Validate & Optimize Your Mobile Database
Number Lookup services call upon a central database containing details of each mobile phone subscriber authorized to access the GSM network. Check validity, verify MNP status, detect roaming, and optimize your mobile number database to decrease costs and improve campaign performance.
What is Number Lookup?
Recent years have seen number lookup queries making an appearance in campaigns and programs based on mobile phone numbers. These queries allow companies to check the validity and state of mobile numbers in their databases, giving them the opportunity to optimize various processes and decrease costs by ensuring accurate, up-to-date mobile number information.
Understanding Phone Number Structure
Each phone number contains information that makes it unique from the rest of the world's phone numbers.
International Mobile Subscriber Identity
15-digit unique identifier for mobile subscribers on GSM networks
Mobile Country Code
First 3 digits identifying the subscriber's home country
Mobile Network Code
2 digits identifying the mobile network operator
Mobile Subscription ID
Last 10 digits uniquely identifying the subscriber
Complete 15-Digit Structure
In IMSIs, the first three digits represent the mobile network (MCC), the second two digits identify the country code (MNC), and the last ten digits are the MSIN - a 10-digit unique number that any carrier uses to identify a mobile phone.
How Number Lookup Works
Number Validation
Check if phone numbers in your database are valid, active, and correctly formatted for messaging campaigns.
MNP Detection
Identify when subscribers have moved to another operator but kept their old number (Mobile Number Portability).
Roaming Status
Determine whether a phone number is currently roaming to safeguard clients and prevent fraudulent activities.
