WhoseNo — Caller ID, Reverse Phone Lookup & Spam Call Blocker

Tired of answering unknown calls? WhoseNo gives you the tools to identify callers, check spam risk, and block unwanted numbers — all from one app.

REVERSE PHONE LOOKUP
Enter any phone number and instantly see community reports, spam risk status, and caller details. Whether it’s a missed call or a suspicious text, WhoseNo helps you find out who’s behind the number before you call back.

COMMUNITY SCAM REPORTS & VOTING
WhoseNo is powered by real users. Anyone can report a number as spam, telemarketer, or harassment — and the community votes to confirm. This means the data gets smarter and more reliable with every report.

SPAM RISK STATUS
Every number you look up shows a clear safety indicator: safe, likely spam, or unknown. No guesswork. You see the risk level at a glance so you can decide whether to answer, block, or ignore.

MANUAL BLOCKLIST & BLOCKING RULES
Take full control of who reaches your phone. Add specific numbers to your personal blocklist, or set up blocking rules to filter calls by pattern. Your phone, your rules.

WATCHLIST & REPORT UPDATES
Tracking a suspicious number? Add it to your watchlist and get notified when new community reports or status changes come in. Stay informed without having to check manually.

CONTACT SAFETY AUDIT
Run a one-tap scan across your saved contacts to flag any numbers with community spam reports. Clean up your contact list and know which numbers in your phone have been flagged.

SMART DIALER MODE
Replace your default dialer with WhoseNo’s built-in call experience. Access your call history, keypad, and incoming call screen — all enhanced with caller identification and spam alerts.

SAVE TO CONTACTS
Found a useful number through lookup? Save it directly to your phone’s contacts from the results screen. No copy-pasting needed.

OCR NUMBER SCAN
See a phone number on a poster, receipt, or screen? Use WhoseNo’s built-in scanner to extract the number from any image and instantly look it up.

BIOMETRIC APP LOCK
Protect your call history and lookup data with fingerprint or face unlock. Keep your phone activity private, even if someone else picks up your device.
