Number Lookup use cases

How can you benefit from our number lookup service? Let's make sure your business doesn't waste time and money on wrong numbers.

SMS Aggregator

Are you an SMS aggregator? Wouldn’t it be ideal if you could accurately bill your users and avoid the hassle of mobile number portability complications? With the Silverstreet Number Lookup service, you can verify exactly which network the number belongs to and accurately route that message as well as accurately bill your customer for it. No more lost messages due to MNP and no more accounting discrepancies!

Financial Institutions

Financial institutions such as banks, credit card providers and others face the continued threat and concern of fraud. Silverstreet Number Lookup service can be used as a component of your authentication process by providing you with one more mechanism to verify the identity of the user to protect your customer base as well as to protect your company from liability resulting from oversights.

Marketing Campaign

Sending a marketing campaign to your registered and subscribed users or perhaps a holiday greeting to say “thank you” for their business? Silverstreet Number Lookup service can help keep costs in check by helping you identify which numbers within your database may be invalid or no longer in use. This permits you as a service provider to still make that gesture towards your users but at the same time limit, the investment size needed to achieve it.


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.

HLR lookup

Perform real time HLR lookups (Home Location Register) on our platform. HLR is a database that contains information on every subscriber of a mobile network.

Number verification

Sending SMS to non-existent, inactive and faulty mobile numbers wastes money and decreases the effectiveness of a campaign. Avoid this problem by verifying the MSISDNs you engage with.

Number portability

Porting between networks can lead to difficulties in accurate SMS routing. Through number lookup you will increase the accuracy of your routing decisions.

Campaign module

Start campaigning for singular lookups or use the bulk function to check multiple numbers at once.


Verify whether a mobile MSISDN is roaming to avoid additional costs or undelivered messages.

Made for developers

We have various code samples in our libraries to make your integration as easy and smooth as possible. Copy, paste and your service is ready to go!
