Inspects GSM cell phone numbers in modern and intuitive web interfaces. Generates HLR lookup reports in real time, calculates cost and sanitizes MSISDN formatting before submission.
Provides analytics with beautiful charts and meaningful data analysis. Generates reports for subscriber status, portability, roaming, extracted IMSI, MSC, MCCMNC and more.
The process of running HLR Lookups is simple. Submit MSISDNs (mobile phone numbers) via the Enterprise Web Client, the HTTP REST API, file upload, or SDKs. The HLR lookup core engine then queries the SS7 signaling network, obtains data from the relevant Mobile Network Operator (MNO) and you receive reports with results in JSON, HTML, PDF or CSV with up to 500 MSISDNs per second.
HLR Lookups is a technology to check the status of any GSM cell phone number. By making a query to the Home Location Register, the lookup service determines whether that number is valid, whether it is currently active in a mobile network, and if so which network, whether it was ported from another network, and whether it is roaming. The query will also return meta information such as the IMSI, MSC, MCC and MNC.
All mobile phone operators are connected by a network known as the Signaling System No. 7 network — or simply the SS7. The SS7 forms the backbone of the SMS (short message service) text messaging system, and it is used by cell phone operators to exchange information concerning setting up phone calls, number translation, prepaid billing systems, and so on. HLR Lookup services obtain information by sending the appropriate message over the SS7 mobile signaling network.
With the emergence of Mobile Number Portability, cell phone subscribers can now keep their number when they change carriers. One result is a dramatic rise in the number of customers who choose to change carriers and port their number to their new network, simply because they sometimes want the latest-model handset.
This of course is highly convenient for customers, but it has also created a major challenge: It is much harder now for businesses, universities, and other organizations to guarantee the successful delivery of voice calls and text messages, because their customer databases is often full of invalid or deactivated phone numbers. The result? A costly expenditure of time and money. HLR Lookup is a service that gets around this.
HLR stands for Home Location Register. It is essentially a central global database of all the cellphone subscribers registered with a particular mobile network. Every mobile operator — from Vodafone, China Mobile and Telefonica to Sprint, T-Mobile and Airtel — uses an HLR. They use it to check the authenticity of a phone call when it is registered with a transmitter, either on the person’s home network or when the person is roaming abroad.
Continually updated in real time, HLRs hold the most accurate, up-to-date information on any cell phone subscriber anywhere in the world. An HLR store details of every SIM card issued by the mobile phone operator. Each SIM has a unique identifier, called an IMSI, which is the primary key to each HLR record.
The Enterprise HLR Lookup Platform and API systems are equipped with redundant access to the global network of SMS centers and multiple geographically diverse links into the SS7 mobile signaling network. They harness the power of its high-speed technology to quickly and accurately identify large batches of mobile phone subscribers in more than 200 countries.
The platform and API support live HLR lookups, number type queries, as well as mobile number portability lookups (MNP).
Access the system via the Enterprise Web Client, our fast HLR Lookups API, or our SDKs (Software Development Kits) for PHP, Ruby, and NodeJS.

With the development of Mobile Number Portability, cell phone subscribers can now keep their number if they change mobile networks. This is great news for phone users but costly for businesses, market research companies, insurance agencies, travel agencies, universities, and other organizations that periodically call or send text messages to large numbers of people in their database. One reason: Many of those phone numbers frequently may no longer be active.
HLR Lookup is a service that gets around this. There are several ways an HLR Lookup service can save you time and money—and in a competitive market, this advantage can be critical. Here's a few of those ways.
Number type lookups determine whether given phone numbers are within landline, mobile, VoIP, premium rate or other numbering ranges and can be used to filter phone numbers that qualify for HLR lookups, SMS or voice termination. Learn more.
MNP Lookups provide a cost-effective alternative to HLR lookup queries if your primary goal is to extract the current MCCMNC of a given mobile phone number and pinpoint the original and current networks.. Learn more.
Payments are done via credit card, PayPal or wire transfer. Discounts are accrued by sending lookups or purchasing large volumes in advance. Please feel free to contact us for reseller pricing and custom discount rates to suit your budget.
