Verified Caller Identity Card
Design an incoming-call experience that shows identity information the caller has explicitly verified and shared, without covert imaging or detection.
The brief
Understand the problem
Background
Unknown calls may be legitimate deliveries, clinics, banks, or scams. A profile photo alone is weak evidence, and collecting an image from the caller without consent would be invasive and unreliable.
User context
Laila receives a call claiming to be from her bank's fraud team. She needs to know what has been verified and a safe way to continue without reading account secrets aloud.
Product problem
The interface must distinguish phone-number reputation, organization verification, contact-book data, and user reports while never presenting one signal as proof of intent.
Objective
Create an incoming-call identity card, verification detail, safe callback, and reporting flow.
What to design
Define the experience
Required experience
- Incoming call identity summary
- Evidence and warning detail
- Verified callback path
- Block and report
Screens and states
- Incoming call
- Identity evidence
- Safe callback
- Report outcome
Core user flow
Follow the critical path
- 01
Laila sees the claimed organization and verification status
- 02
She opens details without answering
- 03
She declines and uses the bank's verified in-app callback
- 04
She reports the original number as suspicious
Product rules
Requirements and constraints
Requirements
- Attribute every identity signal
- Never capture a caller image without consent
- Offer a callback using independently verified contact details
- Avoid exposing private contact labels to other users
- Support block and correction requests
Constraints
- Caller ID can be spoofed
- Some legitimate organizations use shared numbers
- The phone operating system limits pre-answer interaction
Reality check
States worth considering
Ready-to-use content
Mock data
Use this content to test hierarchy and realistic data states. You can expand it when the concept needs more depth.
Call evidence
- Claimed caller: North Bank
- Number not listed on the bank's official site
- Similar calls reported by 18 users this week
- Safe option: call through the North Bank app
Finish line
What to deliver
- Four mobile call states
- An evidence hierarchy that avoids a single misleading trust score
