What does 'lastupdated' in Myinfo JSON response signify?

The lastupdated attribute indicates the date on which the data was last updated in Enterprise Data Hub (EDH) or Myinfo. It does not reflect the most recent update made at the original Government source.

For example:

"mobileno": {
     "prefix": {},
     "areacode": {},
     "nbr": {},
     "classification": "C",
     "source": "1",
     "lastupdated": "2024-02-24"
}

In the above example, "lastupdated": "2024-02-24" means the mobile number data was last updated in EDH or Myinfo on 24 February 2024.

⚠️ Important: This does not mean the user changed their mobile number in Singpass on that date. It only indicates when the data was synchronized or refreshed in EDH or Myinfo, not when it was modified at the original source (e.g., ICA, CPF, etc.).
