Providers are getting tired of fake information and untruthful clients. Being raped, assaulted, robbed. If you don't have anything to worry, if you not going to hurt a provider why do you worry about.  

Agencies & independent providers want a regular business, not drama with your wife.

I will request a copy of a person’s drivers license after they’ve exhausted all other resources for verification or if they just prefer to send it to me to get screened quickly. I also let the person know that they can blur all details outside of the name, date of birth, issue and expiration dates.  

However, I have multiple other methods of screening as well.  

Just do whatever you’re comfortable with. If it’s beyond your comfort zone, respectfully decline and move on.
