    Please update your contact information as soon as possible so that alerts will be sent to the proper number on file. You will still receive alerts on your home phone number or email, if that information is on file. Accurate contact information is important so that we can reach you in the event we identify suspicious transactions on your account.

    SMS fraud alerts will come from 919-37. You may want to save this number in your contacts with a name you will recognize for future alerts. We recommend ‘Astera CU Fraud Alerts’. Fraud alert messages sent from this number will also be labeled with the Credit Union’s name.

Call Astera Credit Union at (517) 323-3644 or Toll Free: (800) 323-0048 immediately to report the fraudulent text message.

    There’s no cost to use the automated fraud alerts service. Astera Credit Union pays for all costs associated with sending and delivering the SMS fraud alert messages to your mobile device. This service is provided to you free of charge.

    SMS stands for Short Message Service and is also commonly referred to as a “text message.” With an SMS, you can send a message of up to 160 characters to another device. Longer messages will automatically be split up into several parts. Most mobile phones support this type of text messaging.

    A text message and/or pre-recorded voice call may be sent to your mobile device when there is a suspicious transaction(s) identified. Simply reply to the text to confirm whether or not you recognize the transaction(s). If you do not recognize the transaction(s), you will receive a text asking you to call 888-918-7313 for further assistance. There will be a block placed on your card to protect you from further fraud until you call us. If you reply to the text that you recognize the transaction(s), your card will remain available for use.

    If you do not reply to the text within 30 minutes, a pre-recorded voice call may be attempted to your mobile device and home number listed on your account. If you receive a pre-recorded call, please listen to the prompts provided to review and respond to the validity of each transaction that is presented during the call. An email will also be sent to the address on file to confirm transactions on the account. You can also call us at any time to validate the transactions or if you have any concerns about the message you received.
