How to see blocked numbers calling on iPhone ?

Hello kirtika257.

Thanks for reaching out to Apple Support Communities. We understand that you want to know if it is possible to see blocked phone numbers. We will be glad to assist. There is no way to view a phone number that is blocked, however you can avoid unwanted calls. Check out the following:

"Send unknown and spam callers to voicemail

Go to Settings  > Phone, then tap any of the following:

• Silence Unknown Callers: You get notifications for calls from people in your contacts, recent outgoing calls, and Siri Suggestions.
• Call Blocking & Identification: Turn on Silence Junk Callers (available with certain carriers) to silence calls identified by your carrier as potential spam or fraud.

Avoid unwanted calls on iPhone

Hope this helps.

Cheers.
