How to use CPV and NAICS codes

Practical guidance for applying both classification systems in tender search and industry research.

How to use CPV codes

CPV codes are the classification system used across European Union public procurement. They help you classify procurement notices and find opportunities that match the goods, works, or services your business provides.

Choosing accurate codes makes tender alerts more relevant and helps procurement teams find suitable suppliers. Common examples include Construction (45000000-7), IT Services (72000000-5), and Medical Equipment (33100000-1).

How to use NAICS codes

Businesses use NAICS codes to describe their industries, research markets, compare economic data, and find opportunities in the public and private sectors — including registering for US federal government contracts, where a NAICS code is required as part of SAM.gov registration.

Choose the code that best matches the establishment’s main activity. Check the relevant national version too, since detailed classifications can differ by country and edition.
