HLR Lookup Service to Detect Inactive Numbers

A HLR lookup service to detect inactive numbers verifies a mobile phone number’s status by querying the home location register (HLR) via a mobile network operator. This allows a company to check if the number is valid, active in a network, and whether it is ported or roaming. It can also identify a phone’s network and carrier, allowing SMS and voice calls to be routed effectively.

HLR is the database that contains the list of a mobile phone’s current subscribers. It is accessed via the SS7 signaling network and can only be retrieved by a registered MNO. The HLR does not contain any identifiable information about the telephone user. The most common use of HLR lookup is by SMS aggregators and VoIP services to verify whether a mobile number is live and active.

This verification allows companies to avoid expensive sms messages and call charges if the mobile number is no longer active. Additionally, the aggregators can use this data to inform their marketing campaigns and plan their business strategy.

Top HLR Lookup Services for Detecting Inactive Numbers

Other businesses that benefit from HLR lookup include travel and insurance companies, market research firms, polling agencies, and even banks. For example, if a bank finds that one of its customers is using their credit card in a country or network where they have never used it before, the bank may block the transaction to protect against fraud and preserve the relationship with the customer.

An HLR lookup service can also help prevent erroneous credit card transactions by checking that the phone number is active in its system before a purchase. However, the frequency of this check depends on the needs of the company. For instance, if the business requires high levels of accuracy, then the HLR lookup should be performed more frequently to ensure that the data is accurate and up-to-date.
