Searching for an available LLC name in Maryland is a required step before submitting your Articles of Organization to the Maryland State Department of Assessments and Taxation (SDAT). The SDAT maintains a real-time database of all registered business entities, and you can search it for free at any time. A search result showing no conflicts means your chosen name is not currently in use, but it does not guarantee approval — SDAT reviewers also apply distinguishability standards and naming rules that a database search alone cannot predict. The database shows active businesses, dissolved entities, and reserved names, so a name that appears available could still be flagged if it is too similar to an existing name under Maryland's distinguishability test. Always verify spelling variations and abbreviations before filing.
Step-by-step: using the Maryland State Department of Assessments and Taxation (SDAT) name search
- 1. Navigate to the Maryland SDAT Business Express entity search portal at https://egov.maryland.gov/BusinessExpress/EntitySearch.
- 2. In the 'Entity Name' field, type your desired LLC name — you can search a full name or a keyword; leave the entity type filter set to 'All' for the broadest results.
- 3. Review all returned results carefully, including businesses with similar spellings, abbreviations, or word order variations that could be considered confusingly similar under Maryland law.
- 4. Click any individual result to view the entity's status (Active, Forfeited, Dissolved) and confirm whether a name conflict is a genuine concern or involves an inactive business.
- 5. Repeat the search using common abbreviations, alternate spellings, and synonyms of your proposed name to ensure no similar entity would prevent your registration from being approved.

Maryland LLC naming rules
- The name must contain the words 'Limited Liability Company,' or one of the abbreviations 'L.L.C.' or 'LLC' — this designator is mandatory under Maryland Code, Corporations and Associations Article § 4A-204.
- The name must be distinguishable upon the records of SDAT from any other business entity name already registered or reserved in Maryland, including corporations, LLCs, and limited partnerships.
- The name cannot contain language that implies the LLC is organized for a purpose other than what is stated in its Articles of Organization.
- Words suggesting government affiliation — such as 'State,' 'Federal,' 'United States,' 'National,' or 'Municipal' — are prohibited unless the entity actually has such an affiliation.
- Restricted professional terms including 'Bank,' 'Trust,' 'Insurance,' 'Savings,' 'Surety,' and similar financial-industry terms require prior written approval from the applicable Maryland regulatory agency before SDAT will accept the name.
- Terms such as 'University,' 'College,' 'School,' or 'Institute' may require approval from the Maryland Higher Education Commission if they imply a degree-granting institution.
- The name may not include obscene, profane, or language that a reasonable person would find offensive under Maryland public policy standards.
- Punctuation and special characters are generally ignored during SDAT's distinguishability review, so 'ABC & Co LLC' and 'ABC and Co LLC' may be treated as the same name.
Restricted words in Maryland LLC names
The following words require special approval from a state agency before you can use them in your Maryland LLC name:
- Bank / Banking / Banker — requires Maryland Commissioner of Financial Regulation approval
- Trust / Trust Company — requires Maryland Commissioner of Financial Regulation approval
- Insurance / Insurer / Assurance — requires Maryland Insurance Administration approval
- University / College / Institute — may require Maryland Higher Education Commission approval if implying degree-granting authority
- Engineer / Engineering / Surveying — may require approval from Maryland Board for Professional Engineers if implying licensed engineering services
- Attorney / Lawyer / Law — may require coordination with the Maryland State Bar if implying a law firm
- Federal / National / United States / State of Maryland — prohibited unless genuine government affiliation exists
- Lottery / Lotto — restricted due to Maryland Lottery and Gaming Control Agency oversight
How to reserve an LLC name in Maryland
Maryland allows you to reserve an LLC name for 30 days by filing a Name Reservation application with SDAT. The filing fee is $25 and can be submitted online through the Business Express portal or by mail. Reservations are not renewable — once the 30-day period expires, the name returns to general availability. If you need more time, you must submit a new reservation application and pay the fee again, and there is no guarantee the name will still be available.
Tips for choosing an LLC name that passes in Maryland
- Search both the full name and individual keywords — SDAT's distinguishability test looks at the overall commercial impression of a name, not just exact character matches.
- Check the USPTO federal trademark database at www.uspto.gov/trademarks to ensure your chosen name does not infringe on a registered mark, which could expose you to legal liability even after SDAT approves the name.
- Verify domain name availability before committing to a name — a Maryland LLC approval does not secure any internet presence, and your preferred .com domain may already be taken.
- Avoid names that rely solely on geographic descriptors (e.g., 'Maryland Plumbing LLC') combined with a common service term, as these are frequently similar to existing registrations in the SDAT database.
- Search dissolved and forfeited entities as well as active ones — Maryland's distinguishability rules can apply to recently closed businesses, and SDAT reviewers have discretion in flagging those conflicts.
- Consider how your name will appear on professional licenses, contracts, and invoices — names with unusual abbreviations or punctuation can create administrative complications even if they pass SDAT review.
Maryland LLC name search: frequently asked questions
How do I perform a Maryland LLC name search?
You can search for available LLC names using the Maryland SDAT Business Express entity search tool at https://egov.maryland.gov/BusinessExpress/EntitySearch. Enter your desired name or a keyword and review all results, including similar spellings and abbreviations. The search is free and available 24/7 without creating an account. Keep in mind that a clean search result does not guarantee SDAT will approve your name, since reviewers apply a subjective distinguishability standard during the actual filing review.
How do I check LLC name availability in Maryland?
Visit the SDAT Business Express portal and use the Entity Name Search to look up your proposed LLC name. Review not just exact matches but also phonetically similar names and common abbreviations that SDAT might consider confusingly similar. You should also check for reserved names, as those are included in the database and block the use of that name for 30 days. For added certainty, you can call the SDAT Business Services Division at 410-767-1340 to ask a reviewer informally whether your name appears distinguishable.
What are Maryland's LLC naming rules?
Maryland law requires every LLC name to include 'Limited Liability Company,' 'LLC,' or 'L.L.C.' as a designator. The name must be distinguishable from all other entity names on record with SDAT, and it cannot imply government affiliation or use regulated professional terms without the appropriate agency's approval. Maryland's distinguishability test focuses on the overall commercial impression of the name, so minor differences in spelling, punctuation, or word order may not be sufficient to make two names distinct.
How do I reserve an LLC name in Maryland?
Maryland allows name reservations for 30 days by filing a Name Reservation request through the SDAT Business Express portal or by mailing a paper application to the SDAT office. The filing fee is $25, and the reservation is non-renewable — if you do not file your Articles of Organization within the 30-day window, the name becomes available again. You can submit a new reservation application after expiration, but approval is not guaranteed if another party has claimed the name in the interim.
What if my LLC name is already taken in Maryland?
If SDAT determines your chosen name is not distinguishable from an existing registration, your Articles of Organization will be rejected and you will need to refile with a different name. You can modify your proposed name by adding a distinctive word, changing the word order, or using a different abbreviation to create a clearly distinguishable identity. It is also worth checking whether the conflicting entity is still active — if it is dissolved or forfeited, you may be able to request a determination from SDAT about whether the name is available. In some cases, you can obtain written consent from the existing entity to use a similar name.
Does a Maryland LLC name need to include 'LLC'?
Yes, Maryland law under the Corporations and Associations Article § 4A-204 requires that every LLC name include the designator 'Limited Liability Company,' 'LLC,' or 'L.L.C.' — this is not optional. The designator must appear as part of the official registered name on all formation documents filed with SDAT. However, once registered, Maryland law does permit an LLC to conduct business under a trade name (also called a fictitious name or DBA) that does not include the LLC designator, provided the trade name is separately registered with the appropriate county or state office.
