Participation in the UN Global Compact (UNGC) is open to any company that is serious about its commitment to work towards implementation of the UNGC principles throughout its operations and sphere of influence, and to communicate on its progress. Properly constituted (under prevailing national law) companies from any industry sector are eligible for participation, except those companies involved in the manufacture, sale etc. of anti-personnel landmines or cluster bombs, companies that are the subject of a UN sanction or that have been blacklisted by UN Procurement for ethical reasons. Remaining in good standing requires communicating the company's progress in implementing the principles, respecting the Policy on the Use of the Global Compact Name and Logos, and a willingness to engage in dialogue under the integrity measures in the event that a matter is raised under those procedures.

Businesses with fewer than ten employees (micro-enterprises) will be able to apply for membership likewise all other businesses, but it is expected a longer timeline for reviewing the application and it may involve the Local Network.
