Receiving? no. Sending? yes. When sending all transfers are final once the money is picked up. I use western union every single month. You can send online a limit of only 999$ anything more has to be in a store. If you are picking up you just show ID with your MNTC number (or whatever it is called) and you get your cash. Only if you don't have ID do you need to answer the secret question and answer (which is optional for the sender)
When an individual sends you cash make sure they use first-middle-last name (you entire full name) if someone in your country/city shares the same name as you (first and last) even with ID they will refer you back to the sender.
edit: I mean receiving is super safe. Sending is not safe as you can be ripped off super easy
Do you mean the other way around? How is it not safe to receive then, what could go wrong for me?
Yes its safe to receive, But If you receive black money then you might get in trouble..
Its nearly impossible to reverse the transactions,even if ur client get scammed..
Its safe to receive it, as in WU won't be able to take it back once you pick it up. But you do have to give out your address, as the question code system can usually freak out the sender.
It's pretty safe for being flagged by revenue services depending on your country. Haha. Make sure to report income received by WU. Tax departments get notified about those payemnts and they are checking them very intensly in richer countries.
