The Ministry of Health and Long-Term Care Master Numbering System has been developed for the purpose of bringing together all Health Facilities and Programs under one system of identification. The list is a composite of health and health related units, facilities, clinics, programs and services. Each such organisation has been assigned a unique four digit identifying code.

This publication has been designed primarily for use by those involved in completion of the CIHI abstract. Other users should contact the Ministry of Health and Long-Term Care, Health Data Branch, Data Quality and Standards Unit, for further information concerning their use of the system.

Facilities and programs are identified by a type code, which indicates a broad service classification. Care must be taken to identify the correct service classification by type since various types of service may be provided within one facility.

Please note that due to space limitations on field lengths, some facility names have been truncated or abbreviated and do not necessarily constitute legal names.
