I am interested in getting an Asian provider of the site datecheck but I was reading the site they check you out by calling your work! I am self employed so I was windering if anyone knew how that would work in relation to that site or verifaction in general.

Call or email them and ask. They're pretty helpful.

Many of the ladies on Date Check advertise elsewhere, and will see you.  Some even post often on TER, ask for a reference for date check.  It's how I got there.

If your business is searchable by Google, and you are as well, they will take care of you.

I had the same issue with P411. Gina was able to verify me through the providers.
