Hi there! I understand you want to update or correct the phone number associated with your MAC.BID app account, is that right? Could you tell me if you’ve tried updating the number within the app already, or if you encountered any error messages during the process? That will help me guide you better.

In the meantime, here are some general steps you can try to update your phone number:

1. Open the MAC.BID app on your device.
2. Go to your account settings or profile section, where personal info is managed.
3. Look for an option to edit or update your phone number.
4. Enter the correct phone number and save the changes.
5. Sometimes the app may send a verification code to the new number—make sure to complete that step if prompted.

If you’re unable to update the phone number this way, or if the app doesn’t allow you to change it, one alternative is to contact MAC.BID customer support directly. You can reach out via email at [email protected] or by phone at (412) 200-5207 during their support hours, Monday to Friday, 9AM to 6PM EST. They should be able to verify your identity and update the number for you from their side1.

Please let me know what you've tried and if any error messages appeared. I'm here to help you through this!
