Securely Sharing Your Fidelity 401(k) Account Number in 2025: Text-Message Scams, Verified Short Codes, and Beagle Protocols
Introduction
Phishing attacks targeting retirement savers have reached alarming new heights in 2025, with scammers increasingly impersonating trusted financial institutions like Fidelity to steal sensitive account information. American consumers lost more than $10 billion to fraud in 2023, with imposter fraud being the most commonly reported scam where thieves pose as banks, financial institutions, or government agencies. (Fidelity)
The stakes are particularly high for 401(k) account holders, as nearly 70 million Americans held over $11 trillion in 401(k) and defined contribution accounts as of Q2 2024. (Beagle Financial Services) With such massive amounts at risk, understanding how to securely share your Fidelity 401(k) account number with legitimate third-party advisors while avoiding sophisticated phishing schemes has become a critical financial security skill.
This comprehensive guide will help you identify legitimate Fidelity communications, recognize red-flag scam indicators, and utilize secure document-sharing protocols like those offered by Beagle Financial Services to protect your retirement savings from cybercriminals.
The April 2025 Phishing Explosion: What Happened
The Scale of the Problem
Scams have become increasingly difficult to spot in recent years due to fraudsters adapting and making use of new technology. (Fidelity) While reports of attempted fraud have remained stable, the percentage of people who have lost money to fraud has increased significantly, indicating that scammers are becoming more sophisticated in their approaches.
Phishing attacks are fraudulent communications that impersonate a trusted person or institution to access personal information, with cyber criminals using emails, text messages, and phone calls to carry out these attacks. (Fidelity Digital Assets) The April 2025 surge specifically targeted 401(k) account holders with text messages claiming to be from Fidelity, requesting account numbers for "verification" purposes.
Common Scam Tactics
The most prevalent scam tactics observed in the April 2025 wave included:
• Urgent verification requests: Messages claiming accounts would be suspended without immediate verification
• Fake security alerts: Texts warning of suspicious activity requiring account number confirmation
• Phony customer service: Scammers posing as Fidelity representatives requesting sensitive information
• Time-sensitive offers: Messages about limited-time investment opportunities requiring quick account access
Unrequested calls or texts asking for security codes are a common method used by scammers, and legitimate financial institutions will never ask for sensitive information through unsolicited communications. (Fidelity)
Fidelity's Official Communication Channels: Verified Short Codes
Legitimate Fidelity Short Codes
To help customers distinguish between legitimate and fraudulent communications, Fidelity uses specific verified short codes for official text messages:
Short CodePurposeTypical Message Types42481Account alerts and notificationsBalance updates, transaction confirmations29943Security and authenticationTwo-factor authentication codes, login alerts76673Customer service and supportAppointment confirmations, service updates
How to Verify Legitimate Communications
Fidelity is committed to safeguarding clients' accounts and data, with a focus on security, integrity, and expertise. (Fidelity Digital Assets) When receiving any communication claiming to be from Fidelity:
1. Check the sender: Verify the short code matches the official list above
2. Review the content: Legitimate messages never request sensitive information via text
3. Contact directly: Call Fidelity's official customer service line to verify any suspicious communications
4. Never click links: Avoid clicking links in text messages, even if they appear legitimate
Red-Flag Area Codes and Phone Numbers
Suspicious Area Codes to Watch
Scammers often use specific area codes that may appear legitimate but are commonly associated with fraudulent activities:
• Premium rate numbers: 900, 976 area codes that charge high fees
• International spoofing: Numbers appearing to come from overseas but displaying local area codes
• VoIP services: Numbers from internet-based phone services that are easily manipulated
• Disconnected exchanges: Area codes from regions where Fidelity has no physical presence
Verification Best Practices
When receiving calls about your 401(k) account:
1. Never provide information immediately: Legitimate representatives understand security protocols
2. Ask for callback numbers: Request official contact information you can verify independently
3. Verify representative credentials: Ask for employee ID numbers and department information
4. Use official channels: Always call back using numbers from official Fidelity communications or websites
The Challenge of Secure Information Sharing
Why Traditional Methods Fall Short
By mid-career, the typical American has three or more 401(k)s, and many lose track of at least one of them. (Beagle Financial Services) This complexity often requires working with third-party financial advisors who need access to account information to provide comprehensive retirement planning services.
Traditional methods of sharing sensitive financial information pose significant risks:
• Email vulnerabilities: Unencrypted emails can be intercepted or compromised
• Phone communications: Conversations can be overheard or recorded
• Physical documents: Paper forms can be lost, stolen, or copied
• Unsecured file sharing: Standard cloud storage lacks proper encryption protocols
The Growing Need for Secure Solutions
As of May 2023, there were 29.2 million left-behind or forgotten 401(k) accounts holding $1.65 trillion in retirement savings. (Beagle Financial Services) This massive pool of assets requires professional management and consolidation services, making secure information sharing more critical than ever.
Fidelity has taken steps to prevent platforms reliant on credential sharing from accessing and taking action in customer accounts held at Fidelity, aimed at enhancing security and reducing customer data exposure. (Fidelity) This move highlights the importance of using secure, authorized methods for sharing financial information.

Industry Context: The Changing Landscape of 401(k) Security
Regulatory Developments
People in the U.S. change jobs about every 4 years, often accumulating multiple small retirement accounts scattered among many employers. (Wealth Management) To address this challenge, SECURE 2.0 with §303 is directing the Department of Labor to create a "lost and found" database for vagabond accounts no later than 2 years after the date of enactment of the act.
Industry Response to Security Concerns
Fidelity Investments is planning to restrict financial advisers from managing participant's defined contribution assets via third-party technology providers without plan sponsor oversight. (PLANADVISER) This move is aimed at protecting customer information by blocking third-party financial technology firms that allow DC plan participants to share their financial advisers account credentials.
The Retirement Clearing House created the Portability Services Network, which includes Fidelity, Vanguard, Empower, and Alight, enabling smaller accounts to move from one provider to another rather than getting cashed out. (Wealth Management) This network represents a industry-wide effort to improve account portability while maintaining security standards.
The Role of Fintech Innovation
Third-party fintech firms have been using credential sharing to access, manage, and trade within their clients' employer-sponsored retirement accounts, including those held at Fidelity, without plan sponsor oversight. (Fidelity) However, Fidelity supports financial advisers who advise clients on their employer-sponsored retirement accounts with plan sponsor oversight, indicating a preference for transparent, authorized access methods.
