Check your business name availability free at the PA Department of State Business Entity Search portal. Use the “Contains” search option and exclude LLC designators, punctuation, and filler words to find conflicting names.
Step 1: Go to the PA Business Entity Search Portal
The Pennsylvania Department of State maintains a free, public Business Entity Search at pa-dos.com. This is your first stop — it’s fast, official, and it’ll show you exactly what names are already taken.
Head to the search portal, and you’ll see a simple form. You can search by entity name, by registered agent, or by filing number. For checking name availability, you want the “Entity Name” field.
Step 2: Search Smart — Use “Contains” and Drop the Extras
This step separates the pros from the rookies. The search has two options: “Starts With” and “Contains.” Use “Contains.” If you search “Starts With,” you’ll miss similar names that start differently. “Contains” catches everything. Before you hit search, strip out anything that won’t legally matter:
Step 3: Read the Results — What “Taken” Really Means
Your search results show every registered entity with a similar name. But “taken” doesn’t always mean it’s off-limits to you.
Pennsylvania law requires your LLC name be “distinguishable upon the records” from existing names. That’s the legal standard. You’re not just checking for identical matches — you’re checking if a name is too close to another one.
The tricky part: you can’t just add words and call it different. Courts know the tricks.
The Distinguishability Rules (What Actually Works and What Doesn’t)
| What You Try | Does It Work? | Why |
|---|---|---|
| Add LLC or Inc to the end | No | Designators are required anyway — they don’t make names distinguishable |
| Add a filler word (the, a, and) | No | PA specifically rejects filler words as distinguishing |
| Make it plural (add ‘s’) | No | Minor changes like pluralization don’t count |
| Add a city name (Pittsburgh, Philly) | No | Geographic words don’t automatically distinguish names |
| Use different spelling or abbreviation | Maybe | Only if it’s substantially different phonetically and visually |
| Completely different name | Yes | Obviously. Pick a different core name entirely |
| Company operates in different industry | Maybe | Business category helps but doesn’t guarantee approval |
Step 4: Check Dissolved and Inactive Companies Too
Here’s what most guides miss: a dissolved or inactive business doesn’t always free up the name.
If an LLC is dissolved, it’s still on the records. If you try to file with that exact name, Pennsylvania may reject it. The dissolved entity holds a claim on the name for a period after dissolution.
Your search results show status — look for “Active,” “Dissolved,” “Inactive,” or “Withdrawn.” An inactive or dissolved name can still block yours if it’s too similar.
What to Do If Your Name Is Taken (Your Real Options)
So the search came back and your dream name is already taken. Don’t panic. You have actual options. Option 1: File a Name Reservation. Pay $70 to the PA DOS and they’ll hold the name for 120 days while you decide on next steps or wait for a similar business to dissolve. Option 2: Tweak the name completely. Not just add a word — actually pick a new core name. The search results show you what’s taken. Pick something genuinely different. Option 3: Verify it’s a real competitor. A dissolved or inactive company with your name might be worth watching — it could become available. Your name reservation buys you time.
PA LLC Requirements — Don’t Forget These
Fictitious Name (DBA) — Separate But Important
Your LLC name and your business’s “doing business as” name are different things.
You might file an LLC called “Smith Business Solutions LLC” but operate as “SBS Consulting.” The DBA is what your customers see. It’s registered separately with the PA DOS. Run a separate search for your DBA to make sure no one else is using it in your county.
Don’t skip this step. A DBA search protects your brand locally.
Should You Check Federal Trademark Too?
The PA Business Entity Search only covers Pennsylvania. If you’re serious about protecting your brand nationally, run a federal trademark search through the USPTO (tess.uspto.gov).
Even if your name is available in PA, someone could hold a federal trademark for the same or similar name. That’s a real risk if you plan to sell across state lines or build a strong brand.
Registering your Pennsylvania LLC name doesn’t give you federal trademark protection. They’re completely separate.
Frequently Asked Questions
Probably not immediately. Dissolved entities still hold a claim on their names for a period. Wait or file a name reservation and contact the PA DOS to ask about that specific name.
No. Adding a different designator (Inc vs. LLC vs. Corp) doesn’t make a name distinguishable. You have to change the core name itself.
$70. It holds your name for 120 days while you finalize your business plan or wait for a similar entity to dissolve.
No. PA Business Entity Search checks state registration only. Federal trademark (USPTO) is separate and national. Check both if you want full protection.
Yes. Your LLC name is registered with the state. Your DBA (doing business as) is what customers see and is registered at the county level. You can have any DBA, as long as no one in your county is using it.
Contact them directly. The search tool is helpful but not the final word. The PA DOS secretary makes the final call. A brief written request for clarification sometimes helps.
