Silverstreet has created a number lookup product that enables its customer to keep their databases, number validity and routing choices as accurate and up to date as possible. Silverstreet number lookup empowers our customers and simply makes Mobile Number Portability (MNP) a worry of the past.

Number Lookup

Fuss-free MNP

Silverstreet Number Lookup empowers you to keep your databases, number validity and routing choices as up-to-date as possible. It’s the most efficient way to check whether a number is disconnected, roaming or invalid and makes Mobile Number Portability (MNP) a worry of the past.

Dependable gateway

After using the Silverstreet SS7 quality Number Lookup to clean your database, start sending Bulk SMSes via our in-house developed SMSC platform, and benefit from a high end Service Level Agreement to support your traffic.

Easy payment system

We don’t charge any set up or monthly fees for our Number Lookup Service and our credits do not expire either.

Choose the right package to suit your needs

Our HLR Lookup basic package detects the mobile network code, operator name, country code, number validity, and ported numbers. Our Number Lookup advanced package also features International Mobile Subscriber Identity (IMSI) and MSC address of the phone, which is useful for identifying roaming numbers.

Reduce costs

Remember, you pay for each SMS that you send, regardless of delivery result. Sending messages to numbers that are invalid or do not exist can be very costly, particularly for enterprises that send out a large number of SMSes. Knowing which numbers are available or invalid before sending an SMS can substantially reduce costs, it is estimated by as much as 20%!
