UK SIC 2007 · 99000
Activities of extraterritorial organisations and bodies (SIC code 99000)
Activities of extraterritorial organisations and bodies is UK SIC code 99000. It sits in division 99 (Activities of extraterritorial organisations and bodies) of the SIC 2007 list. On the August 2026 Companies House register, 920 active UK companies list 99000 among their SIC codes. 572 of them list it first. That makes it the second most used code in its division.
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.

SIC 99000 is a five-digit code, and the digits are not arbitrary. The first two, 99, are the division, activities of extraterritorial organisations and bodies. Add the third and you have group 990; the fourth narrows it to a class, and the fifth to the subclass, which is the level Companies House actually asks a company to pick. The whole division sits under section U, activities of extraterritorial organisations, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
More on how SIC 99000 is built
A company chooses its own codes when it incorporates and can change them on any confirmation statement. It may list up to four, and Companies House does not check whether they are right. That is why 99000 is worth reading as a claim the company made about itself rather than as a verified fact, and why the first-position and any-position counts above differ.
Measured on the August 2026 register, the busiest registered-office post towns for 99000 are London (364), Manchester (24), Birmingham (17), Swansea (14) and Leeds (9). Those are registered-office locations, which is where the paperwork sits rather than necessarily where the work happens, so treat them as where to start looking rather than as a service area.
Using SIC 99000 as a filter
920 companies is 0.02 per cent of the 5,190,464 active companies on the UK register, and ranks 99000 second most used of the 2 codes we track in division 99. That is the pool before any filter. Whether it is a big market for you depends on what you sell, but it is the number every other filter on this page cuts down from.

572 companies put 99000 first and a further 348, 38 per cent, list it in one of their other three SIC slots. That gap is the difference between a tight list and a broad one. First-code-only is the safer filter when you are writing to them; matching any position is worth it when you need the volume.
The population is concentrated: the five busiest post towns hold 47 per cent of it, and London alone accounts for 40 per cent. If you sell nationally, those five towns are most of the market. If you sell locally and you are not in one of them, expect a much smaller pool and widen the radius early.
In practice the code on its own is rarely the whole filter. Pair 99000 with an incorporation date to catch companies in their first months, when they are still choosing suppliers, or with a filing deadline to reach them while the year end is on their mind. A worked example for this code: 99000, registered office in London, incorporated in the last ninety days, which turns a 920 company pool into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a website, or a recent change of officer if you sell to whoever just took the job. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.

About SIC 99000
How many UK companies use SIC code 99000?
920 active UK companies list 99000 (Activities of extraterritorial organisations and bodies) among their registered SIC codes. Each company may register up to four. Of those, 572 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
What does SIC code 99999 mean at Companies House?
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.
How do I change my company's code from 99999 when it starts trading?
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.
