KBS (Kimlik Bildirim Sistemi) is the system through which accommodation properties in Turkey report guest check-ins and check-outs electronically to the general law enforcement (Police and Gendarmerie), as required by Law No. 1774 on Identity Notification. Supplementary Article 1 of the law obliges properties to keep daily guest records on a computer and to report them to law enforcement instantly; the implementing regulation, amended in 2022, states that the report is made electronically by connecting to law enforcement computer terminals (no neighbourhood-headman approval is needed).
In practice there are two separate systems:
- Police KBS — General Directorate of Security (EGM); properties in municipal / police districts.
- Gendarmerie KBS — Gendarmerie General Command; properties in gendarmerie districts (mostly rural areas, villages, highland and coastal towns).
If you do not know which district your property is in: whichever force is responsible for public order where the property stands also issues your KBS account.
