Sources and data processing
Addresses and company details from official sources. Manual entry is always available.
Sources checked: 19.10.2026Maa- ja Ruumiamet · In-ADS
For suggestions, Zeppik sends address text to In-ADS through its server. Clicking the map or moving the marker sends coordinates to find the nearest address. Source: Maa- ja Ruumiamet open address data. Check the building number before saving.
RIK · e-Äriregister · CC BY 4.0
Details come from the local RIK Basic data directory, updated daily. If a local name search has no results, the text is sent to public RIK Autocomplete. Registration codes are searched locally. RIK licence: CC BY 4.0. Owner details and personal identification codes are not imported.
European Commission · VIES
VAT checking sends the number directly to the European Commission’s official VIES. Service failure does not mean an invalid number. The result does not verify identity, company authority or the applicable tax rate.
IBAN · MOD-97
IBAN country format and MOD-97 checksum are checked locally. The number is not sent to an external validator. This does not verify the account’s existence or owner. Bank details are never filled from a company name.
Sources and privacy
Address cache lasts up to 24 hours; VIES results up to one hour. Selected data and sources are saved with the relevant form; posted documents keep their own details snapshot. Diagnostics contain counters, timings and error codes, without search text, full addresses, VAT or IBAN.
