Can’t add my wife as an additional cardholder on my credit card, because she once used her phone number on a Barclays account of her own.
Unfortunately this somewhat makes sense… Now, if her account has been closed, then this is a design flaw. But if it’s still there - just hasn’t been used in ages - then this sanity-check makes sense to prevent fraud.
It’s perfectly reasonable for a couple to have their own accounts plus a joint account.
True. I guess given that the way I’ve always done it here (one contacts the bank directly to open a new joint account) rather than trying to add a second person to an existing account, I hadn’t considered that approach. Still, I can somewhat understand the rationale behind this design.
also mobile numbers are a bad identity vector. Some keep theirs for decades, others may change them several times a year every year.
