Sources and attribution
Every value here was recorded by a Korean government body. This page names them, says what each one contributes, and states plainly what this service does not do.
What we claim, and what we do not
| Government records, not estimates | Each figure is what a source recorded, as of the date shown beside it. Nothing is modelled, inferred or projected |
|---|---|
| No assessment of any company | No score, no grade, no ranking, no opinion. We state facts and where they came from. Anyone reading a judgement into these numbers is supplying it themselves |
| Companion fields say what a value is | Where a value could be read as more than it is — a generated English name, an insurance date standing in for an incorporation date — a neighbouring field says so. The fields that carry this |

Corrections
If a record is wrong, write to support@notonlystock.com with the registration number and what you believe the correct value is. Where the source says otherwise, we correct it and say when. Where the source itself is wrong, we cannot overrule it — but we will tell you which body holds the record so you can have it changed at the origin, and the correction will reach us on the next refresh.
Attribution
These records are Korean public data, collected and republished here under the terms each source publishes them with. Using this API does not require you to credit us or them, but this page is here so that anyone who wants to trace a figure back can.
