## 概览

Num Lookup is a reverse phone and name lookup service for US numbers. You preview the full report structure for free, then pay only if a specific report is worth unlocking — useful for checking unknown callers, marketplace buyers and scam patterns before you engage.

## 定价与套餐

Free previews on every search with no signup or credit card required. A $1 one-day trial unlocks a report, then $10/month for 10 phone and name lookups. Cancel anytime. Unlocked reports remain in your search history for free re-access.

## 关键功能与能力

- **Reverse phone report:** Enter any US phone number to see owner name, current and previous addresses, carrier, line type, emails and possible relatives in one structured report.
- **Free blurred previews:** Every search returns the full report layout for free, with sensitive values blurred, so you can see which sections actually contain data before you pay.
- **Name-based people search:** Search by full name plus city and state to find contact information when you have a name but not a number.
- **Area code and scam guidance:** An interactive area-code reference explains what each code covers and which scams commonly spoof it, plus guidance on spotting spoofed caller ID and robocall red flags.
- **Aggregated multi-source data:** Results are aggregated from multiple licensed providers such as CallerAPI and FindNCall and normalized into one consistent, cached report.

## 主要用例

- **Identify a missed or scam call (Anyone receiving unknown calls):** Check whether a number that keeps showing up is a scam, robocall or legitimately registered line before you answer or return the call.
- **Verifying a marketplace buyer (Marketplace seller):** Confirm the owner and carrier behind a buyer's phone number before you accept payment, ship an item, or meet someone in person.
- **Safety checks on new contacts (Parent or online dater):** Check whether a contact's number matches the person they claim to be, a common concern for parents of teenagers or anyone meeting new people online.
- **Vendor verification (Small business owner):** Confirm that a vendor's callback or billing number matches the company it claims to represent, rather than a spoofed enterprise number.

## 优势
