Shown exactly as published by the source and preserved for traceability.

EFKO code (manufacturer)iASTRA's numeric identifier for the MANUFACTURER named in position 10 (official field list: tgbasis.EFKO_H). Measured on the corpus: 4012 = BMW, 4017 = Volkswagen, 4023 = Ford-Werke, 4009 = Audi, 2076 = Peugeot — the leading digits group by country of the manufacturer's seat. 1,550 of 1,887 codes resolve to exactly one manufacturer name; the remainder reflect the free-text name and address changing over time, so the CODE is the stable manufacturer key that the name string is not. A different EFKO code (EFKO_FZ) denotes the vehicle kind — the two must not be conflated. [10 EFKO-Code]

Slash-separated position numbers, e.g. "05/09/72" or "09/30/72"; an entry may instead cite a remark line ("09/Bem.05/72"), and 4,352 approvals carry the free-text label "Entzugsdatum und Begründung" (withdrawal date and reason) in this field rather than position numbers. The date of the extension is published separately as the approval's extension date. [Erweiterung TG Positionen]
