Why is my Deutsche Post tracking not updating or stuck?

A pause is usually normal. Tracked letters can travel between scans, weekends and German holidays slow updates, and international items often sit in customs (Zollabfertigung) for several days. First check you entered the full number including the closing DE with no spaces. For an export item that shows it left Germany, check the destination country's postal site for the latest scans. If a tracked item shows no movement for several working days beyond its expected window, contact Deutsche Post to open an enquiry (Nachforschungsauftrag).
