Identity theft and account takeovers are surging, with global losses from cybercrime projected to reach $15.63 trillion USD by 2029.
These fraudulent activities frequently exploit gaps in outdated or mismatched contact information to bypass security protocols. For businesses managing sensitive customer data, such oversights can lead to devastating outcomes, including hefty financial losses and regulatory fines due to non-compliance.
Yet, despite its strategic importance, re-verification of contact details when a profile is updated often takes a backseat, overshadowed by other security measures.
What is re-verification and why does it matter?
Re-verification is the process of reassessing and confirming the accuracy of information provided by existing users of any digital services. Unlike initial identity verification, which occurs at the point of onboarding, re-verification focuses on maintaining the validity of details such as phone numbers, email addresses, and other personal identifiers throughout the lifecycle of an account. This ongoing process helps businesses ensure that the accounts they manage remain secure over time.
Why are profile updates critical?
The importance of accurate contact information extends far beyond operational efficiency. When details such as email addresses or phone numbers are outdated, businesses may struggle to contact their customers promptly in critical scenarios, such as password resets or transaction verifications. Furthermore, these discrepancies create opportunities for fraudsters to exploit unmonitored accounts, potentially leading to unauthorized transactions, money laundering operations and so on.
It is of vital importance to regularly update and verify contact information, so organizations can mitigate risks and uphold compliance with evolving anti-money laundering (AML) and know-your-customer (KYC) regulations. This not only protects businesses but also fosters trust among customers who rely on the integrity of their chosen platforms.
Key components of effective user verification
User verification is no longer confined to traditional and basic methods; today, businesses are adopting a more diverse approach to ensure the accuracy and security of user accounts.
Moving beyond biometric checks
In the digital era, verifying a person’s identity increasingly relies on analyzing their digital footprint. This includes signals derived from their interactions online, such as email usage, phone number activity, IP addresses, and even browser behaviors. Digital user verification offers a unique advantage: it doesn’t require users to provide sensitive personal data like fingerprints or facial scans. Instead, businesses can cross-reference alternative data signals to establish trustworthiness. For example, a phone number that has been active for years and linked to consistent email usage may be deemed more trustworthy than a newly activated number with no associated digital history.
In this regard, digital signals become far more valuable to organizations so they can streamline user verification while minimizing intrusive practices, enhancing both security and user experience. Adopting digital signal analysis to verify users beyond the initial onboarding phase helps businesses protect against the risk of account takeover and identity theft.
Profile information update best practices
Monitoring of contact information updates is a foundational - if often overlooked - element of fraud prevention and compliance. To effectively safeguard their platforms, businesses must prioritize regular or event-based verification of customer-provided details, such as email addresses, phone numbers, and mailing addresses. These updates serve as a critical checkpoint for identifying discrepancies or unusual patterns that may signal fraudulent activity.
In addition to basic updates, advanced verification techniques can uncover valuable insights. For instance:
- Social signals: patterns of online behavior associated with a specific email or phone number can indicate whether the user is genuine or part of a coordinated fraud network.
- Connected accounts: identifying linked accounts across platforms provides a broader view of a user’s digital presence and potential risk.
- Fraud patterns: analyzing past behaviors associated with a particular contact detail, such as flagged activities or account suspensions, can highlight potential vulnerabilities.
Integrating these practices ensures that businesses remain proactive, identifying risks before they escalate into larger issues.
Why do businesses need re-verification?
While individual users and retail customers often take center stage in discussions about user verification, businesses must also undergo re-verification processes. This is particularly important for entities engaged in regulated industries like banking or payment processing. Risk-based periodic re-verification is a regulatory requirement in most countries around the world, as it ensures that the details of businesses—such as tax identification numbers, ownership structures, and operational addresses—remain accurate and up-to-date.
Business information re-verification not only helps prevent fraud but also aids in maintaining compliance with global regulations. For example, inconsistencies in a company’s listed address or sudden changes in ownership may signal potential red flags, such as shell companies or illicit activities. Regular checks help institutions verify that they are partnering with legitimate businesses and adhering to industry standards.
How risk scoring helps during profile updates
Integrated risk scoring when a user's contact details are updated provides businesses with a crucial opportunity to identify vulnerabilities that may otherwise go unnoticed.
Spotting risk signals in digital footprints
The process of updating contact information offers an opportunity to reassess potential risks associated with an account. Digital footprints, which include data such as email usage history, phone number activity, and IP addresses, often reveal trust or risk signals that are crucial for fraud prevention. For instance:
- Examples of typical trust signals: an email address consistently used across platforms, with a very limited history of data breaches, can be seen as trustworthy. Similarly, phone numbers which have been in use for a long time, have been ported from one mobile operator to another and present stable usage patterns signal reliability.
- Examples of typical risk signals: on the other hand, recently created email addresses, disposable phone numbers, or mismatched contact details can be red flags, indicating possible fraudulent intent.
These signals can be used to trigger effective controls, helping businesses address any potential threat in real time.
Mitigating risks with cross-referenced data
Cross-referencing multiple data points plays a critical role in minimizing risks during contact updates. When systems compare information like email-to-name and phone-to-name consistency, they can uncover discrepancies that may indicate fraudulent activity.
For instance, an email address associated with a completely different name across platforms could suggest that the account has been compromised. Or inconsistencies between a user's IP location and their usual login history may indicate unauthorized access attempts.
Advanced risk scoring tools can easily cross-reference multiple data points to provide a comprehensive view of a user's trustworthiness. This granular approach to verification not only improves security but also ensures that legitimate users experience minimal disruptions.
What are the key triggers for re-verification?
Re-verification is usually triggered by specific events that signal the need for a closer review of user accounts. The most typical triggers are:
1. Changes in key account information
When users update critical account details such as email addresses, phone numbers, or passwords, these changes can signal more than just routine account maintenance. While legitimate updates are common, they can also be indicators of account takeovers or unauthorized access. Having acquired the existing username and password for the account, the fraudster might change the contact details associated with it to effectively block the legitimate owner out of their own account. Regular re-verification during such changes ensures the authenticity of the new information and provides an additional layer of protection against fraud.
2. Reactivation of dormant accounts
Dormant accounts—those left unused for extended periods—often present attractive targets for fraudsters. When such accounts are reactivated, especially after prolonged inactivity, re-verification becomes essential. This process confirms the identity of the returning user and ensures that reactivation requests are legitimate, reducing the risk of fraudulent re-entry.
3. Unusual login patterns
A sudden login from an unfamiliar IP address or an unexpected geographic location can be a red flag for unauthorized account access. For example, a user who typically logs in from North America might trigger re-verification protocols if their account is accessed from a completely different region without prior notice. It’s advisable to cross-reference digital signals such as IP history and location data, so businesses can detect and address anomalies before they escalate. Therefore, using solutions like IP Address Analysis can help expose potentially fraudulent owners of existing accounts.
4. Security protocols post-data breach or fraud
In the wake of a data breach or fraud incident, re-verification serves as a critical safeguard to mitigate further damage. Reconfirming user information during these periods helps businesses identify compromised accounts, update security measures, and restore trust among users. Implementing robust re-verification protocols after such events ensures a swift and effective response to emerging threats.
