Number Portability - MNP Lookup

Provides information about the current network service provider for a given mobile number and if a number is ported out from the original number range holder. 

Over 100 countries today have implemented Mobile Number Portability (MNP). In many countries, over 40% of numbers have been ported. Therefore, knowing whether a number has been ported is a key enabler for advanced traffic routing and delivery solutions for Voice calling, SMS messaging, Rich Communication Services, Voice over LTE, Application-to-Person (A2P) messaging and the communications services of the future. ​

Key Benefits

Mitigate OBR charges

Reduce termination costs

Routing communications directly to a terminating operator rather than through intermediaries increases margins.

Service level improvements

Routing directly rather than through multiple intermediaries removes interconnection delays, avoids unnecessary business support, improves delivery assurance and leads to improved customer experience.

Global routing

Enable sophisticated routing

Advanced Routing, Rating and Revenue Assurance systems require A number and B-number portability information to implement origin and destination based routing. ​

Comparing different Number Portability providers

In the Business Messaging A2P Market, number portability has been a requirement for many years.  In most circumstances this need has been fulfilled by using HLR Lookup.  Growth in A2P SMS, the prevalence of SS7 firewall and the demand for carrier grade performance for voice and messaging applications has meant that HLR Lookup is no longer fit for purpose, although there are still some exceptions.  State of the art number portability solutions use a combination of HLR Lookup, caches, and central databases to meet the needs of leading voice and message providers.

What is unique about XConnect's Number Portability Service?

A number portability service requires global coverage, high accuracy through use of authoritative and supported data sources, flexible interfaces and commercial models, as well as carrier grade performance.

XConnect’s NPQ service provides access to global number portability information through a configurable and simple real-time query interface. NPQ uses the most authoritative data sources augmented through a managed partner network of HLR Lookup providers to maximise data quality and application suitability.
