Division 47 covers selling goods to the public. One code towers over it: 47910, retail via mail order or the internet. It is the default choice for the UK's huge ecommerce and marketplace-seller population. Other non-store selling uses 47990. Physical shops register by what they stock. Convenience and food stores use 47110, clothing 47710, pharmacies 47730, florists and pet shops 47760, and dozens more specialised-store codes exist. Market and stall traders have their own run of codes, 47810 to 47890. Mixed general stores fall into 47190. The code alone tells you how a retailer trades.

Who prospects SIC 47230 companies
Few divisions get sold to this hard. Marketing and SEO agencies, payment providers, ecommerce platform resellers, fulfilment houses, courier account managers and bookkeepers all hunt retailers. The steady stream of new 47910 companies is the prize. Each one needs a storefront, payments and shipping on day one. Filing deadlines give accountants a natural opening for cleanup work. Growth between accounts hints at rising order volumes. A shop-based code plus the poor-website filter is a ready-made pitch for anyone selling ecommerce builds.
Lead generation for agency owners →How to read SIC 47230
SIC 47230 is a five-digit code, and the digits are not arbitrary. The first two, 47, are the division, retail trade, except of motor vehicles and motorcycles. Add the third and you have group 472; 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 G, wholesale and retail trade, 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 47230 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 47230 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 47230 are London (364), Grimsby (44), Birmingham (40), Dundee (26) and Manchester (24). 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 47230 as a filter
1,709 companies is 0.03 per cent of the 5,190,464 active companies on the UK register, and ranks 47230 39th most used of the 44 codes we track in division 47. 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.
More on filtering by SIC 47230
Only 966 of the 1,709 companies carrying 47230 put it first. The other 743, 43 per cent, list it behind another code, which usually means the business does more than one thing and files 47230 as a sideline. A search that matches the first code only will miss most of this population, so match on any of the four SIC positions and use a second filter to tighten it.
These companies are spread out. London is the largest single cluster at 21 per cent and the top five post towns together hold only 29 per cent, so the remaining 71 per cent sits across the rest of the country. A regional filter narrows this list without gutting it, which makes it a reasonable code to work territory by territory.
In practice the code on its own is rarely the whole filter. Pair 47230 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: 47230, registered office in London, incorporated in the last ninety days, which turns a 1,709 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.
