NIB and SIUP
SIUP is no longer issued. Since licensing became risk-based, a business’s identity and its licence both start from one number: the NIB.
At a glance
- The question
- Is my old SIUP still valid, and what does the business need now?
- Short answer
- What applies now is the NIB, plus a standard certificate or a licence according to the activity’s risk level.
- Where it is checked
- OSS, where risk-based business licences are issued
- What you need
- The operator’s national ID and tax numbers, the entity’s details, the address of the activity, and the KBLI codes chosen
- What it proves
- That the listed activity may be carried out at its risk level — not that everything the company does is licensed
How to check
- Settle the KBLI code for the activity first. The risk level — low, medium-low, medium-high or high — attaches to that code, not to the size of the business.
- Register the business in OSS and obtain the NIB. It is valid for as long as the business operates; there is no annual renewal.
- At low risk the NIB is itself the licence. At medium-low, a standard certificate is added on the operator’s own declaration.
- At medium-high that certificate must first be verified by the authority. At high risk what is issued is a full licence, once the requirements have been met.
- Add whatever the activity itself attracts: environmental approval, the building certificates (PBG and SLF), and the sector permits the responsible ministry requires.
How to read the result
- A SIUP already issued is not void. Under the transitional rules it stands until it expires, but it is no longer issued or renewed in that form.
- The company registration certificate (TDP) is also gone: the Company Registration Law was repealed by the Job Creation Law, and that registration was folded into the NIB.
- The NIB belongs to a business, not to a licence. One company has one NIB, and many activities can sit under it.
- For a business that imports, the NIB also serves as its importer identification number and customs access right.
- A number printed on a letterhead or a website proves nothing. What proves it is the NIB and the licence themselves, which can be matched in OSS.
What it does not prove
- The NIB is an identity and a registration, not a statement that every requirement has been met. At medium and high risk, what decides is the standard certificate or the licence.
- The KBLI codes on it decide what may be carried out. Anything outside them is unlicensed even though the NIB exists.
- The NIB does not replace sector permits, environmental approval or building certificates.
- And it says nothing about the owner’s ability to pay or their record.
When it does not match
If there is no NIB, if the activity is not listed, or if the business details have changed, the fix is made in OSS and does not wait for an old permit to expire. A change of legal form, address or officers is filed with AHU first, because that is the data OSS reads.

A company profile here shows the registrations and licences we hold as a record, not as a certificate. A licence missing from our page means we do not hold it, not that it does not exist.

Choosing KBLI codes, reading the risk level off them and keeping the business details current in OSS is work usually handed to a consultant.
