WHAT RESULT CAN I GET BACK FROM AN HLR LOOK UP QUERY?

Depending on the country there will be one or more of the following possible types of information
returned as a result of a query.

MCC / MNC Codes

By having the MCC/MNC information, you can determine whether the subscriber has ported their
number to a different network compared with the operator prefix (also known as line range) of the
number. A Mobile Network Code (MNC) is used in combination with a Mobile Country Code (MCC) (also
known as a MCC/MNC tuple) to uniquely identify a mobile phone operator/carrier using the GSM, CDMA,
iDEN, TETRA and UMTS public land mobile networks and some satellite mobile networks. The ITU-T
Recommendation E.212 defines mobile country codes.

IMSI

Our HLR service can query the 15 digit IMSI (International Mobile Subscriber Identity number) of the
mobile subscriber's phone number (MSISDN). The IMSI is a unique number which identifies the mobile
subscribers in GSM and UMTS networks. This IMSI information is retrieved directly from the SS7
network. Querying the IMSI provides subscriber information for authentication and authorization of the
user in mobile security applications and scenarios, such as in online banking. The knowledge on IMSI
number allows also enables certain Push to Talk (PTT) services.

MSC

MSC is short for Mobile Switching Centre.

Number Invalid

This information is returned if the number is no longer active/subscribed to any mobile operator.
