How to find people on instagram with phone number?

That's a feature Instagram (Meta) provides, but it relies heavily on both your permissions and the other person's privacy settings. You can't just type a number into a search bar, but you can sync your contacts. Here's the step-by-step process on the Instagram mobile app: 1. Go to your Profile (tap your photo in the bottom right). 2. Tap the three lines (☰) in the top right corner to open the menu. 3. Go to 'Settings and privacy' > 'Account Center' (it’s a Meta thing now). 4. Under 'Account settings', look for 'Your information and permissions' or 'Upload contacts'. 5. Find the option to 'Connect contacts' or 'Sync contacts'. Turn this feature ON. Instagram will now regularly upload your phone's contact list and suggest people who have used that same phone number to register or link to their Instagram account. If they have set their profile to NOT be found via phone number, you still won't see them.
