Live FAQ

Live is our real-time lookup service. We are a leading provider of mobile numbering information and data globally. The service is available via our API or through our pay-as-you-go system.

A query to the network provides up-to-date, real-time, information on whether a mobile number is active and which service provider it is currently connected to.

There are several use cases for real-time queries. If your business relies upon  customer information containing mobile numbers then you’ll know how important it is to be able to contact them. Retail businesses, call centres and sales departments may regularly want or need to contact their customers whether via a mobile telephone call or via SMS (text message). Having accurate and up to date information on whether a number is active makes your efforts more cost-effective but also compliant with GDPR and other regulatory bodies.

SMS Messaging companies sending large volumes of 2FA (Two factor authentication) messages or OTP (One Time Passcodes) also need to know that a mobile number is active as well as obtaining the correct and least cost routing for the messages they are sending on behalf of banks, e-commerce sites, airlines and ride sharing companies around the world.

Message Hubs – Sending large volumes of SMS messages to customers on behalf of banks, airlines and e-commerce sites around the world.

Marketing companies – Ensuring the mobile numbers you hold on record are still active is essential for good customer engagement and good ROI.

Contact and Call Centres – Subscribers change their number or service provide all of the time. If your customer mobile number databases are not regularly ‘cleansed’ they will contain old data. This breaks GDPR but it is also useless information for an organisation to hold, not to mention costly if you’re trying to contact inactive numbers.

E-Commerce, Insurance and Financial Services – Performing a real-time check on the number provided by a customer would validate if the mobile number provided is true and active. This enables you to engage more effectively with your customers.
