It all depends on what you want to call your "identity". According to most spiritual traditions, they refer to the Ultimate Reality, the source of your consciousness and awareness of your own existence, as the truest form of "I-ness"/Subjectivity capable in this domain, which is also appropriately called the Self.
How to tell what your true identity is? Give up everything and see what's left
One can only surrender form as illusion, one cannot surrender Truth, which stands on its own when all obstructions are cleared.
But if you want to include the individual personality, body, mind, etc. as identity, then it would apparently seem like there are individuals out there. But the truth is, all supposed individuality is sourced by God-consciousness, i.e. multiplicity stems from unity. Once the ego is sufficiently cleared this becomes more and more apparent -- the body-mind does everything by itself, without a "me" to control things.
