Certified security and quality

Throughout Europe

GLS guarantees, checks and improves quality with a pan-European quality management system. It is certified to DIN EN ISO 9001:2015 by the internationally recognised DEKRA standards agency. With its quality management system GLS fulfils high, internationally recognised standards.

The comprehensive quality assurance of GLS includes precisely defined work processes, quality guidelines with checking routines, and regular audits. Key quality figures are continuously recorded. In this way GLS always knows precisely how many parcels arrive within the defined standard delivery times.

Seal of approval for environmental management

GLS is an environmentally-conscious company and implements sustainability projects in all its national subsidiaries. All GLS subsidiaries have obtained the ISO 14001 certification for their environmental management systems. This internationally recognised standard is considered to be one of the most important in relation to environmental management by manufacturers and service providers.


GLS is committed to equality, to education and to environmental protection. Social institutions are supported. Environmental protection is for example advanced by installing green technologies in the depots.
