COA provides Hague accredited and approved adoption service providers with a Hague Convention accreditation or approval certificate for display, as well as copies of a certification mark for use on adoption service provider stationery, while accredited or approved by COA. Only Hague Accredited and Approved providers are authorized to use the certification mark.  Applicants seeking accreditation or approval are not authorized to use the certification mark.

If an accredited or approved adoption service provider becomes unaccredited or unapproved, it must not represent itself as an accredited or approved provider during the applicable period. Specifically, the adoption service provider must discontinue using any documentation that states or implies that it is Hague accredited or approved, including the use of stationery with the certification mark and the display of a Hague Convention certificate.
