Some banks will let you create new accounts through their mobile app or online banking app. Even for new customers (some banks have no physical presence).

And most banks that I'm aware of will let existing customers create new accounts with distinct routing/account numbers online.

Not in the US. Especially unique routing numbers. Maybe you mean virtual credit card numbers.

Sorry, I edited "distinct ACH info" to "distinct routing/account numbers" to be more clear, but evidently it was just differently-confusing!

A bank will only have one or a small number of routing numbers.

My point was that most banks will let existing customers open new accounts online. This will create a new routing/account number combination that you can share with the service you don't trust enough to share your primary account with.

You can also add a (new) debit card to the new account, and some providers let you create virtual cards at will. But that's not what I was talking about.
