A United States Passport

If you want official United States documents to be recognized in a foreign country, such as birth certificates, university transcripts, professional licenses, income verification, trademarks, powers of attorney, affidavits, etc., then that documented will need to be Authenticated. Depending on the country of destination, either an Apostille or Authentication Certificate will be required; both are considered "authentications".  


Apostilles are used when public documents are being transferred between countries that are party to the Hague Apostille Convention of 1961. This international treaty streamlined the cumbersome, traditional procedure for authenticating documents. The apostille is issued by the California Secretary of State’s office. The single apostille is the only certification needed. Once prepared and verified, the apostille is attached to and sent along with the notarized documents.


Authentication certificates are used for destination nations that are not part of the Hague Convention. Instead of a single apostille, the document needs several authentication certificates, including those from the California Secretary of State, the U.S. Department of State, the consul of the destination country and potentially another government official in the destination country.

Standard processing time for apostilles services can take up to 8 business days. However, apostilles may be expedited to 1-2 business days. 


Authentication certificates are much harder to predict as there are a number of officials involved in the authentication process. However, the chances are that your destination country participates in the Hague Apostille Convention of 1961. If not, never to worry, GoStamp! is here to help you through the process in whatever way possible.
