Use GOV.UK as your starting point
Open the official verification page at gov.uk/verify-apostille and follow its link to the government service. You will need the apostille’s issue date and number. Both details are on the certificate.
Keep verification separate from document suitability
A successful certificate check does not answer every question about the underlying transaction. The recipient must still be satisfied that the document, names, format and other requirements are correct.
For an electronic apostille, retain the file
Keep the original delivered electronic document and share that file through the method agreed with the recipient. Ask for help if the file appears altered, is incomplete or cannot be opened; do not fix it by editing the signed document.
If the result is unclear
Check that the number and date have been entered accurately. Contact the issuing authority or the professional who arranged the work when you need assistance. Do not rely on a screenshot of a search result as a substitute for the certificate itself.
Common questions
Can the official UK service check paper apostilles?
Yes. GOV.UK states that its verification service covers both paper and electronic UK apostilles.
What details do I need?
The apostille number and the date it was issued, as shown on the certificate.
