How does Ms. Number work?
Last updated November 14, 2026
Enter a US phone number and Ms. Number shows what people have reported about it, along with the carrier and a severity score. Block Browser INC makes the iPhone app. The companion website, msnumber.app, handles lookups, accounts and billing.

Community reports with tags such as scam, robocall, debt collector, telemarketer, harassment, spoofed or safe.
Line type (mobile, landline, VoIP or toll-free) and the carrier.
A severity score from safe to fraud.
The App Store listing also describes caller ID for unknown numbers when a name is available, plus one-tap blocking.
Free preview versus paid
Ms. Number's site describes a free preview that's open to anyone. The full community thread and carrier reveal require a subscription. The App Store listing says you need a paid plan to use the app.
What it is not
Ms. Number isn't a consumer reporting agency. Its site says results must not be used for hiring, housing, credit or insurance decisions. Community reports are written by users and are opinions. The site also says its data may be inaccurate. US numbers only.
