How do you read a code for retail trade in ISIC Rev. 5?

Reading a code for retail trade in ISIC Rev. 5, published by the UN Statistics Division, starts with Section G for trade, then narrows to retail rather than wholesale, then to the store type and the goods family, and finally to the specific retail activity. Each level answers a narrower question: trade or not, retail or wholesale, specialised or non specialised, which goods, and which precise activity. A longer code is therefore a more precise description, not a higher rank or a better shop. This guide explains reading logic only and does not assign a code to any reader or shop.

What question does each level of the code answer?

Reading a retail code in ISIC Rev. 5, published by the UN Statistics Division, works like answering a short chain of questions in order. The first question is whether the activity is trade at all, which points to Section G. The second question is whether the trade is retail rather than wholesale, which narrows the field to selling to the general public for personal or household use. The third question asks about store type: specialised or non specialised. The fourth asks which goods family is involved. The fifth asks which precise retail activity is described. Each answer narrows the previous one, so a longer code is a more precise description, not a higher rank and not a better shop. A short code that stops early is simply less specific, and a long code that goes further is simply more detailed.

That chain also explains why guessing from the section letter alone fails. Section G covers a wide field, from wholesale to retail and from shops to non store channels, so two businesses inside it can differ sharply once the later questions are asked.

Why can an online seller and a high street shop share a class?

Channel alone does not always create a separate class in ISIC Rev. 5, published by the UN Statistics Division. An online seller and a high street shop can share a retail class if they sell the same goods to the same kind of buyer, because goods and buyer carry more weight than the route the goods took. A website, a counter, and a catalogue can all be routes for the same retail activity when goods and buyer match.

The reverse is equally important. Two shops on the same street can sit in different classes if one specialises in food and the other sells a general range. Same street, same opening hours, same kind of till, yet different descriptions, because the store type and the goods family differ. Street address tells a reader where a shop stands. It does not tell a reader what the shop sells or how broad its range is, and those are the details the later levels of the code capture.

How does the clothing shop example work, step by step?

Suppose a register lists a clothing shop under a Section G code. Reading it means starting at the section and confirming trade, then moving to the retail division and confirming selling to the general public, then asking whether the group describes specialised retail, and then asking whether the class matches clothing. Each step needs its own check. If the group described a general range instead of a specialised one, the reading would falter at that step, even if the section and the division looked right. If the class matched a different goods family, the reading would falter at the last step, even if every earlier step looked right.

If any level does not match the shop’s range, the code should be queried with the holder of the record, because registers are maintained by offices that hold fuller information about the unit than a short guide can see.

What sits below the international class, and what sits around it?

ISIC Rev. 5, published by the UN Statistics Division, is a hierarchy from broad sections to narrow classes: section for the broad field, division narrowing it, group narrowing it further, class for a specific kind of activity. National versions may add detail below the class, so a national code can look longer than the international code for the same activity. That extra detail adds local precision without changing the international reading, and readers comparing codes across countries should compare at the international level first.

Boundaries here are lines drawn for measurement, not walls between real businesses. A firm doing several kinds of work at once is simply performing more than one described activity, and its record needs to reflect that fuller picture through the office that holds it.

On reading a code for retail trade, the code statements here follow the UN Statistics Division classification detail and the ISIC Rev. 5 publication in the frontmatter.

Treat this guide as reading help for a statistical system, nothing more. It does not assign you a code, name your principal activity, or complete your registration, and the national statistical institute or business register that holds your record is the authority to confirm those points.
