cards with new account numbers.
• Begin internal fraud investigations.

Timeframe: Within the first 1–2 hours of discovering fraud.

Step 2: Place a Fraud Alert or Freeze on Your Credit

Next, place a fraud alert on your credit file. This makes it harder for someone to open new accounts in your name. Fraud alerts are free and last for one year, and placing it with one bureau (Equifax, Experian, or TransUnion) automatically notifies the other two.

Alternatively, you can place a credit freeze on your reports, which completely restricts access to your credit file.

What to do:

• Visit one of the credit bureau websites to place the alert (start with Equifax, TransUnion, or Experian).
• If opting for a credit freeze, initiate it with all three bureaus individually.

Timeframe: Within the first 6–12 hours.

Step 3: Review All Three Credit Reports Thoroughly

Once your file is protected, it’s time to assess the damage. Pull your credit reports from AnnualCreditReport.com. Look for unfamiliar accounts, incorrect addresses, or hard inquiries you don’t recognize.

Create a spreadsheet to track every suspicious item. Be sure to:

• Note the bureau reporting the issue.
• Document the creditor or institution involved.
• Mark the date the account was opened or changed.

Timeframe: Within 12–24 hours.

Step 4: File an Identity Theft Report with the FTC

The Federal Trade Commission (FTC) offers a simple online process to document your identity theft case and generate a formal recovery plan.

Visit IdentityTheft.gov and follow the steps to:

• File your identity theft affidavit.
• Generate pre-filled dispute letters and reports.
• Receive personalized recovery steps.

This document is your official report when working with credit bureaus and creditors.

Timeframe: Within 24 hours.

Step 5: File a Police Report (Optional but Recommended)

Although not always required, a police report adds legal authority to your identity theft case. This can help strengthen your disputes and is required by some financial institutions.

Bring the following when visiting your local police station:

• FTC Identity Theft Report
• Government-issued photo ID
• Proof of address (e.g., utility bill)
• Documentation of fraudulent charges

Request a copy of the report and record the report number.

Timeframe: Within 24–48 hours.

Step 6: Begin Disputing Fraudulent Accounts

Using your FTC report and police file, send dispute letters to each credit bureau reporting an error. Include copies of all supporting documentation.

The bureaus must investigate your claim within 30 days. They will:

• Contact the creditor
• Review your evidence
• Notify you of the results

If successful, the account will be removed from your report.

Timeframe: Begin within 48 hours of discovery.

Step 7: Notify Creditors and Lenders Directly

If the fraudulent accounts are tied to specific banks or credit card companies, notify them directly. Send letters via certified mail with return receipt requested.

Ask them to:

• Close or block fraudulent accounts
• Remove fraudulent charges
• Provide documentation verifying removal

Keep records of all phone calls and written communications.

Timeframe: Within the first 3 days.

Step 8: Monitor Your Middle Credit Score® Closely

Once disputes are underway, it’s important to track your Middle Credit Score® weekly. Because identity theft often affects only one bureau, your middle score (the median of all three) can fluctuate unevenly.

Tips:

• Use a tri-bureau credit monitoring tool.
• Create a credit score log.
• Watch for changes in utilization and account status.

Request a lender re-pull if your score improves significantly after fraudulent accounts are removed—especially during a mortgage or loan application.

Timeframe: Ongoing—check weekly.

Step 9: Create an Identity Recovery Binder

Organize your identity theft recovery in a physical or digital binder. This will help if you need to escalate disputes or re-file documents.

Include:

• Credit report printouts
• FTC and police reports
• Dispute letters and responses
• Bank correspondence
• A timeline of events and actions taken

A clear record demonstrates your diligence and can expedite resolutions.

Step 10: Rebuild Confidence and Reassess Credit Tools

After the immediate danger has passed, use this experience to strengthen your credit security going forward.

Action items:

• Consider credit monitoring services with fraud insurance.
• Sign up for account activity alerts.
• Enroll in identity theft protection programs.
• Audit passwords and security questions across all accounts.

Reflect on what information may have been compromised and change behavior patterns (e.g., avoid public Wi-Fi for financial tasks, reduce social media sharing).

Final Word: Rapid Response Protects Your Middle Credit Score®

Fraudulent activity doesn’t have to destroy your financial progress. By responding quickly, documenting thoroughly, and communicating assertively, you can limit the damage and protect your Middle Credit Score®.

Every hour counts. The first 72 hours after discovering identity theft are the most critical. This guide gives you the roadmap you need—now it’s time to follow it.
