Western Union is an international money transfers provider. They are especially useful for transfering money from one country to another if the sending party or the receiving party does not own a bank account. They are active in over 200 countries with over 400 000 branches and payout places. The money recipient needs to provide an identity document and needs to know the money transfer control number (MTCN) which identifies the transaction.
When you consider all advantages and disadvantages of Western Union, you will probably come to the conclusion that it is definitely not the best way to send money. The sending fees are very high and currency conversion rate not very good. There are many other good alternative options such as a bank wire transfer, Skrill, Neteller, Paypal and others. I would only use Western Union in emergency situations when I cannot use any other method
Western Union is also often used in various scams when a person asks you to send money via Western Union to receive some item or pay some expenses. You may also receive faked Western Union payment confirmation from a person who wants you to send him/her some item. Therefore you should be extra careful whenever someone wants you to use Western Union. Generally speaking, credit cards are much more convenient and wire transfers and online wallets (Paypal, Skrill, Neteller, Payza) more safe for most online transactioms.
Methods of deposit
You can also deposit by Paysafecard - prepaid cards that can be bought for cash in many places, most often at gas stations, newsagents and some grocery stores.
