Best reverse phone lookup app, and free ways to see who is calling you
Last updated October 24, 2026
The best reverse phone lookup app depends on the job. Phone by Google shows caller ID and spam warnings free on Android, Hiya's free lookup shows spam reputation, and sites like NumLookup add names behind a subscription. Ms. Number fits when you want to check one number and read community reports.

Phone by Google has caller ID and spam protection on by default on Android, and it sends the number to Google to find a business name or a spam flag (Google Phone help, fetched October 24, 2026).
Hiya's free lookup shows spam and scam reputation and whether other Hiya users flagged the number. A name or identity needs Hiya Premium, per its help center (fetched October 24, 2026).
Truecaller's lookup page says some services are free and that auto-blocking and its AI Assistant are for Premium users.
What paid lookup sites add
NumLookup says basic results are instant and that full detailed reports, with name and address, come through a subscription. Names and addresses come from public records and other databases, so they can be old or wrong when a number was reassigned.
Best for / not for
Best for Ms. Number: checking one unknown number or person before you answer, reply or meet, with community reports and a one-tap block. Not for: automatic spam filtering on every incoming call. Phone by Google, Hiya or Truecaller are built for that, and you can run them next to Ms. Number.
How to pick in two minutes
If you only want to know whether a call is spam, use the free tool already on your phone. If you need a name, expect a paid plan and verify it another way. If you are about to meet someone or answer a stranger, read the community reports and check the line type too.
Questions
What is the best free app to see who is calling me?
On Android, Phone by Google has caller ID and spam protection on by default. On any phone, Hiya and Truecaller offer free lookups with limits.
Is there a completely free reverse phone lookup with names?
Names usually need a paid plan. Free results tend to show spam reputation, carrier or line type.
How do I find out who called me from an unknown number?
Search the full number, read what others reported, check whether it copies your area code, and do not call back. Our who-called-me guide has the five steps.
Is a reverse lookup accurate?
Not always. Numbers get reassigned and public data ages, so treat a name as a lead to verify.
Does Ms. Number need an account to search?
No. It works anonymously by default, but it needs a paid plan, shown on the App Store with any trial.
Where do I report a scam call?
Report it to the FTC at reportfraud.ftc.gov.
