  •   Support Reasonalbe. It will be a bit tricky to decide about formatter URL (P1630), we had a similar problem with Czech Registration ID (P4156) with some governmental organizations missing and decided to have a trade register link.--Jklamo (talk) 16:33, 26 November 2020 (UTC)
  •   Done, see BG EIK (P8894). I created this in part using a new script to simplify property creation, please let me know if something went wrong --DannyS712 (talk) 00:20, 30 November 2020 (UTC)

Try it!

  • For VAT-registered companies, EU VAT number (P3608) is the EIK prepended with the country code "BG". And the OpenCorporates ID is pretended with "bg/". Can we add that as some sort of constraint that compares two external-id fields?
