Key Takeaways
According to a report, brand impersonation has risen by more than 360% since 2020. Malicious actors exploit technological advancements to carry out fraudulent activities, eroding the foundation of trust that companies work tirelessly to build. One such insidious practice is caller ID spoofing, a deceptive tactic that poses significant risks to both consumers and businesses alike.
What is Caller ID Spoofing?
Caller ID spoofing, also known as number spoofing, is the act of manipulating the caller ID information displayed on a recipient's device. Scammers employ various techniques to falsify the caller ID, making it appear as though the call originates from a familiar, trustworthy source, such as a well-known business, financial institution or government agency.
This deception aims to trick unsuspecting individuals into revealing sensitive personal or financial information, ultimately leading to identity theft or financial fraud. This usually happens with OTPs i.e. SMS verification including a lot of other business use cases too.
Here are some outcomes of Phone Number Spoofing for businesses
- Erosion of Customer Trust
- Caller ID spoofing tricks individuals into revealing personal data by posing as trusted sources.
- Even without falling for scams, customer trust in a brand is eroded, impacting its credibility.
- Reputational Damage
- Businesses linked to spoofing suffer reputational harm, requiring substantial resources to rebuild trust.
- Spoofing undermines legitimate communication efforts, as customers become more sceptical of business calls.
- Communication Challenges
- Caller ID spoofing makes customers hesitant to engage with telemarketing or service follow-ups.
- This reduces the effectiveness of important business communications, hindering outreach efforts.
- Legal and Compliance Risks
- Businesses lacking strong anti-spoofing measures may face regulatory audit and legal penalties.
- Non-compliance with data protection laws, especially in sensitive industries, leads to hefty fines.
Mechanics of Caller ID Spoofing
Here’s how Spoofing Works
- Traditional Spoofing Services
Traditional spoofing services allow users to display a false caller ID, much like prepaid calling cards. After paying upfront, users receive a personal identification number (PIN) and use it to access the service, where they input both the recipient's number and the desired spoofed ID. This method is straightforward and enables individuals to mask their true identity during phone calls and SMSs.

- VoIP Spoofing
Voice over Internet Protocol (VoIP) spoofing takes advantage of the flexibility of internet-based voice communication. Scammers use this method to easily alter the caller ID displayed to the recipient, making it appear as though the call originates from trusted sources like banks or government agencies.
This technique has become popular due to the widespread availability and ease of use of VoIP systems.
- Orange Boxing
Orange boxing is an advanced form of caller ID and Sender ID manipulation that uses software or hardware to intercept and alter the caller ID signal during a call.
Historically, it required extensive telephony knowledge and costly equipment, but modern open-source software has made it accessible to a wider audience.
This method now enables even those with minimal technical skills to manipulate caller ID information.

Recognizing Spoofed Calls
Here are ways to identify spoofed calls
- Sense of Urgency
Scammers often create a sense of urgency, claiming to represent a government agency, bank or law enforcement entity and demanding immediate action to resolve a supposed problem or face severe consequences. This tactic aims to pressure targets into making hasty decisions without verifying the caller's identity.
- Requests for Personal Information
Legitimate businesses and organizations never solicit sensitive personal information, such as social security numbers, bank account details or passwords, over unsolicited phone calls. Scammers, however, actively seek this valuable data to perpetrate identity theft and financial fraud.
- Discrepancies in Contact Information
If the caller ID displays a name or number that you recognize, but the details do not match the information stored in your contacts, it could be a sign of number spoofing. For example, an incoming call may appear to be from your bank, but the displayed number differs from the one you have on record.
- Robocalls
Automated or pre-recorded voice messages, known as robocalls, are often associated with spoofed calls. While robocalls can be legitimate in certain circumstances, scammers frequently employ them to prompt recipients to provide personal information or take specific actions.
Restoring Trust in Business Communication
- Implement Robust Caller ID Authentication
Businesses should adopt technologies like STIR/SHAKEN, which authenticate caller ID information, ensuring that calls originate from legitimate sources. This reduces the risk of spoofed calls and helps restore customer confidence in receiving communications from the business.
- Educate Customers About Spoofing Risks
Providing information on how spoofing works and how customers can identify potential scams empowers them to recognize fraudulent calls. Regular communication through newsletters, social media, and website updates can keep customers informed and vigilant.
- Enhance Customer Verification Processes
Establishing strong verification processes for customer interactions can help reduce spoofing risks like two factor authentication. Confirm the identity of callers or request additional information to ensure they are communicating with legitimate representatives.
- Create a Transparent Reporting Mechanism
Encourage customers to report suspected spoofing attempts or suspicious communications. Having a dedicated channel for reporting can help businesses track issues and respond proactively, demonstrating a commitment to customer safety.
- Maintain Open Communication Channels
Regularly update customers about the measures being taken to combat spoofing and protect their information. Open communication can reassure customers that the business is proactive in addressing security concerns, helping to rebuild trust over time.
- Utilize Multi-Factor Authentication (MFA)
Implementing MFA for sensitive transactions adds an extra layer of security, ensuring that even if a spoofed call occurs, unauthorized access is prevented. This builds customer confidence that their information is safeguarded, regardless of potential spoofing attempts.
- Monitor and Analyse Call Patterns
Businesses should actively monitor call patterns to identify any unusual activity indicative of spoofing attempts. Analysing call data can help detect potential issues early, allowing for prompt action and communication with affected customers.
- Provide Clear Communication During Calls
Train employees to introduce themselves clearly and verify customer details during calls, establishing authenticity. Clear communication helps reassure customers that they are speaking with legitimate representatives and reduces the likelihood of confusion.
- Collaborate with Telecommunication Providers
Partnering with telecom companies to implement anti-spoofing technologies and share information about ongoing threats can enhance overall security. Such collaboration can help businesses stay ahead of spoofing tactics and protect their customers more effectively.
- Offer Customer Support for Reporting and Resolution
Establish dedicated support channels for customers to report suspicious calls and seek assistance. Providing quick and effective resolutions demonstrates a commitment to customer safety, reinforcing trust in the business's integrity and responsiveness.
Conclusion
Restoring trust in business communication is vital in combating the effects of caller ID spoofing. By implementing security measures and educating customers, businesses can create a safer environment. Collaboration with telecom providers enhances protection, while prioritizing customer security strengthens brand reputation
