In the present context, a certification is an official confirmation by a suitable person that a copy document is a true copy of the original document.

Certification through the University Administration

Please note that we only authenticate diplomas, certificates, or academic records – issued by RWTH or an institution abroad – if they are needed to apply for studies or doctoral studies at RWTH. To have these documents notarized, you must bring both the original and the required copies with you.
At the Internation Office, we charge 1.50 euros per page authenticated, and our offer is limited to a maximum of three certifications per document. Please note that we cannot certify copies of personal IDs, passports, or vital records, such as birth or marriage certificates.

The General Student’s Committee of RWTH Aachen University – AStA – offers certification services every workday from 10am to 2pm. Please note, however, that not all institutions accept documents certified by AStA.

Certification by the City of Aachen

The City Council also offers certification services. Fees for the authentication of documents however are different from those of the University Administration. For further information, please visit the respective web pages of the City Council.
