Check the provider's website.

Or pick an unreviewed girl off backpage. No screening usually. Just an LE check.

What you really should do before asking any more basic questions is to read the self-help section, includng the acronyms, plus search many pages back on this board.  Like the question you just asked, every imaginable question has been answered before.  Once you've done your homework everyone will be happy to help with anything else that comes up.
Many providers will want to know your real name, but they also will want references (see above for how to get them).  The most uncomfortable part of this game is giving up personal info (along with LE fears, the possibility of gettng outed and STDs).  If you want to play, you'll have to get comfortable with giving up some level of info or find another way to  get laid.  Everyone has his own comfort level and you'll have to find yours.  Good  luck!

but consider this fact:

Who is most likely to not care about careful screening?

It would be LE, and providers who attract LE (And often flip, meaning that they snare clients for LE.)

So, consider that side of the equation also.

I feel far more comfortable with a provider who screens carefully because they are the most reputable ones.

First of all, flat out ignore any advice you get here about putting your credit card into websites like date check. Those sites are scams and people here who promote them are shills. NEVER EVER use your credit card for any part of this hobby.

To directly answer your question, it's tough to start. I never give my real name or contact info, and neither should you. While most girls in this biz are reputable, some are drugged out. Would you want to have some drugged out prostitute knowing your real name, address, where you work, phone number? What if the agency that demands that info gets busted?

You need a monger phone, another email address and that's it. You will need to contact girls who will see you and build referrals. Avoid agencies. Once you build referrals in this biz you're set.
