You should double check the data that you are using to login (i.e. Last name and My WU® number, or Last name and Email) and make sure they match the latest information that you have provided to Western Union. If you can’t validate or are unsure of the information provided to Western Union, you can call our Customer Care at 0800-100-609 to retrieve or update the relevant data points, including your My WU® number, email address and phone number. Using My WU® number or email address (together with your last name) is the most reliable way to check your balance or redeem rewards.
