Private Investigator License Addresses: What CA, TX, FL, and NY Require and What Becomes Public

California: the address of record and the physical address

In California, the license that lets a business sell investigative services is called a Private Investigator license. The BSIS application packet (revised October 2025) says a separate company application must be filed for each entity, and the business needs a qualified manager who has passed the bureau’s exam.

The application asks for a business address by number and street. The packet sets the rule for P.O. boxes in these words: “A post office box or mailbox service may not be used as the address of record unless mail delivery to the physical location of the business is not possible, or the principal place of business is located in the applicant/licensee’s personal residence.” If you do list one, the packet says you “should provide an explanation for doing so with the application and provide the actual physical location/address of the business in the accompanying explanation.”

So a mailbox service address can be the address of record in two cases, and both still require the physical location. The bureau’s FAQ adds that “if providing a PO Box as the AOR, you must provide the Bureau with your residence address.” The business name request form in the same packet says “The Bureau must maintain a physical address of record on file at all times.” It also gives home-based investigators an option: “If you are operating out of your residence and wish to keep your physical address confidential from public record, please submit a written request and attach it with this form.”

• Where you can work: the bureau’s FAQ says “A licensee may only conduct business at the location shown in the Bureau’s records unless he or she obtains a branch office certificate.”
• Branch offices: the branch office form says “A branch office registration is required for each additional location, separate of the principal place of business,” and lists a $99.00 application fee.
• Advertising: the FAQ says the business name, business addresses or telephone number, and license number must appear on business cards, stationery, paid advertisements in any media form, and other advertising “as they appear in the Bureau’s records.”
• Moving: the company address change form says a change of address must be submitted within 30 days. The same form says a P.O. box or mailbox service address of record must come with the physical address of the business.

The advertising rule matters for an investigator who wants clients to see a business address. The FAQ asks for the business addresses or telephone number, so an ad can carry a phone number alone. If you show an address, it is meant to match the bureau’s records. If you plan to show clients a different address from the one you file, ask the bureau first how it applies the advertising rule to your case.

What California publishes about investigators

The BSIS forms say that “the names and addresses of persons possessing a license or registration may be disclosed by the Department unless otherwise specifically exempt from disclosure under the law.” The Department of Consumer Affairs puts this into practice with a public licensee file. Its record layout lists a column called “Public Address of Record,” along with city, county, state, ZIP code, license status, and dates. The department says the data “is refreshed automatically at the beginning of each month.”

We downloaded the BSIS file posted on October 1, 2026 and counted the current private investigator records on October 11, 2026. We counted rows whose address lines contain “PO Box” or “Post Office Box” in common spellings. A private mailbox address written as a street address with a suite number would not be caught by this count, so the real number of mail-only addresses could be higher.

Two points stand out. About one in five current private investigator licenses uses a P.O. box in the public address of record. The bureau allows that in two cases, when mail cannot be delivered to the business or when the business is run from home, and the file does not say which case applies to a given license. The second point is that the file also lists individuals. Qualified manager certificates are held by people, and the file gives each of them an address of record, so the address you give the bureau for yourself can be public as well.

Of the 6,076 current licenses, 390 list a state other than California in the address of record, and 10 have no state. We did not check whether those businesses also keep a California location.

Texas: a physical address for records, and individual licenses tied to a company

Texas licenses investigation businesses under Occupations Code chapter 1702. Section 1702.103 sets the company classes, starting with “Class A: investigations company license, covering operations of an investigations company.” Section 1702.110 says the company application must include “the full name and business address of the applicant,” and for an entity, “the full name and residence address of each partner, officer who oversees the security-related aspects of the business, and director of the applicant.”

Texas writes a physical address rule into the statute in two places. Section 1702.110(b) says “An applicant for a company license as a security services contractor shall maintain a physical address within this state and provide that address to the department.” That subsection names security services contractors. Section 1702.127(d) is written for any company license holder, which includes investigations companies: “A company license holder shall maintain records required under this chapter at a physical address within this state and provide that address to the department.”

The individual side works differently from California. Section 1702.221 says that to perform a regulated activity, an individual must hold the proper individual license and “be employed by a company license holder.” A private investigator is on the list, and so is “an owner who owns at least a 51 percent interest in a company license holder.” Section 1702.221(c) adds that an individual who performs more than one service that requires an individual license “must obtain an individual license for each service.” Because section 1702.101 bars acting as an investigations company without the company license, a solo investigator who owns the business needs that company license, and may also need an individual private investigator license for the investigative work itself. Ask the Private Security Program which individual licenses apply to your role.

• Branch offices: section 1702.002 defines a branch office as an office “identified to the public as a place from which business is conducted, solicited, or advertised” at a place other than the principal place of business in department records. Section 1702.129 requires written notice within 14 days after a branch office is established, closed, or changes address.
• Posting: section 1702.128 requires the company license to be posted in the principal place of business and in each branch office.
• Advertising: section 1702.131 says an advertisement “must contain the company license holder’s company name and address as stated in department records.”
• Home address: section 1702.085 says department records on the home address, home telephone number, driver’s license number, or Social Security number of an applicant or license holder “are confidential and are not subject to mandatory disclosure” under the Texas Public Information Act.

We could not load the Department of Public Safety’s website from our connection on October 11, 2026, so we did not review its current application forms, its rules on P.O. boxes, or what its online license search displays. The points above come from the statute.

Florida: one physical location per agency license

Florida licenses investigators under chapter 493 of the Florida Statutes, through the Department of Agriculture and Consumer Services. Section 493.6201 says a business that works as a private investigative agency “shall have a Class “A” license,” and adds: “A Class “A” license is valid for only one location.” Each branch office needs a Class “AA” license. Any individual who performs the services of a private investigator needs a Class “C” license, and Class “C” licensees “shall own or be an employee of” a Class “A” agency or a branch office.

Florida states the office rule plainly. Section 493.6106(2) says “Each agency shall have a minimum of one physical location within this state from which the normal business of the agency is conducted, and this location shall be considered the primary office for that agency in this state.” The agency application asks for “The street address, mailing address, and telephone numbers of the principal location at which business is to be conducted in this state,” and the same for each branch office.

The license is tied to that place. Section 493.6106(2) requires notice within 10 days when an agency or branch changes its physical location, and the agency license has to be posted “in a conspicuous place at the licensed physical location in this state where the business is conducted.” Statutory fee caps are $450 for a Class “A” license, $125 for a branch office license, and $75 for a Class “C” license.

The department’s licensee search page says “Individual address and phone information for private investigators and recovery agents is restricted from public record in accordance with Section 493.6122, F.S.” Agencies are searched with a separate tool. We could not load the agency and individual search screens at licensing.fdacs.gov from our connection on October 11, 2026, so we did not confirm which agency fields the search displays.

New York: no P.O. box as the business address

New York licenses private investigators under Article 7 of the General Business Law, through the Department of State. Section 72 asks the application to state where the principal place of business and each office or branch office will be located. The Department of State’s application form (DOS-0075, revised June 2024) puts it this way: “All applicants must list the address where they will be conducting business. The exclusive use of a post office box number as a business address is prohibited.”

The form has two address blocks. The applicant’s residence address asks for a street address and notes “P.O. Box may be added to ensure delivery.” The principal office address asks for a street address marked “(Required).” A P.O. box can sit next to a street address. It cannot replace it.

In New York the license is held by people as well as the firm. The form says that in a partnership all partners must be licensed, and in a corporation the officers, holders of 10 percent or more of the stock, and other principals each file an application. For an LLC, at least one member or manager must meet the experience and exam requirements and be licensed to conduct business under the firm’s name. The fee is $400 for an individual license and $500 for a corporate or business license, plus the same amount for each branch office, for a two-year term.

• Branch offices: the branch office form (DOS-1542, revised February 2023) says “The use of a post office box number as a business address is prohibited” and “Branch office licenses are mailed to the branch office address.” Each branch application needs a $10,000 surety bond.
• Trade names: a sole owner using a name other than their own name files the name with the county clerk of the county in which the business is located, according to the application form.
• Public lookup: the Department of State’s licensee search says “Please note that information pertaining to residence addresses is not included on this database.” It adds that private investigators “can only be searched by business name or UID#” and that “Individual qualifying officers are NOT displayed and cannot be searched.”

We ran a business name search on October 11, 2026. The results list shows an ID number, name, business name, city, license type, and expiration date, and each licensee’s detail page adds the business address and county. So the business address you file for a New York investigation firm can be read by anyone who searches its name.

Working from home as an investigator

Many investigators start alone and work from home. The four states handle that differently, and the difference is mostly about what ends up public.

A home office can also run into local zoning or business license rules, which sit outside the state license. We cover the local layer in our guide to business license rules for virtual addresses, and the address choices for a one-person business in our guide to sole proprietor business addresses.

Ads, branches, and the address clients see

An investigator’s address does more work than most, because it appears on business cards and ads and has to agree with the license file. In California, Florida, and New York, the business location on the license is meant to be a real place where you do the work: California through its physical address of record, Florida through its physical location rule, and New York through its address where you will conduct business. A mail-only address, including a virtual office address, does not fit that line in those three states. Texas asks for a business address on the application and requires records to be kept at a physical address in Texas, and we did not review its forms on whether a mail-only address can be the business address.

A mailing address is a different line. Florida’s application asks for a mailing address next to the street address. California lets a home-based investigator use a mailbox service as the address of record, as long as the bureau has the physical address. New York lets you add a P.O. box to a street address so mail reaches you. If you use a separate mailing address, put it only in the lines that ask for one, and keep the physical location on file where the form requires it.

Plan branch offices before you advertise them. California requires a branch office certificate for each additional location, Florida a Class “AA” license for each branch office, and New York a branch office application. Texas treats an office identified to the public as a place of business, other than the principal place of business, as a branch office that requires notice. A second address in your ads that is not in the agency’s records can conflict with the advertising rules in California and Texas.

Before you list any address on a license form, you can check how it is classified with our free address checker. It shows whether USPS data lists the address as residential or commercial, and separately whether it is listed as a commercial mail receiving agency (CMRA). That can help you decide which line it belongs on.
