Additional cardholder on credit card

[JamMakingWannaBe]

I have a Virgin Money Credit Card in my name with DH as an additional cardholder.

If I freeze my card, is his also frozen or can he continue to use it?

Google and the Virgin Money website are not helping.

I'm fairly sure you can just freeze one - they have different 16 digit numbers. I lost (turned up weeks later down the side of the car seat ) my card on DH's account a few years ago and his still worked.

Yes you can.The cards have separate numbers. I share an American Express account with my DS( for my benefit!)
I froze mine temporarily when I mislaid mine
