Troubleshooting Amissa App Registration Issues

Last updated: March 23, 2026

If you're experiencing problems during the Amissa app registration process, here are some common solutions to help you complete your signup successfully.

Common Registration Issues and Solutions

Incorrect or Unknown Invitation Code

A unique invitation code is required to securely connect you to your healthcare provider. You should receive your code via email from your healthcare provider.

The invitation code is different from other codes you might get for verifying your email address or phone number. These codes are all necessary to protect your privacy and verify your identity.

Unable to Confirm Registration

If you're unable to complete your registration, first check that all required fields are properly filled out:

  • Birthdate format: Ensure your birthdate is entered in MM/DD/YYYY format (2-digit month and day, 4-digit year)

  • Phone number: Verify your phone number is entered correctly

  • Required fields: Double-check that all mandatory fields are completed

Email Verification Code Not Sending

If you reach the email verification code step but aren't receiving it by email, the issue may be related to incomplete or incorrect information. Make sure your email address is entered correctly. If you still have trouble, get in touch with us and we can help.

When to Start Fresh

If the above solutions don't resolve your registration issues, the most effective approach is to start over with a clean installation:

  1. Delete the Amissa app from your device

  2. Reinstall the app from your device's app store

  3. Use the same invitation code you received originally

  4. Complete the registration process again, ensuring all information is entered correctly

This fresh start approach often resolves persistent registration problems and allows you to complete the signup process successfully.
