Frequently Asked Questions

What's the difference between NAF and APE?

None! The APE code (Main Activity Exercised) is simply the NAF code assigned to a company by INSEE during its registration. They are identical.

How can I find an old NAF code?

Use our correspondence tool to convert between NAF versions. Enter an old code to find its current equivalent, or vice versa.

How is a NAF code assigned?

When registering a company, INSEE assigns the APE/NAF code based on the main activity declared. It can be modified if the company's main activity changes.
