CNAM Database Limitations: Caller Name (CNAM) lookup databases are primarily national. When an international “phone number caller” places a call! The receiving country’s CNAM database typically won’t have a corresponding entry for that foreign number. This is why many international calls display only the number, or a generic “International Call” designation, rather than a name.
Regulatory Discrepancies: -spoofing laws, enforcement varies globally. A “phone number caller” spoof in a country with lax regulations might pass through a gateway and appear legitimate in a country with strict rules, before the receiving network can detect the fraud. This creates loopholes for international scammers.
Lack of Universal Identity Verification
There isn’t a single global system for verifying the authenticity of caller ID information across all international carriers. Efforts like STIR/SHAKEN are gaining traction, but their global adoption and interoperability between disparate networks are ongoing processes.
>Time Zone and Cultural Nuances: While not directly technical, managing incoming international calls also requires consideration of time zones and cultural communication preferences. A “phone number caller” from a seemingly legitimate overseas business might be calling at an inconvenient time for the recipient.
The Rise of International Scams:
The complexities of international caller ID make it a fertile ground for global scammers. They often:
Operate from Countries with Lax Enforcement: Making it difficult dataset for victims’ national law enforcement to prosecute.
>Leverage VoIP and Global Gateways: Using technologies that allow them to easily spoof numbers and route calls globally, often appearing as local calls (neighbor spoofing) to targets in other countries.
>Utilize International Premium Rate Numbers (IPRNs): Some scams involve tricking recipients into calling expensive international premium rate numbers, generating revenue for the fraudsters.
