NHIS coordinates checks on documents issued abroad
On 13 October 2026, the National Health Insurance Service (NHIS) announced a system for recording document-verification histories and sharing them across its branches. The announcement gives 14 October 2026 as the start of operation. This concerns checks on supporting documents used to acquire health-insurance status or register as a dependant; it does not announce new enrolment criteria.
What changes?
NHIS branches can manage and share cases involving suspected forged or altered documents and the checks carried out. When someone with an existing verification history submits documents again, a branch can consult that history and check their authenticity again. Cases identified through different submission channels can therefore be used by branches nationwide when assessing insurance status.
The system supplements existing checks. NHIS says it already used Apostille and other official authentication evidence to check foreign-issued documents such as family-relationship and marriage certificates. Differences between countries in document formats, issuing and authentication procedures, and submission channels made some checks difficult.
Who is affected?
The announcement is relevant to people submitting foreign-issued evidence to acquire health-insurance status or register as a dependant, including foreign residents in that situation. Being a foreign national does not, by itself, mean that new documents must be submitted.
Are new documents or a new application required?
The release does not introduce a new universal document list, a new Apostille requirement for everyone, or an additional procedure for all foreign residents. It also does not describe a general change to enrolment criteria.
For an individual application, continue to ask the NHIS branch which evidence is required for the issuing country and your circumstances. The release does not provide a detailed checklist for every situation.
What about existing members?
The release does not announce that all existing members must resubmit their documents or enrol again. That does not mean documents cannot be checked again: the system expressly allows branches to consult previous checks when documents are resubmitted. It is not an announcement of automatic loss of cover.
