There is many disinformation information about SSN for G4 visa holders. I can say based on my experience with 6 months consultancy contract wit the UN.
You will get SSN without any problem ! All you need is application form and your passport with G4 visa. You needs to fulfill application and visit social security card center in Manhattan is on 123 Williams street (close to Brooklyn bridge) and your card will be send to you in two weeks. You can get only one SSN for your family if your spouse will apply for work permit the she/he will need to apply for another SSN.
