Federal Firearms Licensees (FFLs) use the NICS system to determine whether a prospective buyer can buy firearms or explosives.

The NCIS handled over 100 million checks in the last decade, leading to over 700,000 denials.


Although Pipl is not a background check company, it offers data services to several companies. The Pipl query engine helps find deep web pages that cannot be found on regular search engines.

Different Types of Background Checks

A gun background check is appropriate when an individual tries to purchase a gun from a federally licensed gun dealer. The Bureau of Alcohol, Tobacco, and Firearms licenses all dealers. All gun dealers and retailers must check on the purchaser through the FBI. The buyer has to provide their ID and fill out a form known as ATF Form 4473, which collects personal information. The dealer can submit the information via phone or online and can get a response in a few minutes.

Business background checks allow you to learn about companies by performing a comprehensive search before working with them. A business check can determine if they have filed for bankruptcy, who has liens against their assets, and if they are a legally operating company. In addition, it will check for essential data and information such as:

  • Business licenses
  • OSHA violations
  • Civil and criminal litigation cases
  • Credit history or credit check
  • Liens and judgments
  • Securities and Exchange Commission (SEC) records (if a publicly-traded company)
  • Better Business Bureau complaints
  • Chamber of Commerce in the city
  • Consumer complaints
  • Products and services
  • Online Reputation
  • Legal status (e.g., legal registration as a partnership, corporation, sole proprietorship, etc.)
  • Industry
  • Major competitors
  • Criminal check or the owners or officers of the company

Date checkups (to learn more about the person you’re dating). This is another popular trend. Anyone can use an online service to do a reference lookup on a prospective mate. Truly, we can all make better dating decisions knowing our mate’s criminal, employment, and financial history.

Nanny background checks are critical in hiring nannies, caregivers, babysitters, etc. The types of data and information pulled together for this type of history check don’t differ. However, parents will scrutinize the information more closely because they are using it to hire someone to protect their child/children.

Open Source Intelligence (OSINT) Search – Increasingly, critical data and information about individuals are stored in open sources. For example, in social profiles, online discussion boards, the deep web, and more.

Self-checks. Proactive job seekers can use the resources below to get a copy of their reports. It is better to know what is in your report. That way, you’ll be prepared for questions from potential employers.

What is included in a typical report?

Most involve some combination of the following:

  • Identity Verification includes the individual’s first and last name, social security number, marital status, and former residence.
  • Criminal history – including criminal records, arrest records, police records, and court records. If you’re looking specifically for a police report, read the article on how to get a copy of a police report.
  • Financial / Credit History—including credit history, liens, and judgments. When a person deals with money or financial services, the company may pull a credit history report.
  • Employment History Verification includes checking work experience, resume validity, personal references, and more.
  • Verify education history and academic credentials, degrees, diplomas, professional certifications, and schools and universities attended.
  • Driving records and driving history or DMV records check help to determine if the candidate is a responsible driver, has outstanding tickets, has a valid driver’s license, etc.

Other information may be provided depending on the service provider and the details you need for each inquiry.

  • Social media search
  • Death record retrievals such as death certificates and obituary search
  • Marriage and divorce verification or confirmation
  • Miscellaneous public record retrieval
  • Professional license search
  • Real estate records, property ownership reports

Other key data points confirm membership in various organizations, political affiliations, ethnic profiles, and religions. However, these cannot be used when making a hiring decision.

In some cases, screening companies may go further than merely pulling reports. Additional steps may include a drug test and speaking with personal references. In cases where the person may be working with children, the company may conduct a sex offender registry search. Of course, if someone is applying for a position in the military, a military service history check will be necessary.

How Much Do Background Checks Cost?

The cost of reports and verification services varies widely. You will need to contact the provider directly to get pricing information. Usually, pricing will be either a subscription model (with monthly or annual charges) or fixed pricing. Some companies offer a “pay per report” option as well. Be sure to understand the cost and fees involved before purchasing. If you are working with a private eye, get a quote upfront for all payments.

Free Background Checks or Online Searches

Of course, while searching online for companies that provide public records, you will likely come across advertisements promoting the availability of free services or police record searches. Truly, some reports and data may be available for free in the form of public records. However, a true free check is likely not available or will likely be incomplete.

Some online detective software packages suggest investing just a tiny amount. Then, you can use their software and conduct unlimited searches for free. In reality, you do get unlimited access to their search tools. Unfortunately, unlimited access usually provides little more than free telephone number and address searches.

Our advice is to ignore the advertisements for free checks. Investing the money and working with one of the above companies is worthwhile if you need to learn about someone’s criminal history, driving record, or online activity.

Real Estate and Property Reports

Real Estate Reports provide basic information on properties, including residential real estate, commercial real estate, institutional real estate, community buildings, land, and much more.

Private investigators are often called upon to conduct research related to real estate, including residential properties, small businesses, commercial real estate, community buildings, and other structures. In many cases, Private investigators may be hired to find the information, such as part of a surveillance project, or they may need to gather it for their purposes. In such situations, detectives rely on a variety of information sources, such as:

  • Public records available at the county courthouse will show property details, ownership information, and other data.
  • Public records search available through the companies listed above (or others)
  • Search engines such as Google, Yahoo, and Bing can quickly access publicly available information, photos, videos, and more.
  • Online real estate and property information tools include, Trulia, or Zillow.


The Professional Background Screening Association (PBSA) is a non-profit trade organization representing companies that offer employment and screening services. The association promotes ethical business practices and compliance with the Fair Credit Reporting Act.

Presenting Information and Data to Clients

After retrieving the raw data on the subject, take the time to analyze the information and summarize the key information in the form of an investigative report. The private investigator’s job is to cull through the data and determine the relevant facts to the investigation. Once all relevant information and data are assembled, it should be presented in a simple and easy-to-understand format.

Provide detailed descriptions for various data points to help your clients understand the information, what it is, and why it is essential.

Also, don’t simply email or mail the report to your client. Try to present the information in person. That way, you can review the information, converse, answer any questions or concerns, and agree on what needs to happen next. Presenting what you found or uncovered in person is a professional touch that will go a long way toward earning your client’s trust and, potentially, their future business.

Questions and Comments

Please comment below if you have any questions about running background checks or the list of companies that provide the services.

  1. I’m a licensed and bonded investigator in South Carolina. I have contacted several search databases about signing up and their requirements are ridiculous. I am a small one man operation who is mobile 90% of the time. I have no need for an office nor do i desire the overhead costs. These companies are asking to come inspect my home before I’m allowed to sign up. I live in a loft and apparently I don’t qualify because I don’t have a separate locking room with filing cabinets and a shredder. My state credentials aren’t good enough and the fact that I don’t have the operating capital for a fancy office apparently makes me less of an investigator. It’s a joke what these services are allowed to do.

    • I am a licensed and bonded investigator in South Carolina as well. I have a home office and have been through several inspections. It has nothing to do with your state credentials, the expectations from the data providers are that the private information that you obtain will be out of reach of unlicensed individuals and will be properly handled, meaning filed or shredded. Your license is what allows you the access. There are a few providers out there that will not do an inspection but in return will limit the info they provide.

      • I will not agree with your answer. I’m using one site that doesn’t do inspection but still provides me with very accurate information about my targets. It’s not some kind of auto-generated report (i don’t consider those kinds of reports much relevant) but rather they have some team of experts that find the most relevant information about the person you’re looking for…

  2. I need a detective to find the papers
    Of a devorce case in Torino court and and i need the full details of the case.

    Best Regards
