...I have never had to since because of references. Go with a well reviewed provider with reviewers that have many reviews. You will be fine. Check out her photos with Tineye or Google. Google her phone number. If all checks out it's a go assuming she agrees to make the appointment.

only applies to those ladies who actually screen properly.  To me that's probably a good indication they care about their safety and some of that is going to spill over onto your safety.  

You can probably sneak through if you are shopping at some of the "malls".

However, I've never been asked.  I usually give them my phone number before the date, so when I call for for specific directions, she will know it's me and not another potential client.  As I have been doing this for a while, I have a good list of whitelist referrals, DC refs, and P411 OK's, so giving up much personal info is not necessary anyway.

I must add, I am single, no SO to worry about, and retired, so giving out personal info would not generally cause me any problems.  Many hobbyists, like possibly yourself, are married or in a relationship, so handing out personal info might be troublesome for them.

Most providers require references from 'LEGITIMATE, TER REVIEWED" ladies. If you are first timer, then you have no references so for you, either p411 or real info. will be the only way. Now, of course there are women who don't screen at all, but do you really want to see what her service is going to be like? If she is not screening, there is a reason...she needs the money that bad to risk her life for a few bucks. No screening should be more of a red flag, than a good thing.
