Yes. Just do the math.
There are only 10,000 combinations of 4 digits.
They are able to do a credit check based on the last four + your name and address. The chances that there are 2 John Doe's with 9283 at the same address is almost impossible.

Of course not. There are only 500 people in the world. Otherwise, why would you keep running into people you know?
No, seriously... Remember that, given 22 people, there is about a 50/50 chance of some two having the same birthday. With the last 4 digits of SSN, it takes only about 140 people have about a 50/50 to hit 50/50 chance.

There's almost 3.5 billion possible SSN's, but as it's been pointed out, only 10,000 possible combinations for any specific 4 of those numbers.
So yes, there's likely to be about 30,000 people sharing the last 4 of your social security number, assuming 300 million people in the US and an even distribution.
But as was also pointed out, the chances that any of those 30,000 people sharing a last name, address, city, etc..., and especially a combination of those items, is slim to zero. There's probably hundreds of thousands of last names alone in this country, putting the odds in the trillions or more. My calculator won't go high enough to figure out what 30,000 against even 100,000 last names would be.

Yes, definitely. However, establishments do not just use the last four digits of the social security alone to identify a person but in combination with something else such as your name and your address. Such a combination makes any duplication very unlikely.

Yes, I work using an employee database and to protect employees full ss# we ask that they put their last four digits of their ss# on the class roster and when it's time to find that number multiple employees's names show up.

They would have to. There are 300 million people in the US and there aren't that many possible combinations of 4 numbers.

Yes, many people have the same "Last 4". Statistically, 30,000 or so people have the same Last 4 as you do.
