A. Each Competent Authority is required to keep a register in which it records the date and number of every Apostille it issues, as well as information relating to the person or authority that signed or sealed the underlying public document. Recipients may contact the Competent Authority identified on the Apostille and ask whether the information on the Apostille corresponds with the information in the register. In order to verify a particular Apostille, recepients may contact the Competent Authority. Contact information for the Competent Authorities, including phone numbers and website information, such as the URL of e-Registers where applicable, is available in the Apostille Section of the Hague Conference website: Many Competent Authorities have started to operate online electronic Registers (e-Registers). These e-Registers allow for easy online queries to verify the origin of an Apostille without Competent Authorities having to answer these queries individually by phone, e-mail or otherwise. If a Competent Authority operates such an e-Register, the web address of the e-Register is mentioned on the Apostille. While the Permanent Bureau (Secretariat) of the Hague Conference provides a broad range of services to support Contracting States in the effective implementation and practical operation of the Apostille Convention, it does not issue any Apostilles, does not maintain any register of Apostilles and does not keep any copies of Apostilles. If the intended recipient of your apostillised public document has doubts about the origin of the Apostille, you should encourage him or her to immediately contact the Competent Authority mentioned on the Apostille and ask the latter to verify whether it really issued the Apostille. If available, an e-Register allows for a quick online query. – This text was extracted from “The ABC of Apostilles” by the HccH (Hague Conference on Private International Law that you can look at:
