About UMS

UMS ASA (Unified Messaging Systems ASA) is a Norwegian technology company with international operations, headquartered in Oslo. We have more than 1,200 customers worldwide reaching over 500 million people with our systems for public notifications. The company was founded in 1998 and is established as an industry leader within the area of critical communication and population alerting systems.


UMS provide alert solutions that enable both public and private entities to communicate with customers and citizens through various channels before, during and after both unexpected and scheduled events. We use multiple technologies to leverage existing infrastructure of telecom operators when sending critical messages. Our solutions can help save lives and reduce damage to property, by providing important information for the right people, through the right channels and at the right time. The mobile phone is currently the most frequently used communication channel worldwide, and is therefore the most effective platform to inform and warn people.

As a pioneer in the development of advanced systems for critical messages, we have many unique patents known in the industry for their technological and lifesaving capabilities. We can point to more real life national systems than any other company in the world having developed national warning systems for countries including Sweden, Singapore, Netherlands, Greece, Cambodia and two coastal states in India. UMS has a strategic partnership agreement with UNISDR and has assisted countries and multilateral organisations in developing frameworks for crisis management and notification.

Being a pioneer in this area we named our services Population Alert Systems (PAS). As the market has matured the common term for this is Public Warning Systems (PWS) and this is part of the larger area of Early Warning Systems (EWS). PWS and PAS are two different names for the same type of solutions.
