PA Entity Searches & Naming Your Pennsylvania LLC

Whether you’re searching for the right Pennsylvania business name or registering your LLC with the PA Department of State, we can help. We’ve got all the information you need on Pennsylvania business entity search, LLC naming rules, fictitious names and registering your business.

PA Corporation Search

Before you register your business, you need to confirm that there's not already a registered Pennsylvania LLC that has your desired business name. This requires a search of the PA Secretary of State website, referred to in Pennsylvania as the Department of State. The PA DOS has a business search tool where you can easily look up PA LLCs and corporations by name and other details. A PA business name search verifies that your name is available for you to use and not taken by another PA entity.

If the business name is already used, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

Pennsylvania Secretary of State Rules for Business Names

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Pennsylvania Department of State naming rules. These do vary from state to state — we’ve got general naming rules below, as well as naming rules specific to LLC businesses formed in PA.

General Business Name Availability Rules

These rules typically apply to all LLCs, no matter what state they are formed in. You will need to pay attention to these rules as they will influence the name you choose for your Pennsylvania LLC.

Your LLC Business Name Must Be Unique

The business name you have chosen cannot be used by any other LLC or corporation in the state of Pennsylvania. This is why you should check business name availability on the PA DOS website.

Your LLC Business Name Must Not Be Confusable with Another Business Name

It’s not enough for your PA LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in Pennsylvania. For example, you cannot use the following factors to say your name is different from the name of another business:

  • Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., Ltd., LLC, etc.
  • Definite articles like “A,” “And,” “An,” “&,” “The,” etc.
  • The singular, plural or possessive forms of a word
  • Abbreviations, punctuation, symbols, fonts, typefaces, etc.
Your LLC Business Name Must Contain Certain Words

All LLCs must have the words “Limited Liability Company,” “L.L.C.” or “LLC” in their name. These words should normally come at the end of the name.

Your LLC Business Name May Have Other General Restrictions

Most states will not allow you to form LLCs with names that:

  • Are very similar to the name of a federal or PA agency or organization (e.g., FBI, FDA, Pennsylvania Department of Revenue, Pennsylvania Police, Treasury, etc.)
  • Suggest affiliation with a federal or state agency or organization
  • Use the term “Olympic” or any terms that are trademarks of the Olympic organization
  • Imply a purpose that it would be illegal for your business to carry out

Specific Pennsylvania Business Name Availability Rules

In addition to the general rules listed above, the Pennsylvania Department of State has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your PA business appropriately.

There are certain prohibited and restricted words that have limitations on how they can be used in a Pennsylvania LLC name. These include:

  • "bank," ‘‘banking," ‘‘banker," ‘‘trust," ‘‘college," ‘‘university," ‘‘seminary," ‘‘certified public accountant," ‘‘public accountant," ‘‘architect," ‘‘architecture," ‘‘engineer," "engineering," ‘‘surveyor," ‘‘surveying," ‘‘pharmacist," ‘‘druggist," ‘‘apothecary," ‘‘drug store," ‘‘pharmacy," ‘‘drugs," ‘‘medicine store," ‘‘medicines," ‘‘drug shop," ‘‘pharmaceutical," ‘‘homeopathic," ‘‘homeopathy," “‘annuity," ‘‘assurance," ‘‘beneficial," ‘‘bond," ‘‘casualty," ‘‘endowment," ‘‘fidelity," ‘‘fraternal," ‘‘guaranty," ‘‘indemnity," ‘‘insurance," ‘‘insurer," ‘‘reassurance," ‘‘reinsurance," ‘‘surety," ‘‘title" ‘‘mutual," or “electricity or gas utilities”

Pennsylvania LLC Fictitious Names

You might choose to do business under a different name from your legal LLC name. In Pennsylvania, this is known as a “Fictitious Name.” You might choose to use a different name from your PA formal LLC name for a variety of reasons.

For example, your LLC might be called Pennsylvania Sports and Leisure Holding Company LLC and you have a chain called Daper’s Hockey Gear. You should file a fictitious name to let the Pennsylvania Department of State know. In Pennsylvania, you do that through a Fictitious Name Registration form [DSCB:54-311], or you can have Incfile do it on your behalf through our Assumed Business Name service.

Register Your Business Name with the Pennsylvania Department of State

Once you’ve searched for your Pennsylvania business name, checked availability, followed the naming rules and decided whether you need a fictitious name, you can register your PA LLC name. There are a couple of ways to do this:


If you don’t want to form your Pennsylvania LLC right now, you can reserve the business name. You will need to complete a form and file it with the PA DOS. You do not need to reserve a name if you are forming your business right away.


If you’re ready to start your Pennsylvania LLC, you can file your Certificate of Formation with the Pennsylvania Department of State, or let Incfile take care of it for you.
