The ability to validate mobile numbers and ensure they are active is no longer just a business convenience. It’s now a critical component in providing seamless customer service and increasing ROI on communication efforts. The use of global HLR lookup for validation enables businesses to quickly clean up their customer databases, curtailing the reach of invalid phone numbers and reducing costs associated with call or SMS sending to undeliverable subscribers.

Global HLR lookup validate email addresses instantly a real-time mobile network database to verify the status of any given mobile number. It determines whether the MSISDN is valid, currently active in a network, ported to another network (or roaming), and meta information such as the MCCMNC and IMSI. The process can be performed synchronously or asynchronously in real time using an API, web client or direct integration into registration, lead form capture, email marketing campaigns and other digital channels.

With the emergence of mobile number portability, it’s becoming more and more common for subscribers to change networks as they upgrade their smartphones. This can create a huge problem for companies, universities and other organizations who are trying to communicate with their customers or students using calls or SMS messages. An HLR lookup can help solve this issue by identifying which mobile operator the phone is connected to, which can then be used for more efficient routing and cost calculations for calls or messages.

At TMT ID, we provide a fast, reliable and affordable global HLR lookup service for our customers. Our system utilizes multiple redundant links into the SS7 mobile signaling network to perform HLR lookups in real time. It also sanitizes the MSISDN and calculates cost before it is submitted to the HLR, eliminating the need for complicated software or IT knowledge.
