Carrier ID
The Challenge
Phone numbers are no longer just random sequences of digits used by Communication Service Providers (CSPs) and messaging providers to route calls and SMS messages. Mobile-first apps like WhatsApp contributed to making these numbers a part of the identity of their users. This means that more and more subscribers will keep their number when switching their phone provider. Combine this with the fierce competition between CSPs, especially in markets with a very high penetration of prepaid SIM cards, and you can end up with number portability rates that can exceed 50%.
In this world, continuing to route calls and text messages by number prefix leads to unsuccessful transactions and lost money. Only those CSPs who use the most up-to-date number portability data can accurately terminate their voice calls and SMS messages, thus ensuring that they continue to properly run their low-cost routing engine.
The netnumber Global Data Services Solution
Getting access to high-quality number portability data is easier said than done. Over 90 countries have mandated the implementation of number portability, and each country comes with unique regulations, commercial agreements and technical requirements. netnumber Global Data Services began integrating these data sets into a single service more than 20 years ago, enabling fast, reliable access to number portability data across the globe.
Many data sources are stored in netnumber data centers, either close to the customers’ locations in AWS or on a customer’s premises. Our Carrier ID service delivers the fastest response times in the industry.
Given a phone number, Carrier ID will return a comprehensive set of related data elements needed to enable customers to determine various properties of the respective phone number and to map that information to their own carrier data set.
Key Features
Global Coverage
netnumber Global Data Services is the one-stop shop for number portability data, covering all 90+ countries where number portability is implemented.
Normalized Routing ID
We normalize the data in each country and return it in a common format, identifying each operator by its unique NNID.
Lightning-Fast Service
With many data sources stored in netnumber’s data centers, either close to the customer’s location in AWS or on a customer’s premises, Carrier ID delivers the fastest response times in the industry.
Global Carrier Mapping Registry (GCMR)
Carrier ID customers get free access to the Global Carrier Mapping Registry (GCMR) database. The GCMR is the world’s most widely utilized carrier identification database. The GCMR identifies every communications service provider in the world (over 200 countries) via a six-digit routing ID called an NNID. The GCMR provides the translation of the NNID into key information about the destination operator.
Authoritative Data Source in North America
netnumber Global Data Services manages the Override Service Registry (OSR). The OSR is used today by the North American messaging ecosystem to identify if an OTT/MVNO messaging service has been assigned to a given subscriber number. This ensures that SMS and MMS messages can be routed effectively to both text-enabled fixed-line numbers (OTT) and mobile numbers allocated to a virtual (MVNO) operator.
Flexible Deployment
Carrier ID can be deployed as a cloud service, in AWS or customer premises.
Customer-Defined Logic
Customers accessing Carrier ID as a query service can choose what data elements will be returned in the query response.
Fully Redundant Managed Service
netnumber Global Data Services operates a fully redundant service, which is managed and staffed 24x7. This ensures that you will receive carrier-grade service, availability and performance.
Use Cases
Least-Cost Routing
netnumber Global Data Services enables multiple CSPs, CPaaS providers and messaging hubs to route their SMS, MMS and voice traffic accurately and cost-effectively. These companies can access the data directly from the netnumber Cloud, via an AWS deployment or as an onsite service. Number portability data from over 90+ countries is complemented by global code range data, making it simple and quick to identify any mobile or landline operator globally. This feeds the routing engine and helps select the best route to use for each message and for each voice call.
Service Routing (Messaging / Voice)
Some services rely on knowing the phone number type (mobile or landline). Such an example is user registration or two-factor authentication, where the one-time password can be delivered either as text via SMS or as text-to-speech via an IVR call. Carrier ID identifies the phone number type and is therefore a useful tool for such use cases.
Fraud Prevention
Risk scoring of telephone numbers is essential for fraud prevention purposes. Different data points give useful information about the risk associated with certain actions, for example a service sign-up attempt or a financial transaction. Carrier ID helps determine the carrier associated with each telephone number. Fraud prevention algorithms can then attach a higher risk to prepaid numbers — which are typically easier to activate than postpaid numbers in many countries and therefore may be attractive to fraudsters — or phone numbers belonging to carriers which are known to have weaker security practices.
