Help
Unique identifier of the national registry (nn.nn.nn-nnn.nn). Can be found on the back of the patient's identity card and starts with year of birth (yy) / month (mm) / day (dd). This information is never transferred to Sciensano. In case the patient does not have a national registry id or the id is not known, an identifier can be automatically generated based on the 'name', 'first name', 'date of birth' and 'sex'. In this case, these four fields are mandatory.

This field can be used to enter an internal ID or reference number. It is available for internal use only and is not transferred to Healthdata. If there is an integration between HD4DP and your organisation's patient administration system, additional patient identification information such as date of birth, sex and SSIN can be automatically enriched based on this internal patient ID. Please do not encode the social security identification number (SSIN) in this field. The SSIN must be encoded in the field 'National registry ID of the patient'.
