DEEN
KIR (register of detainees, arrestees and probationers) is Estonia's prison/custody register — prisoners, arrestees and people under probation. Published under the Ministry of Justice, operated by RIK. The largest consumer is the Chamber of Bailiffs; Telia provides detention telephony data, hospitals exchange detainee health data. Note: not to be confused with the criminal-records register (Karistusregister).
The KIR comprises four clusters — register queries (detention/location status), custody & detainee data, a maritime/fishery strand, and service discovery. Shares are daily averages over Dec 2025 – May 2026. Each cluster has its own detail page.
The most-used service endpoints across all four clusters, as requests per day. The cluster pill links to the detail page.

How do the roughly 218,000 calls/day flow from the service clusters to the consumers?
24-hour distribution of requests to the detainee register (KIR).
What the aggregate data reveals about the detainee register (KIR).
The top consumer is KPK Täpais (the bailiff chamber's enforcement system) at 248k/day — the legal attachment pipeline runs live over X-Road.
Telia Estonia queries 21k/day of attachment/blocking data — likely for credit checks before signing contracts. An example of public-private data flow.
Zwei Services (VesselInformation, FishermanFisheryLicence) serve maritime and fishery-licence queries — unrelated to the criminal-records register, but technically attached here.
