How to find your NMA code
Start with the activity that really generates revenue, then compare nearby NMA codes before registration.
Quick method
- Describe the main activity and source of revenue.
- Identify the closest NMA section.
- Compare nearby branches and detailed codes.
- Review licences, tax and CNSS implications before registration.
Useful portals to keep in mind
| Portal | Why it matters | Reference |
|---|---|---|
| HCP | Official NMA nomenclature | HCP |
| DirectEntreprise | Company creation path | DirectEntreprise |
| SGG | Regulated activities | SGG |
A common classification mistake
Many users pick a code because the title sounds close to their marketing description. A stronger method is to start from the product or service that actually generates revenue, then test whether it is the core activity, a support activity or a mixed business model.
When to open other pages at the same time
Open VAT, CNSS and licensing pages as soon as the code choice affects price, payroll, public-facing operations or a possible authorisation. The right code is not an isolated target; it improves the reliability of the whole business setup.
Practical checklist before acting
- Identify the real activity, product or service that generates revenue.
- Match it with the NMA code, tax treatment, CNSS implications and possible licence path.
- Prepare official documents and verify the current procedure before filing anything binding.
