How to name your Washington D.C. LLC
Naming a Washington D.C. LLC takes 4 steps: check name availability through the DLCP's CorpOnline system, confirm your name meets D.C. naming rules, check for trademark conflicts, and include the approved name in your Articles of Organization (Form DLC-1) when you file with the Department of Licensing and Consumer Protection.
General LLC naming rules
Every LLC in the United States — regardless of state — must follow a core set of naming rules. Your D.C. LLC name must include a required entity designator, must be distinguishable from other registered names, and cannot include terms that mislead the public about what your business does.
The required entity designator for a standard D.C. LLC is one of the following: "Limited Liability Company," "Limited Company," "LLC," "L.L.C.," "LC," or "L.C." The words "Limited" and "Company" may be abbreviated as "Ltd." and "Co." respectively. Your name must include one of these — no exceptions.
If you're forming a professional LLC — for licensed professions like law, medicine, or accounting — the name must include "Professional Limited Liability Company," "P.L.L.C.," or "PLLC" instead of the standard designator.
D.C.-specific naming rules
Washington D.C. adds a few requirements on top of the general rules. Your LLC name must be distinguishable on the DLCP's records from every other business entity already registered or reserved in the District — not just identical matches, but names that are confusingly similar.
D.C. law also prohibits names that imply a different entity type. You can't use "Corp.," "Inc.," or "Ltd. Partnership" in an LLC name because those terms suggest a corporation or limited partnership. Similarly, your name can't falsely imply a purpose your LLC isn't authorized to carry out under its Articles of Organization.
Certain words are restricted or require additional approval. Terms suggesting banking — like "bank," "trust," or "savings" — require authorization under D.C. banking law before you can use them. Names that imply government affiliation or suggest the business is a licensed insurer face similar restrictions. If your proposed name includes any regulated term, check with the relevant D.C. agency before filing.
How to search for a business name in D.C.
D.C. name availability is checked through the CorpOnline system, operated by the Department of Licensing and Consumer Protection. You'll need to create a free Access DC account before you can run a search — the search tool isn't available without logging in.
Once you're logged in, use the Business Filings Search or Business Entity Search function and enter your proposed name in the Entity Name field. The results show entity name, file number, entity type, status, and registered agent information. If an active entity with the same or a very similar name appears, that name isn't available — you'll need to choose something more distinguishable.
The D.C. name search catches conflicts with registered entities, but it doesn't check federal trademarks or trade names registered in other states. Run a separate trademark search before you commit to a name.
How to come up with a business name
A good business name is one you can actually use — available in D.C., clear to customers, and not already claimed as a trademark. Most entrepreneurs find it helps to start with 3 to 5 candidates rather than falling in love with one name before checking availability.
Think about how the name reads on a business card, in a web address, and in a search result. Short names are easier to remember and easier to spell. Avoid names that are too generic — "D.C. Business Services LLC" will be hard to distinguish from existing names and harder for customers to find online.
Check whether a matching domain name is available before you finalize anything. Your LLC name and your web address don't have to match exactly, but a close match makes it easier for customers to find you. A name that's available in D.C. but already taken as a .com is worth reconsidering.
Trademarks and service marks
The DLCP name search only tells you whether a name is available in D.C. It doesn't tell you whether someone else already owns a federal trademark on that name. Using a name that infringes on an existing trademark can mean a cease-and-desist letter or a forced name change after you've already filed — which is expensive and disruptive.
Search the USPTO Trademark Electronic Search System (TESS) before you finalize your name. Look for exact matches and similar-sounding names in the same industry. Trademark conflicts aren't limited to identical names — the USPTO considers whether marks are confusingly similar in sight, sound, or meaning within the same class of goods or services.
Also search Google, social media, and business directories for businesses using the same name in your industry. Trademark rights in the U.S. can arise from use alone — not just from federal registration. If a business has been using a name in commerce, they may have rights to it even without a USPTO registration. A trademark attorney can help you figure out whether a conflict is real before you commit.
How to register your D.C. LLC name
The primary way to secure your LLC name in D.C. is to include it in your Articles of Organization (Form DLC-1) when you file with the DLCP Corporations Division. Once the DLCP approves your filing, the name is registered to your LLC.
If you're not ready to file yet, you can optionally reserve your name before formation by submitting a name reservation filing to the Corporations Division. A reservation holds the name for 120 days while you prepare your formation documents.
If you want to run your business under a name that's different from your LLC's legal name, you can register a trade name with the DLCP. A trade name — sometimes called a DBA ("doing business as") — lets your LLC operate publicly under a different name without changing your legal entity name. The trade name must also be distinguishable from existing names on the DLCP's records.
Common naming mistakes to avoid
Most D.C. LLC name rejections come down to a handful of mistakes that are easy to avoid if you know what to look for. The DLCP will reject your Articles of Organization if the name doesn't meet requirements — which means a delay and a refiling.
Missing the LLC designator — forgetting to include "LLC," "L.L.C.," or another accepted abbreviation is the most common reason a filing gets rejected
Choosing a name too similar to an existing one — the DLCP requires distinguishability, not just uniqueness; a name that's one word off from an active entity will likely be rejected
Using corporate designators like "Inc." or "Corp." — these imply a corporation, not an LLC, and D.C. law prohibits names that misrepresent the entity type
Including restricted terms without approval — words like "bank," "insurance," or "engineering" may require regulatory authorization before you can use them in a D.C. business name
Skipping the trademark check — a name that clears the DLCP search can still infringe on a federal trademark, and getting it wrong can mean a forced name change after formation
FAQ
You search D.C. business name availability through the CorpOnline system operated by the Department of Licensing and Consumer Protection. Create a free Access DC account, log in to CorpOnline, and use the Business Entity Search to enter your proposed name. Results show whether an active entity with the same or a similar name is already registered in the District.
The CorpOnline search only covers D.C.-registered entities. Run a separate USPTO trademark search to check for federal trademark conflicts before you commit to a name.
Yes. Your D.C. LLC name must include a required entity designator — "LLC," "L.L.C.," "Limited Liability Company," or another accepted abbreviation. The name must be distinguishable from all other entities already registered with the DLCP. It can't include terms that imply a different entity type, falsely suggest a government affiliation, or use restricted words like "bank" without regulatory approval.
Yes. In Washington D.C., your LLC can operate under a trade name — sometimes called a DBA — that's different from its legal name. You register the trade name with the DLCP Corporations Division. The trade name must still be distinguishable from other names on the DLCP's records, and it doesn't replace your LLC's legal name for official filings.
Yes. You can reserve a D.C. LLC name for 120 days by submitting a name reservation filing to the DLCP Corporations Division before you file your Articles of Organization. This holds the name while you prepare your formation documents. Name reservation is optional — if you're ready to file, you can skip it and include the name directly in your Articles of Organization (Form DLC-1).
The most common mistakes are: leaving out the required LLC designator ("LLC" or "L.L.C."), choosing a name too similar to an existing D.C. entity, using corporate terms like "Inc." or "Corp." that imply a different entity type, and including restricted words like "bank" without regulatory approval. Skipping the USPTO trademark search is also a mistake — a name that clears the DLCP can still infringe on a federal trademark.
It depends on the processing time at the DLCP when you file. Standard processing times vary, and the DLCP may offer expedited options for an additional fee. Check the DLCP website for current processing times before you file. The name search and preparation steps you do beforehand don't add to the official processing window — those happen on your end before you submit Form DLC-1.
