Hi KNJayaraman,
Thanks for posting in Apple Support Communities! Since you're not seeing the contact in your Contacts or Favorites, check to ensure all accounts that your contacts are synced with are selected:
- Open the Contacts app, or the Contacts tab from the Phone app
- Tap 'Groups' in the top left corner
- Select any accounts that don't show a check mark next to it, or tap 'Show All Contacts' (bottom of page)
- Tap 'Done'
Once you complete these steps, check to see if your missing contact appears. If it's still missing, restart your iPhone as restarting can fix many issues. We also suggest ensuring your iPhone's software is running the latest version: Update your iPhone, iPad, or iPod touch - Apple Support
Hope that helps!
