> you need to communicate your bank account number

in Latvia we need to do this for domestic payments anyway. We use IBAN even for domestic payments..

> and likely your legal name.

not mandatory. If provided, the bank tells you whether the recipient name matches the account, but if not, you can proceed with the payment anyway.

They made it mandatory in NL not long ago iirc, or at least the validation now is and the bank doesn't let me leave the field blank. It does seem to be okay with variants of the name

I, too, would prefer to just be able to give people a random number to send money to. Isn't that a GDPR requirement anyway: data minimisation? Can they legally require this beyond their 90% of the law (that is, custody of the thing I'm trying to move)?
