Spain has no single Companies House. The record is split across four official sites: a free directory, a paid registry-document service, a central registry and a daily gazette. Here is what each gives you and what you still cannot get for free.
The gazette says a company exists and what it decided. It never says a supervisor authorised it, or withdrew that. Five registers later, the identifiers were the least of what they carried — and one of them nearly filed three thousand private individuals as companies.
Nobody can tell you whether a gazette parser is complete, because there is no second copy of the truth. There is now: the registry publishes its own counts. Ours match to within half a point — after we found the mistake in our own ruler.
A Spanish NIF carries a check character computed from the eight characters before it. We ran it over all 527,318 mappings we hold. Nineteen failed — and they were 173× more concentrated in the sources that parse a tax ID out of free text than in the official registers.
