NumLookup is a website that takes a US phone number, or a name plus a city or state, and returns what it says is a profile of the person linked to it. One basic search a day is free, and fuller reports need a monthly plan in US dollars.

This review looks only at numlookup.com, and the pages we went through on October 29, 2026 were its homepage, FAQ, signup page with the plan table, about page, privacy policy, terms, opt-out form, people search, reverse image search and API pages, plus registry records for the domain and several lookalikes. We ran no search on any number or name, so nothing below describes a real report or tests accuracy. What a report holds is taken from NumLookup’s own pages and sample reports, and each fact links to the page where we read it.

Because the service handles data on people who never agreed to be looked up, we also cover the legal lines, using the FTC staff text of the Fair Credit Reporting Act and the European Commission’s GDPR guidance.

The Service at a Glance

What a Search Is Supposed to Return

The NumLookup homepage asks for a 10-digit US number. Free results, it says, load at once and cover the name, location, wireless carrier and phone type, while a subscription adds address history, relatives, demographics and background details.

Its feature list names six report blocks:

  • owner identity, with name, age and a demographic profile
  • address and location history
  • a spam and risk score built from reports by other users about scam, robocall or telemarketing calls
  • relatives and associates, up to a dozen people, which the page says is useful for skip tracing
  • carrier and line type
  • a confidentiality promise that the person searched is never notified

Where NumLookup Says the Data Comes From

The homepage says each number is checked against public records, telecommunications databases, carrier information, business directories and other publicly available records. Its step two widens that to public, licensed and proprietary data sources.

The privacy policy carries a September 22, 2025 update date and gives a longer list of seven source types:

1. phone directories such as public white pages

2. the open web

3. consumer indexes, described as age, name, address and demographic data that people gave to third-party survey companies

4. email databases

5. property records such as deeds and assessor files

6. public social network profiles

7. business directories

The same policy says NumLookup never shares passwords, court or arrest records, credit scores, card details, financial data, or Social Security numbers.

Intended Users

The consumer site pitches caller identification with spam and robocall flags. The API page targets companies, listing fraud and risk checks, lead enrichment, identity verification, contact centers, contact data quality, and debt recovery and legal work. Vetting a tenant, applicant or borrower is ruled out by NumLookup itself, as the legal section explains.

Who Runs the Site

The privacy policy names NumLookup LLC as the provider of the website. According to the about page, NumLookup is made in Atlanta. That page gives hello@numlookup.com and the phone line +1 (844) 405-2145 as contacts, and states a mission to “make the world more open and transparent”. We found no street address or company registration number on the pages we read.

Inconsistencies We Noticed on the Site

Several statements on numlookup.com do not agree with each other.

  • Financial fields. The report the homepage presents as a sample includes Income, Estimated Credit Rating, Home Value and Net Worth fields, yet the privacy policy says the company never shares financial data or credit scores. No explanation for that gap appears on the site.
  • Search history. The signup page FAQ says activity on the site is fully anonymized for privacy, and the about page calls searches end-to-end encrypted. The privacy policy, though, says NumLookup keeps a record of each search a user runs, and the terms say it collects user datapoints for each request and will give them to law enforcement when legally required.
  • Image index size. The reverse image search page says its database holds more than 10 billion images, and further down describes an index of more than 100 billion.
  • Audience claims. The homepage and about page say NumLookup is ranked number one on Google for “reverse phone lookup”, has 5M+ monthly users, indexes 600M+ phone records and carries an average user score of 4.8 stars. These are NumLookup’s own figures, the rating has no named source, and we did not verify them.

Running a Search, Step by Step

The homepage describes three steps; we did not run them.

1. Type the number. The box accepts a US or Canadian number. A separate tab on the people search page takes a full name plus a city or state instead.

2. Let the site match records. NumLookup says it scans billions of records at this stage.

3. Read the report. The free view shows basic fields. A paid plan unlocks the full report, which the people search sample groups into Overview, Contact, Addresses, People and Records.

The FAQ explains the messages: a masked name usually means the daily free allowance is used up. “This Phone Number is Blocked” can mean the owner asked to be removed or that legal compliance rules apply. “Proxy IP Detected” appears when a VPN or proxy is active, and the terms forbid using those services with the site.

Free Allowance and Paid Plans

The FAQ allows one phone number lookup per day at no cost and without registration, and claims over 99% of users need no more while only 1% pay. The signup page adds that social media links appear only to paid members, and the Premium plan lists an ad-free experience, which suggests the free view carries ads. The homepage code also loads Google Tag Manager and Facebook scripts.

Monthly Plans in US Dollars

The plan table on the signup page, checked October 29, 2026, priced three subscriptions in US dollars per month:

Plan Price (USD) Phone and name lookups Plagiarism checker Other listed items
Premium $10 per month 40 per month 20K words per month Ad-free, unlimited reverse image searches, PDF reports
Professional $20 per month 80 per month 30K words per month Adds fast search; NumLookup labels it its popular plan
Business $50 per month 200 per month 200K words per month Adds premium support

Larger volumes are quoted by email, and the plans live on /signup, since /pricing returned a 404. The terms let NumLookup alter prices with no prior notice, so check the table before you pay.

Renewal, Cancellation and Refunds

The signup page says plans bill automatically every month. Cancel from the account under My Plan & Billing, per the FAQ, or by email as the terms describe. Cancelling before the renewal date stops the next charge, and a cancellation after a billing date earns no refund.

The Enterprise API Offer

The API page offers a separate enterprise product with 30 data points per request, US coverage across the North American numbering plan, and a spam score from 0 to 100. Pricing is per lookup under contract with a minimum yearly commitment, no rate card is published, and access is reviewed before a key is issued.

Privacy, Opt-Out and What NumLookup Keeps About You

The privacy policy says NumLookup records pages viewed, hovers, clicks, purchases, IP address, mobile number and device identifiers, using cookies and JavaScript tags, some possibly set by an outside provider for marketing analysis. For account holders it stores name, email, phone, payment data and passwords, and it keeps a search history. It infers location from your IP address. It says it does not sell or share that information.

Removing a Listing

If your own details show up, the NumLookup opt-out form handles removal from the phone lookup and the name lookup separately, with a tab for each. The privacy policy counts 31,826 removal requests during 2023, then 94,071 during 2024, states that every one was approved, and gives average completion times of under 30 days and under 20 days. We did not test that timing.

Age Rules

The minimum age for users is 18, and the terms bar using the site to look up children under 18. The privacy policy still warns that a search may surface public social profiles of people aged 13 to 18, removable through the opt-out form.

What the Policy Leaves Out

Searching the privacy policy and terms for GDPR, the EU or California found no mention, so neither document names rights for European or California residents. The policy does offer a right to know and correct through hello@NumLookup.com.

This section is general information, not legal advice.

US Rules on Screening People

Under the Fair Credit Reporting Act text published by FTC staff (revised March 2026), a “consumer report” in section 603(d) is information about a person’s credit worthiness, character, reputation, personal characteristics or mode of living that is used, or expected to be used, to decide eligibility for credit, insurance, employment or other purposes listed in section 604. Section 616 makes a person who obtains a consumer report under false pretenses, or knowingly without a permissible purpose, liable for actual damages or $1,000, whichever is greater.

NumLookup’s API page places its output outside the definition of a consumer report and forbids FCRA covered decisions, naming employment screening, tenant screening, and credit and insurance underwriting. Its FAQ answers “No” on employment or tenant screening. A NumLookup result should therefore not decide a job, an apartment, a loan or a policy; use a screening company that operates under the FCRA.

The terms add their own limits: no stalking or harassment, no illegal use, and no selling, telemarketing or robocall campaigns built on the data.

European Data Protection Rules

The European Commission’s explainer defines personal data as any information relating to an identified or identifiable living person, and lists a name, a home address and an email address as examples. A phone number tied to a name meets that definition, and principles such as purpose limitation and data minimisation apply to business processing of it.

The Commission’s page on individual rights lists the rights of access, rectification, erasure, restriction, portability and objection, and says an organisation should reply without undue delay and, in principle, inside 1 month. EU residents who find their details on a lookup site can start there. NumLookup’s own documents do not mention them.

Common Sense Limits

Checking who called before ringing back differs from profiling a neighbour or an ex. The NumLookup terms say the company does not guarantee accuracy and supplies information as is, so treat any result as a lead to confirm, never as proof.

Domain Records and Similar Addresses

The ICANN lookup for numlookup.com shows numlookup.com was registered through GoDaddy.com, LLC on October 25, 2018, with an expiry of October 25, 2027, and a last change on June 18, 2024.

Several near matches are not the same site:

  • numlookup.net was registered on January 9, 2026 through NameCheap. It runs a blog pairing phone numbers with the word NumLookup, with no link we saw to the real service.
  • numlookup.org, registered January 24, 2022 through NameCheap, describes itself as a tech, news and lifestyle site.
  • num-lookup.com, registered November 30, 2025 through Tucows, showed only a default hosting page.
  • numberlookup.com, registered October 6, 1999 through easyDNS, did not respond to our request.

RDAP had no record for numlookup.co, numlookup.io, numlookup.app or numlookup.us. Type the address yourself and never enter card details on a lookalike.

Points in Its Favour and Against

What Works

  • A basic search needs no account, and the FAQ states the free allowance plainly.
  • Plan prices, lookup quotas and the refund rule are published on one page.
  • An opt-out form exists, split by phone and name, and the policy publishes yearly request counts.
  • The API page spells out that the data must not be used for FCRA decisions.

What Gives Us Pause

  • The inconsistencies above, on financial fields, search history and unsourced audience claims.
  • The consumer facing pages we read do not carry the FCRA warning that appears on the API page.
  • The terms limit technical support to email, although the about page and site footers also give the phone line +1 (844) 405-2145. The terms disclaim accuracy, and no refund is offered after a billing date.
  • No company street address is given, and the policy does not address GDPR or California rights.

FAQs

How many free searches does NumLookup allow?

One phone number lookup per day, with no signup, according to the FAQ.

What do the paid plans cost?

$10, $20 or $50 per month in US dollars, for 40, 80 or 200 lookups, on the signup page we read.

Will the person I search be told?

The homepage says never, though the privacy policy says NumLookup keeps your search history.

May a landlord or employer rely on it?

No. NumLookup’s API page rules out employment and tenant screening, and the FCRA governs reports used for those decisions.

How can I take my details off NumLookup?

Use the phone or name tab of the opt-out form at numlookup.com/opt_out; EU residents can also cite GDPR rights.

Does a refund apply after renewal?

No. Per the signup page, cancelling before renewal avoids the next charge, but a charge already made is not refunded.

Where We Land on numlookup.com

NumLookup is a long registered, clearly priced reverse phone and people search site with a usable daily free search, a published opt-out route and monthly plans that stop when you cancel before renewal. Its weak points are the trust gaps listed above and an FCRA warning that sits on the API page rather than next to the consumer search box. Use it, if at all, to screen an unknown caller, confirm what it says elsewhere, and keep it away from decisions about jobs, housing, credit or insurance.
