What is MSISDN and how does it work?
MSISDN (Mobile Station International Subscriber Directory Number) is a unique identifier assigned to every mobile phone subscriber. It’s a combination of the mobile subscriber’s phone number and other identifying information, such as the country code and mobile network operator code. This unique identifier allows mobile network operators to identify and authenticate subscribers on their network.
MSISDN works by assigning a unique identifier to each mobile subscriber, which is then used to route calls, send texts, and provide data services. When a subscriber makes a call or sends a text, their MSISDN is sent to the mobile network operator, which then uses this information to direct the call or message to its intended recipient. This process happens seamlessly in the background, allowing subscribers to communicate with others on different networks and in different countries.
How does MSISDN differ from IMSI?
MSISDN and IMSI (International Mobile Subscriber Identity) are both unique identifiers assigned to mobile subscribers, but they serve different purposes. IMSI is a 15-digit identifier that uniquely identifies a subscriber’s SIM card, while MSISDN is a combination of the phone number and other identifying information.
While IMSI is used to authenticate the subscriber’s SIM card on the mobile network, MSISDN is used to identify the subscriber’s phone number and route calls, texts, and data services. Both identifiers are important for mobile network operators to provide services to their subscribers, but they serve different purposes in the process.
Can MSISDN be used for authentication and verification?
Yes, MSISDN can be used for authentication and verification purposes. Since MSISDN is a unique identifier linked to a specific mobile subscriber, it can be used to verify the authenticity of a subscriber’s identity. This can be particularly useful in scenarios where secure authentication is required, such as in financial transactions or online logins.
In addition, MSISDN can be used to validate a subscriber’s mobile number, ensuring that it is a legitimate and active number. This can help prevent fraud and improve the overall security of mobile-based services.
How does MSISDN impact mobile security?
MSISDN plays a critical role in mobile security as it provides a unique identifier that can be used to authenticate and verify mobile subscribers. This can help prevent fraudulent activities, such as SIM swapping and SMS phishing, which rely on fake or stolen identities.
Moreover, MSISDN can be used to implement additional security measures, such as two-factor authentication, to provide an extra layer of protection for mobile subscribers. By leveraging MSISDN, mobile network operators can improve the overall security of their networks and protect their subscribers from potential threats.
Can MSISDN be used for analytics and marketing?
