Why this matters
An unverified locum is your exposure
A practising certificate runs a calendar year. If it lapsed on 1 January, the doctor covering your Saturday clinic is working without a current one — and the facility carries that exposure alongside them, not instead of them. A group chat cannot tell you either way: an MMC number in a message is not a check.
On Locum.my that check becomes a condition of the booking. MMC registration and APC validity are verified before a shift can be claimed, and every shift is logged as it happens.
