Magnitude TelescopeReason about digit value

MISSION TEXT

A code uses five places. The 6 is worth 60,000; the 4 is worth 400; the 9 is worth 90; and the 2 is worth 2. No thousands are named, so a zero must hold the thousands place and keep every other digit in its stated position.

Which number matches all the clues?
