In the Philippines, a certificate of public convenience (CPC) is required for private provision of public services for which no franchise, either municipal or legislative, is required by law, such as a common carrier.

United States
The first U.S. state statutes for certificate of public convenience (CPCN) were issued in 1870, and the U.S. Congress included a certification provision in U.S. federal law in the Transportation Act of 1920.
