Even when transferring between myself and a freind who lives elsewhere with a different address/name?
Correct.
On the Ultimate Rewards page, there’s a spot to “transfer to household member”, you put in their card number and last name, and transfer as many points as you want (name/address/location does not matter).
When you’re done, make sure to unlink their card otherwise they won’t be able to receive from anyone else.
This is considered a “safe way” that brokers buy UR points.
