There's multiple reasons:

1) To confirm your identity before approving you into the network
2) To confirm your identity when you send in your W9 tax form
3) To keep as much fraud out of the networks as possible

CPA Networks are bound by privacy laws and can never give out your information, unless your information is subpoenaed in an investigation or whatnot.

It's like when you're going to buy a car, when you apply for credit, they're gonna ask for your ssn, personal friends, and even sometimes your previous tax records. It's all about preventing fraud, too many scammers out there, all they're trying to do is protect themselves and in doing that, you as well.

Fraud......

I think this thread here that can help you.

I tell you what most of these CPA network really sucks.You can sign up with some of them but they typically approve your account.However sometimes they want information which is unnecessary as you said about SSN.Now a user from Bangladesh or any other developing country dont have a ssn that means he cant sign up with them which is really irritating.

I think this is only apply on USA publisher rest world publishers are free not put it there . Because USA govt had record of each person income and activity .

if they don't have SSL, don't use them - plain and simple. complain to them.

Fraud
Tax
Etc

get legit, set up a company and get an EIN if you don't want to use your SSN

We can say to the necessities of security

Thanks CPATrendPhil for your nice explanation. I am completely agreed with you.
