According to https://docs.microsoft.com/en-us/azure/best-practices-availability-paired-regions there is a Regional-Pair to „Germany West Central“ called „Germany North“ which is missing at https://azure.microsoft.com/en-us/global-infrastructure/geographies since access is restricted to support specific customer scenarios, for example in-country disaster recovery. These regions are available only upon request by creating a new support request in the Azure portal
Germany North could be found in the list (https://azure.microsoft.com/en-us/global-infrastructure/geographies/#new-regions) so it might be coming soon for general availability.
