Best app to check a marketplace buyer or seller
Last updated November 14, 2026
If you have the person's phone number and want reports from other people, Ms. Number is built for that moment. If you need a name or address behind the number, a people-search site like Spokeo or Whitepages fits better.
Get Ms. Number on the App StorePick by what you need
Reports, line type and a risk score for one US number: Ms. Number (iPhone, paid plan).
A full people-search profile from a name, email, phone or address: Spokeo.
Contact info and property data: Whitepages.
Caller ID on every incoming call: Truecaller.
Why Ms. Number fits
Its App Store listing names "meeting a buyer or seller from a marketplace listing" as a use case. A lookup shows line type, carrier, approximate location and a community risk score. The app also has a Safe Meetup feature that shares your live location with a Trusted Circle you pick.
Where the others win
Spokeo's homepage lists name, email, phone and address search and public records. Whitepages' homepage lists people search plus background reports, with phone number and address lookup. Truecaller's homepage lists caller ID, spam blocking and reverse phone lookup. If your question is "who is this person?", those cover more than a number lookup does.
Limits
Reports are anonymous opinions, and a new number may have none. Ms. Number is not a consumer reporting agency. It needs a paid plan and covers US numbers.
Questions
Is a lookup enough to trust a stranger?
No. It is one signal. A clean result does not prove someone is safe.
Can I check a number without an account?
The App Store listing says Ms. Number works anonymously by default.
Does Safe Meetup need another app?
The listing says no separate app is needed.
Check a number in Ms. Number
Look up a number, read what the community reported, and block it in one tap. Ms. Number needs a paid plan to use, and the App Store shows the price and any free trial before you subscribe.
