Verifying a membership card
Scan the code printed on the card with a phone camera. It opens a page that says whether the card is valid.
There is no way to look a member up by name or by membership number, and there will not be. A page that answered those questions would let anyone compile a list of the party’s members.
If you have lost your card, contact the party office. A lost card can be withdrawn so that it stops verifying.
