Here is a quiet way to lose money: take perfectly good advice — and apply it to the wrong version of reality. Indonesia replaced its business-classification system, moving from KBLI 2020 to KBLI 2025, and in doing so it renumbered, merged, split, and retired codes across the entire economy. The five-digit number a 2021 blog post hands you with total confidence may now point to nothing, or to something different from what you intend.
The codes did not just get a new coat of paint. The map was redrawn.
Four kinds of change
Working through the 2025 ground-truth, every code carries a tag for how it relates to its 2020 ancestor. Four patterns dominate:
- MATCH_LANGSUNG — direct match. The largest group: the activity and its number carried straight over. Old advice on these codes is still broadly safe (on the national side, anyway). This is the comforting majority.
- CODICE_RINUMERATO — renumbered. A few hundred activities kept their meaning but changed their number. Same business, new digits. Cite the old number and the OSS system shrugs.
- MATCH_CON_AGGREGAZIONE — merged / aggregated. Activities that were scattered across several 2020 codes got folded into a single 2025 code (or the reverse — one old code split into several new ones). The work still exists; the boundaries moved.
- BPS_ONLY — newly introduced. Activities that simply did not have a standalone code before, now created — the system getting more granular about modern sectors.
The lesson is structural: a 2025 code is not guaranteed to be the same animal as the 2020 code with the same number, and a 2020 code is not guaranteed to still exist.
The retired code: 74149
The cleanest cautionary tale in this series is a number that the expat internet still circulates with great confidence: 74149. It is handed out as "the content creator / specialised design code." Run it against the 2025 OSS ground-truth and you get nothing — It is retired. Any quote, structure, or notary instruction built on 74149 is built on a number the system has no record of.
