Standaard Bedrijfsindeling
The Dutch standard business classification, maintained by Statistics Netherlands (CBS). SBI 2025 adopts NACE Rev. 2.1 unchanged at its first four levels — all 651 classes match code and title — and adds 907 Dutch subclasses at a fifth level.

History
The SBI has followed NACE since SBI 1993, through SBI 2008 (NACE Rev. 2). SBI 2025 aligns with NACE Rev. 2.1; the first four digits are the European code and the fifth is Dutch.
Usage & importance
Used by CBS for statistics and by the Chamber of Commerce (KVK) trade register, where every Dutch business records its SBI activities. Levels 1–4 are exactly NACE Rev. 2.1, so European conversions are one-to-one.
