District Of Columbia Business Name Search – (Apr. 2026) Guide

Your first task before filing your Articles of Organization with the District of Columbia Department of Licensing and Consumer Protection (DLCP) is to perform a DC Business Name Search.

Completing a District of Columbia Business Name Search ensures that your desired LLC name is unique and distinguishable compared to existing business names before officially forming your Limited Liability Company (LLC). Your Articles of Organization will be rejected if your LLC name is unavailable or fails to follow the district’s naming rules.

In this article, I will discuss how to perform the Business Name Search, how to correctly interpret the results, and ways to make sure your name is unique and distinguishable according to district naming laws.

The District Of Columbia Business Name Search Overview

Under the DC Code § 29–103.01, your Washington DC LLC name must be unique and distinguishable compared to existing business names before submitting your Articles of Organization to the District. Your filing will NOT be accepted if your desired name is already in use by an existing business.

Therefore, you can use the Business Entity Search tool to compare your desired LLC name against existing businesses registered in the District of Columbia. This allows you to determine if your name is available or already in use.

How To Perform A District Of Columbia LLC Name Search

1. Access The Portal And Enter Your Desired LLC Name

Navigate to the main DLCP’s Entity Search portal to begin. Then, enter your desired LLC name in the provided search box and click “Search.”

The system automatically selects the “Contains” search option. Make sure you keep this enabled so you can see all potentially similar business names.

Keep these tips in mind when performing your search:

• Don’t add a designator when performing your search (“LLC”, “L.L.C.”, “Limited Liability Company”, etc.).
• Leave out commas, periods, and apostrophes, etc.
• Search using uppercase or lowercase letters.

I recommend entering just the main words of your desired LLC name when performing your business search by name.

Example: Your desired name is “John Doe LLC.”

• First, search for “John Doe.”
• Then, search for “John.”

This should catch all “potentially similar” results.

2. Check Your Search Results

The system should display a table of results under your search bar once you’ve performed your search.

You’ll see several different columns. However, you only need to focus on the “Entity Name/Trade Name” column to interpret your search results. I’ve guided you through how to do this below.

Interpreting Your District Of Columbia Business Name Search Results

Your Washington DC business name search has four possible result outcomes. I’ve discussed each one below, including how to interpret them, so you can create a unique and distinguishable business name.

1. The Search Results Show Names That Are Not Too Similar To Yours

If your search results show names that are not too similar, your desired LLC name is likely available to use.

Example: Your desired LLC name is “Hanna Place LLC.”

• Your result shows “4620 HANNA PLACE LLC” or “5045 HANNA PLACE LLC.”
• Your LLC name is likely still available.

2. The Search Returns No Results

If your results return “No Search Results Found,” your desired LLC is unique and available to use. When this happens, run another search using part of your desired name to be sure.

Example: You searched “Anna Bakery.”

• Your search returned no results.
• You run more searches using “Anna” or “Bakery” to be sure.

3. Your Exact LLC Name Appears In The Search Results

If your search results returned your exact business name in the search results, your desired name is NOT available to use. In this case, an existing business entity is already using it.

Read my guide on how to make your desired LLC name distinguishable in the sections below. You should do this before trying to change your desired name.

4. A Name That Is Very Similar To Yours Appears In The Results

Your desired LLC name may or may not be available to use if your search results show a very similar LLC name.

Generally speaking, the DLCP is flexible regarding name distinguishability, meaning that similar names are sometimes allowed. However, names that are too similar can still confuse or be rejected. Because of this, I advise proceeding carefully or choosing a more unique variation.

Example: Your desired name is “Decatur Street.”

• The name “1202 Decatur Street” appears in your search results.
• Your name may be available.

I advise either contacting the DLCP directly for confirmation or choosing a clearly unique name by following my guidelines below.

5. Do You Need To Reserve Your LLC Name?

You do NOT need to reserve your desired LLC name before registering it with the DLCP under the DC Code § 29–103.03.

However, you can reserve the name so no one else can use it if you’re NOT ready to form your LLC. You must pay a $50 name reservation fee to get your name reserved for 120 days.

Name Requirements For District Of Columbia LLCs

You must be aware of the district’s naming rules and regulations set under DC Code § 29–103.02 if you want to choose a unique and acceptable business name.

1. Use Mandatory Designators

Your desired business name must contain one of the following name designators (endings):

• LLC.
• L.L.C.
• L.C.
• LC.
• Limited Liability Company.
• Limited.

Furthermore, you need to use one of these designators if you open a professional LLC:

• P.L.L.C.
• PLLC.

2. Avoid Prohibited Designators

Your desired LLC name must NOT sound like a Washington DC Corporation or another business entity besides an LLC. Do NOT use the following designators or abbreviations of them in your desired LLC name:

• Inc.
• Corp.
• Incorporated.
• Corporation.
• Non-profit.
• Non-Profit Corporation.

3. Avoid Prohibited Words

You can NOT use words or abbreviations restricted by law in your LLC name under DC Code § 29–103.01 (e) and (f). These include:

• The words “bank”, “banking”, “credit union”, “insurance”, or similar words without the approval of the Mayor.
• The name of any department, agency, or instrumentality of the United States or the District of Columbia that may mislead the public or cause confusion.

Example: You can NOT use “I.R.S.” in your name unless you’re connected to the Internal Revenue Service.

4. Always Use The English Alphabet In Your LLC Name

Under DC Regulation 17-709.1, you must register the English translation of your name if your desired LLC name is in a foreign language. In other words, your DC Articles of Organization must use the English translation.

Example: Your desired LLC name is in Korean. You should use the English (Roman) characters instead, such as: “Han River Trading LLC.“

How To Make Your DC LLC Name Unique

As I’ve stated above, the DLCP is quite flexible when it comes to creating a distinguishable business name. Even so, names that are too similar may still confuse and be rejected by the district.

Therefore, I recommend choosing a clearly unique name, even if a similar one may be allowed. You can contact the DLCP using the information above if you’re unsure.

1. Don’t Just Change Designators

Don’t just change your designator (name ending) if you find a very similar LLC name in your search results. Remember, differences in designators do NOT create distinguishability. An example would be changing your designator from “LLC” to “L.L.C.” Instead of this, choose a new, unique name that still shows your true business purpose.

Example: Your desired LLC name is “Evergreen Solar Solutions LLC.” You could use:

• “Evergreen Renewable Energy LLC.”
• “Evergreen Clean Power LLC.”

2. Adding Filler Words Can Create Distinguishability

You can create distinguishability by adding non-meaningful or filler words (the, a, an, and, &, of, or).

Example: Your desired LLC name is “Blue Horizon Consulting LLC.”

If it’s taken, you can add these filler words to make it distinguishable:

• “The Blue Horizon Consulting LLC.”
• “A Blue Horizon Consultant Inc.”
• “Blue and Horizon Consulting L.L.C.”

3. Plural Words And Possessive Words Create Distinguishability

You can create distinguishability by adding an “s” to make a word plural or possessive.

Example: Your desired LLC name is “Silver Oak Designs LLC,” but your search results show that it’s taken.

You could make it distinguishable by changing it to:

• “Silver’s Oaks Design LLC.”
• “Silver Oaks Design LLC.”

4. Numerals And Spelled Out Numbers Create Distinguishability

Create a distinguishable business name by using numerals (like 5 or 101) instead of spelling out the number (like “five” or “one hundred and one”).

Example: Your desired LLC name, “12 River Solutions LLC,” is taken. You could make it distinguishable with these small changes:

• “Twelve River Solutions LLC.”
• “12 Rivers Solution Inc.”
• “Twelve Rivers Solutions, L.L.C.”

Roman numerals can also create distinguishability. Using them instead of standard numbers is considered to make a “valid difference” to your LLC name in the district.

Example: The name “Rock 2 Earth LLC” is unavailable.

• Instead, you could register “Rock II Earth LLC.”
• This name is considered distinguishable as it contains Roman numerals instead.

5. Punctuation And Special Characters Create Distinguishability

Lastly, you can use punctuation and special characters to create distinguishability. However, I advise doing so with caution. These characters are ignored in the Business Entity Search, which can still cause public confusion.

Example: Your desired name is “Girl$ Salon LLC.”

It may still be allowed even if these names exist in the district:

• “Girls * Salon Inc.”
• “Girl’s Salon LLC.”
• “Girls “Salon” L.L.C.”
• “Girls-Salon Inc.”

What If My Washington DC Business Name Is Rejected?

You don’t need to worry if you submit your District of Columbia Articles of Organization and your business name isn’t available. The district will notify you and explain why your filing was rejected.

In this case, you can refile using a modified version of your LLC name or choose a completely different name.
