Is looking up a UID legal?

The tool provides already-public data for identity verification purposes (e.g. shops verifying customer orders, companies checking applicants, users detecting scam accounts). Users are responsible for complying with applicable law. Do not use for spam, cold telemarketing, or fraud.

What is the success rate?

Approximately 60–70% of Vietnamese UIDs are in the database. Since the data is from 2019, some phone numbers may have changed. Page UIDs (60xxx prefix) and international UIDs typically return no result.

What is a Facebook UID and how do I find it?

A UID is the unique numeric identifier for a Facebook account. To find it: open a profile → the URL shows facebook.com/profile.php?id=100012345678 → that number is the UID. You can also paste the profile link directly and the tool will extract the UID automatically.

What is the difference between Free, Pro, and Business plans?

Free: 1 lookup/IP/24h, middle digits masked. Pro (199K VND/month): 1,000 lookups/day + bulk check, full number shown. Business (599K VND/month): 10,000 lookups/day + CSV export + group→UID export.
