What is excluded

Natural persons (tipo de contribuyente PERSONA NATURAL, 7.7 million establishment rows) are dropped in the first pass and never written.
E.U.R.L. (sole-owner form), undivided estates and 'Y OTROS' partnerships named after people are masked as *** (968 rows).
No street address, phone or e-mail exists in the source.

Known limitations

No street address: location is province, canton and parish. No size or headcount field.
The catastro has no legal-form field; legal_form is inferred from the name (43 thousand rows stay unknown) and 29,809 rows are political-campaign accounts, flagged as such.
Mod-11 check digits are not assigned to RUCs issued after 2020; the file keeps them with tax_id_mod11_valid = false.
