There is no licence, so there is no number
Willow Creek Home Finance is a fictional company built to demonstrate a website. It holds no lending licence in any state, is not registered with any regulator, and has no registry identifier.
Why an invented number would be worse than none
Lending registries issue identifiers in a predictable format. A number made up to look right can therefore collide with a real, working loan officer or company — someone who has done nothing except be assigned the identifier that a demonstration site invented.
An earlier version of this site carried exactly that: a plausible seven-digit company identifier and a per-officer identifier on each team profile. Both are gone. So is the link that invited a visitor to "verify our licensing", which pointed at a real public registry that has never heard of this company.
What a real lender must disclose
A real residential mortgage lender or broker in the United States would carry its unique registry identifier on its website and in its advertising, would list the states in which it is licensed with the licence number for each, and would give consumers a route to verify all of it independently. Loan originators would carry their own identifiers.
If you are checking a real lender, the registry is public and free to search, and the identifier on their site should match the record exactly, including the legal entity name.
Equal housing
A real lender would state that it does business in accordance with the Fair Housing Act and the Equal Credit Opportunity Act. Those laws bind real lenders. This site is not one and does not claim their protections as a credential.
