I have used that with almost every bank, Discover, Wells Fargo, Chase, Capital One. Surprisingly, few of different banks looked like had same third party printer/mailer i.e. mailed from same address. Just a tidbit, My work is paid by 1000s of Californians through these bill pay checks. Often we receive a thick stack (maybe 100) of these checks with sequencial serial numbers, same account & routing numbers, & each customer's unique identifier (for us to allocate money), all in same envelope or box. Its fun to go process those stacks.
