Identical twins. Even then, mutations in somatic cells might cause negligible variation.
For the most part, our DNA is VERY similar. Only about 1% of our genetic material varies from one individual to the next, even across species. We share about 90% of genetic material with bananas... which is more than we do with dogs.

If you choose the right markers you can match just about anybody that you want to. That's why DNA identification tests target areas of the genome that have high variability that are unlikely to match two unrelated people for a large number of the markers used. But yes, if you developed your own test, you could find a match between everyone if you wanted to.

Yes. The closest matches would be siblings. But everyone has mostly the same DNA.
ndrw3987 - I've met banannas that are smarter than some people. Could it be in the DNA?

Yes. Every person's DNA mostly matches every other person's DNA. And we share a lot of the same DNA with every other mammal, too.

Yes twins have the same DNA.

Relatively speaking, no two people are more than 0.1% different in genomic base pair sequences.
Of course no two people (no even identical twins) are absolutely 100% the same.

Identical twins are clones of each other. They come from the same egg and so have the exact same genetic sequence.
