A lot of people are having a problem with providing the last 4 digits of ssn. I don't see where this is relevant in determining age. Also some sites are asking not only for a drivers license but want the license number also. Again, not relevant.Frankly, anyone not using age verification will not be in business for very long. FDA has long been known to have geared up to do test purchases both in B&M and online. And guess which is easier?
