Frequently asked questions

Is the tool free?
Yes. Free 1 lookup/IP/24h. Register free for 5/day. Pro 279K VND/month via PayOS = 1,000/day + bulk. Business 559K VND/month via PayOS = 10,000/day. Resets at midnight Vietnam time.
Where does the database come from?
From a UID-to-phone mapping dataset publicly circulated since 2019, filtered and normalized for the Vietnamese market. The tool does not collect new data and does not access Facebook. Results are for reference only and may be outdated or inaccurate.
Is looking up UIDs legal?
Already-public data used for identity verification. Users are responsible for complying with applicable law. Do NOT use for spam, cold telemarketing, or fraud.
What is the lookup success rate?
A result is available only when the UID exists in the available data. Because the data is from 2019, some numbers may have changed, and Page or international UIDs may return no result.
What is a UID and how do I find mine?
A UID is the unique numeric identifier for a Facebook account. Go to a profile → the URL shows ?id=100012345678 → that is the UID. Or paste the profile link directly and the tool converts it automatically.
Can I check multiple UIDs at once?
Yes with Pro+. Go to App > Tools > Bulk UID to Phone, paste up to 10,000 UIDs at once, export as CSV.
The phone has masked digits — how do I see the full number?
Upgrade to Pro or Business for full numbers. Masking applies to Free/Starter users to prevent abuse.
Are there usage limits?
Free: 1/IP/24h, masked number. Pro: 1,000/day, full number. Business: 10,000/day, full number + bulk. Resets at 00:00 Vietnam time.
