Declined by a bank
Banks don't share with WU the specific reasons for declined transfers. The decline could be related to the cash advance capability of your credit card, your credit card limit, a mistake when entering bank account information or other requirements from your bank.
Please contact your bank directly.
Declined by Western Union
Occasionally, money transfers may be declined. This is due to a variety of reasons, such as WU being unable to confirm your identity.
WU is required to comply with regulatory standards and internal policies. If these are not met, your money transfer may be declined.
If you were declined trying to send money online, you may be able to send money in person at an Agent location.
