We deliver domestic parcels on the working day following the collection of the parcel. The delivery time is usually 24-48 hours for neighbouring countries and 72-120 hours for more distant countries. GLS delivers Monday through Friday during business hours. We also undertake Saturday delivery in Budapest. Delivery times are for information only. An exception to this is delivery with a time-guaranteed service (Guaranteed24Service), in which case GLS undertakes to deliver the shipment on the working day following the collection of the parcel. The service is available at an additional cost.
