Avoid and/or delay giving your real last name as much as you can.

First of all, on a web form that is not HTTPS (which 99+% of provider web forms are), your real name will be sent from your browser to her site/database/form in cleartext which will be easily discovered by LE if they are packet sniffing.  

Second, since you are a newbie, your conversion rate of intial contacts to actual dates will be lower than 100%.  So delaying giving out your real name will minimize your exposure to women whom you actually met and are more invested in keeping each other safe.  

Third, even if you actually meet this woman for a date, there's no telling what she could do with your real name if God forbid things go sour for some reason (extortion, blackmail, etc).

Fourth, even you clear the above levels, and she is forever the kindest, sweetest, innocent kitten provider of your dreams, she may not take care to destroy your information or keep it secure somewhere.

Since you have your "member number from a reputable service that has verified" you, I suggest giving just that and make sure she can look up your profile on said reputable service and link your e-mail with which you are e-mailing her from.   That demonstrates that the person e-mailing her is screened / referenced.

Finally, there are some cases where a provider/agency will insist on seeing ID.  Alas, you will have to decide whether she is worth it for that or move on to other pretty fish in the sea.  Ask ahead if they check to avoid an awkward situation.  Some agency websites say they check ID.

Let me get this right, you're a newbie have found a lady who will see you with no refs and you wanna find away around giving her the info she needs to be comfortable seeing you?

you're off to a great start.

Give her ALL the screening info she requires or move on to someone who's requirements match your comfort level.

great way to start off a session by trying to get around her rules. All that does is make a provider thing you will also be difficult in person.

you wanna be that guy?

Why not join date check or preferred 411 verification sites....

if you do not have provider references they will verify you through your real name and employment

but

it is MUCH safer to give this information to these services than it is to providers

Many (certainly not all) of their member providers will then see you without requring your real name. My advice would be to stick with those who will screen through verification sites and the referrals you accumulate and not let your real name and info get out there.

providers are too fast and loose with gentleman's information these days. If you miss an appointment even due to the most legitimate reasons, you run the risk of having your real name and contact information posted in various places as a NCNS (no call no show)

An hour of sex is not worth the risk of having your name get out there.

In general failure to fill out a gal's info form completely will land you quickly in the reject pile.

Every provider has her own screening criteria.  Some accept references from agencies, some don't and some accept them from some agencies but not from others.  

You have to decide what information you are comfortable giving and also realize that how much you are willing to divulge will often effect which ladies will and will not see you.
