1. Credit Note
A credit note (C/N or cn) is a document issued by a seller to a buyer when goods are returned. It allows the buyer to deduct the returned goods' value from future purchases. This is a common abbreviation used in accounting and business transactions.
2. Combined Nomenclature
Combined Nomenclature (CN) is a standardized system used to classify goods for international trade. It's essential for determining tariffs and other trade regulations. This is primarily used in international commerce and customs.
3. Canadian National Railway

4. Certificate of Need (various contexts)
In the healthcare sector, CN often refers to a Certificate of Need. Several state governments use CN application forms (e.g., New Jersey's CN-1, CN-3 forms—see links provided in the references). These forms are used to apply for approvals for various healthcare projects and services. The exact meaning and application process differ based on the governing body.
5. Copernicium
In chemistry, Cn is the chemical symbol for copernicium, a synthetic chemical element. This is a highly specific scientific abbreviation.
The specific full form of CN depends entirely on the context in which it's used. Always consider the surrounding information to determine the correct interpretation.
