Use your origin and destination countries to structure the question, then open the HCCH Apostille Section to verify Convention status and the correct competent authority. The useful output is not just the number: it is the number together with the assumptions and eligibility checks that can change what you should do next.
What this calculator uses
The inputs on this page are Country that issued the document, Country receiving the document. The calculation uses the values you enter for Country that issued the document, Country receiving the document and returns the planning output described by the tool.
How to read the result
Do not assume an apostille is enough—or required—until the receiving authority and HCCH status/competent-authority information are checked.
What the number does not prove
A checklist helps organize evidence but does not prove a document will be accepted. Check format, validity, translation, legalisation and submission rules with the receiving authority.
Best next step
Use the output as a preparation list, then verify document format, validity, certification, translation and submission channel with the receiving institution or authority.
