Different Types of Background Checks

A gun background check is used when an individual tries to purchase a gun from a federally licensed gun dealer. The Bureau of Alcohol, Tobacco, and Firearms is responsible for licensing all dealers. All dealers are required to run a 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 the phone or online and can get a response in a few minutes.

Nanny background checks can be used in making hiring decisions for nannies, caregivers, babysitters, etc. The types of data and information pulled together for this type of history check don’t differ from any other. However, the information is scrutinized more closely, because it will be used to hire someone to protect one’s children. Read more.

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

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.

Business background checks allow you to learn about companies before doing work with them by performing a comprehensive search. A business check can be used to determine if they have filed for bankruptcy, who has liens against their assets, and if they are a legally operating company. In addition, business licenses, OSHA violations, litigation, credit check, liens and judgments, SEC records (if a publicly-traded company), Better Business Bureau, Chamber of Commerce in the city, consumer complaints, products and services, reputation, legal status, industry, major competitor and finally a criminal check or the owners or officers of the company.

What is included in a typical report?

Most involve some combination of the following:

  • Identity Verification including the individual’s first and last name, social security number, marital status, former residences.
  • Criminal history – including criminal record, 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. In cases where the person may deal 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, and diplomas, professional certifications, schools and universities attended, etc..
  • 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 amount of detail you need with 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 such things as membership in various organizations, political affiliations, ethnic profile, and religion. However, these cannot be used in 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. In general, you will need to contact the provider directly to get pricing information. In most cases, 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 fees.

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 that you can invest just a small amount. Then, you can use their software and then conduct unlimited searches for free. In reality, you do get unlimited access to their search tools. Unfortunately, that unlimited access usually provides you with little more than free telephone number and address searches.

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

Real Estate and Property Reports

Real Estate Reports provide basic information on properties including residential real estate, commercial real estate, institutional, 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 the information for their own purposes. In such situations, detectives rely on a variety of information sources such as:

  • Public records available at the county courthouse that will show property details, ownership information, and other data
  • Public records search available through the companies listed above (or others)
  • Additionally, search engines such as Google, Yahoo, and Bing can provide quick access to publicly available information, photos, videos, and more.
  • Online real estate and property information tools such as, 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. It is the private investigator’s job to cull through the data and determine the facts that are relevant to the investigation. Ultimately, once all of the relevant information and data is assembled, it should be presented in a format that is simple and easy to understand.

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

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, have a conversation, 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.

  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
