United Nations Office for the Coordination of Humanitarian Affairs
The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) is a United Nations (UN) body established in December 1991 by the General Assembly to strengthen the international response to complex emergencies and natural disasters. It is the successor to the Office of the United Nations Disaster Relief Coordinator (UNDRO).

The Department of Humanitarian Affairs (DHA) was established shortly thereafter by the Secretary-General, but in 1998 was merged into OCHA, which became the UN's main focal point on major disasters. OCHA's mandate was subsequently broadened to include coordinating humanitarian response, policy development and humanitarian advocacy. Its activities include organizing and monitoring humanitarian funding, advocacy, policy-making, and information exchange to facilitate rapid-response teams for emergency relief.

OCHA is led by the Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator (USG/ERC), appointed for a five-year term. Since July 2021, the role has been filled by Martin Griffiths of the United Kingdom.

OCHA organized the 2016 World Humanitarian Summit in Istanbul, Turkey. It is a sitting observer in the United Nations Development Group.

Services
OCHA has built up a range of services in the execution of its mandate. Some of the larger ones are:
IRIN, Integrated Regional Information Networks, a humanitarian news and analysis service (1995–2014) Since 1 January 2015, IRIN now operates as an independent news service, The New Humanitarian, and is no longer affiliated with OCHA.
INSARAG, International Search and Rescue Advisory Group
ReliefWeb, a leading source of time-critical humanitarian information on global crises and disasters. ReliefWeb is a 24/7 service that provides the latest reports, maps, infographics, and videos from trusted sources, as well as jobs and training programs for humanitarians. (1996)
Central Emergency Response Fund, a humanitarian fund established by the UN General Assembly to 1) promote early action and response to reduce loss of life; 2) enhance response to time-critical requirements; and 3) strengthen core elements of humanitarian response in underfunded crises (2006)
Humanitarian Reform seeks to improve the effectiveness of humanitarian response by ensuring greater predictability, accountability and partnership.
Who does What Where Database and Contact Management Directory: To ensure that appropriate and timely humanitarian response is delivered during a disaster or emergency, information must be managed efficiently. The key information that is important to assess and ensure that humanitarian needs are met in any emergency/disaster are, to know which organizations (Who) are carrying out what activities (What) in which locations (Where) which is also universally referred to as the 3W (Who does What Where). The integrated Contact Management Directory, complements the 3W database, making it easy for the user to navigate through the application.(2006)
Common and Fundamental Operational Datasets (CODs) are critical datasets that are used to support the work of humanitarian actors across multiple sectors. They are considered a de facto standard for the humanitarian community and should represent the best-available datasets for each theme.  The Fundamental Operational Datasets (FODs) are datasets that are relevant to a humanitarian operation, but are more specific to a particular sector or otherwise do not fit into one of the seven COD themes. The main source of curated CODs is accessible via the Humanitarian Data Exchange, though CODs may also be found on various governmental and independent websites.
Since 2004, OCHA has partnered with the Center for Excellence in Disaster Management and Humanitarian Assistance to facilitate OCHA's Civil Military Coordination (UN-CMCoord) course in the Asia-Pacific Region. The UN-CMCoord Course is designed to address the need for coordination between international civilian humanitarian actors, especially UN humanitarian agencies, and international military forces in an international humanitarian emergency. This established UN training plays a critical role in building capacity to facilitate effective coordination in the field by bringing together approximately 30 practitioners from the spectrum of actors sharing operational space during a humanitarian crisis and training them on UN coordination mechanisms and internationally recognized guidelines for civil military coordination.
Office for the Coordination of Humanitarian Affairs occupied Palestinian territory (OCHAoPt). OCHA's Country Office in the occupied Palestinian territory (oPt), established in 2002 to support international efforts to respond to the deteriorating humanitarian situation in the oPt.
Since 2015, the annual production of the Global Humanitarian Overview reports.
Since 2015, OCHA acts as the secretariat for the Humanitarian Networks and Partnerships Weeks.

Humanitarian innovation in organizations

The OCHA encourages humanitarian innovation within organizations. For organizations, it is a way of identifying and solving problems while changing business models to adapt to new opportunities. In OCHA's occasional policy paper Humanitarian Innovation: The State of the Art, they list the reasons why organizations are moving toward providing their own kind of humanitarian service through innovation: 
Shifting business models based on public demand: There is a growing amount of humanitarian emergencies and the old model of response does not fit the modern problem.  
Increased contributions from the private sector: Private organizations are driven by their obligation to Corporate Social Responsibility and now associate their contributions to their brand.
Developing partnerships within organizations: Partnerships lead to new ideas and solutions to problems.
Trend toward developing innovative technologies: Technology allows people to respond to emergencies quicker.

They also list potential challenges associated with these changes:
Humanitarian innovation requires a different market structure: It is assumed that there is no incentive for private organizations to participate in humanitarian innovation. 
Inequalities in power can stimulate conflict: There is no general principle for ethics in innovation. If humanitarian innovation is carried out incorrectly, there can be consequences to communities, individuals, or the system at large.
Monetary and political risk if humanitarian efforts fail: This risk can cause delayed responses to humanitarian issues, so organizations tend to look to the past rather than plan for the future.

International dialing code
The OCHA was assigned its own international calling code +888. Telephone numbers in the +888 "country code" were assigned to agencies providing humanitarian relief. The +888 code was implemented by Voxbone. However, the assignment of the +888 code has been withdrawn.
