How to track a missing money order?

What does it mean if you enter your exact serial number in to track your money order and nothing comes up?

• I went to the USPS website clicked Track and Confirm and nothing came up

• Answer:

  it hasn't been delivered yet.meaning it's intransit . once it's delivered the info. will be updated. you are talking about the pkge. correct? if you're talking about the m.o., it won't be updated until it's cashed..and it wouldn't necessarily be cashed at the p.o. so if the individual you sent it to deposited it i his bank it takes time to go through the bank system and then the p.o. before it shows up cashed. the p.o. makes good on all lost items, so you've no panic there as long as you kept the original purchase receipt and m.o. stub. hope this eases your mind
