Washington D.C. LLC Name Search & Naming Rules (2026)
Your D.C. LLC name has to clear the DLCP's database before you can file. Here's how to search it free and when the optional reservation is worth its cost.
Search availability free with the DLCP's business entity search through CorpOnline. Your name must be distinguishable from every existing D.C. entity and contain "Limited Liability Company," "LLC," or "L.L.C." D.C. does not require a separate name reservation as part of LLC formation — your name is approved automatically when your Articles of Organization are approved. A standalone reservation is available for $50, valid 120 days, if you're not ready to file yet.

D.C. LLC Naming Rules
- Required designator: the name must contain "Limited Liability Company" or an abbreviation — "LLC" or "L.L.C."
- Distinguishable on the record: it can't match or closely shadow any entity registered with the DLCP.
- Restricted words: terms implying banking, insurance, or government affiliation require proper authorization.
Check the domain before you commit: at $99 a filing, a name mistake isn't the expensive part of forming in D.C. — but a branding one is. Before you fall for a name, confirm the .com (or a clean variant) is free and grab the matching social handles. The state check takes a minute; whether your real brand is available online is what actually matters for your long-term business.

How to Search D.C. Name Availability (Free)
Open the DLCP's business entity search via CorpOnline
Free, searches every LLC, corporation, and registered entity on file in D.C.
Search core words without the designator
Search "Capitol Hill Consulting" rather than "Capitol Hill Consulting LLC" to surface the widest set of potential conflicts.
Check close variants
Minor spelling, spacing, or punctuation differences don't reliably make a name distinguishable — when in doubt, contact the DLCP to confirm.
File once your search is clean
Proceed directly to the Articles of Organization — your name is claimed at no extra cost.
The Optional Reservation
If you're not ready to file yet, D.C. offers a standalone name reservation for $50, valid 120 days, through the DLCP. But since claiming the name is free when it's part of your actual Articles filing, most founders ready to move within a few weeks can skip the reservation entirely.
Ahmad Adil's Take: D.C.'s naming process is genuinely simple, and not having to pay a separate reservation fee is a real, small convenience. My advice on names is the same everywhere: don't skip the domain check just because the district process is simple. A $99 formation cost is nothing compared to redoing your branding after you've already built a following around a name that turns out not to work online.
