Comment SSN is not an ID (Score 1) 166
People doesn't seem to get it. The SSN number is not an ID.
It should only be useful for the Social Security. However, due to lack of alternatives, it's been bastardized as a general ID.
Also, you are a bunch of crybabies. In Brazil, we have:
0- Birth certificate
1- ID (requires 1 to get) (has photo)
2- CPF ('physical' person registry) (arguably redundant with No.1, but required for historical reasons). It has a status, which is tied to your income tax papers. If you do not pay the damn taxes, or if you fail to present proof that you are not required to annually (too low income, for instance), it gets 'dirty' and will not be accepted anywhere until you clear it up. (requires 1 to get, no photo so 1 is required almost everywhere you have to present this). This is what is commonly used as a natural key in databases.
3- Voting card, also with an unique ID (requires 1 and 2)
4- Military enrollment card (requires 1, 2, physical examination etc)
5- If you want to be employed (not a business owner, not in the military), you require something that looks very like a passport and records all your employment history. Rough translation would be 'Worker's wallet'. (requires 1, 2, 3, 4 if memory serves right)
6- Driver's license, if you drive. As it has a photo ID and has (1 and 2) written in it, it can serve as your ID for most purposes
I might be forgetting something, but the above are expected for all citizens. God help you if you are mugged with those in your wallet. It can take weeks to get new copies. And the birth certificate is the greatest pain of all, so almost everyone presents copies when required.
