Roughly 20% of surveyed local governments followed the wrong procedures when linking My Number with disability records, according to an interim report on recent issues with the identification card system.

Amid a number of errors concerning the integration of My Number and several governmental services, insurers had connected health insurance cards to the My Numbers of different people in over 1,000 cases.

The report, released Tuesday, also mentioned errors including inconsistencies between My Number and the pension records of public servants.
