Are any two electrons, or other pair of fundamental particles, identical?

If we were to randomly select any two electrons, would they actually be identical in terms of their properties, or simply close enough that we could consider them to be identical? Do their properties have a range of values, or a set value?

They are so identical that the state with electron A in state 1 and electron B in state 2 is **exactly the same state** as electron A in state 2 and electron B in state 1. This indistinguishability has measurable effects, most importantly it is evidenced by the statistical properties of ensembles of particles.
