Division 99 of the UK SIC 2007 list. It holds 1 code, listed in full below with the number of active UK companies filed under each.
The official title covers extraterritorial bodies, such as international organisations. On the UK register this division is almost entirely 99999, the code recorded for a dormant company. A company showing 99999 is declaring that it is not trading. Typical examples are name-protection vehicles, companies held ready for a future venture, and old businesses wound down but not yet dissolved. The code tells you nothing about the industry a company might one day work in. It only tells you nothing is happening now.
Dormant companies usually get stripped out of a list, and for most work that is right. The code still has selective value. Accountants and filing services sell dormant accounts and confirmation statement support, because even a non-trading company faces Companies House deadlines every year. Formation agents and registered office providers renew against this population annually. The best signal is a change. When a company drops 99999 on its confirmation statement, it is announcing that trading has begun. That is one of the cleanest new-business triggers in the data.
Code 99999 marks a dormant company. It is not trading and has no significant accounting transactions. The status is self-declared through the SIC field. It is not a licence or a ruling, and Companies House does not verify it. Dormant companies still owe annual filings: a confirmation statement and dormant accounts. The code is separate from 74990, which marks a non-trading entity of a different kind.
File a confirmation statement (CS01). Replace 99999 with up to 4 SIC codes describing the new activity. There is no approval process, and the change hits the public register once the statement is accepted. Remember the accounting side too. Once you start trading, the company can no longer file dormant accounts. Speak to an accountant about the first full set.
