Determining Distinguishability of Entity Names

Effective 08/12/2005; Revised 12/23/2005

Laws 2005, chapter 253, amended the naming statutes for corporations and LLCs to require that entity names only be "distinguishable" from other entity and trade names on file with the Arizona Corporation Commission and the Arizona Secretary of State. "Distinguishable" is a minimal standard. A name is "distinguishable" if it is different in any way from other entity and trade names, however, some differences do not count and are not considered in determining distinguishability. The following differences do not make a name distinguishable:

  • entity identifiers (Inc, LLC, Corporation, etc.)
  • spaces between words ("roll out now co." vs. "rollout now co.")
  • specific punctuation ("Great Expectations " vs. "Great Expectations!")
  • the case of the letters contained in the name ("TOO COOL" vs. "Too Cool")
  • the use of ampersand (&) versus "and" ("U & I Inc." vs. "U AND I Inc.")
  • the use of Arabic numerals (1,2,3,etc) and words representing these numerals ("One Stop LLC" vs. "1 Stop LLC")
  • the use of the articles "a", "an" and "the" (A Birdcage vs. The Birdcage)

The following are guidelines to be used in determining whether a name is "distinguishable."

  1. Name Length: the eCorp Database limits the number of characters for a full entity name to 120. Please note that the system will truncate (cut off) any names longer than 120 characters.
  2. Words and abbreviations that are required to identify the type of entity (called "identifiers") are disregarded when considering whether or not a name is available and do NOT qualify a name as distinguishable. This includes abbreviated forms of the identifiers as well as foreign language equivalents.
    1. IDENTIFIERS: "corporation", "corp", "company", "incorporated", "limited", "association", "co.", "Ltd.", "Inc.", "limited partnership", "limited liability company", "LLC", "L.L.C.", "limited company", "LC", "L.C.", "LLP", "L.L.P.", "limited liability limited partnership", "L.L.L.P", "LLLP","P.C.", "professional corporation", "professional service corporation", "PSC", "PLLC", "PLC", "professional association", "P.A.", "service corporation", "S.C.", "chartered", "Chtd.", "Arizona Close Corporation", and "A.C.C."
    2. EXAMPLES: "Fox Co." is NOT distinguishable from "Fox LLC"
    3. "Los Gatos S.A., Inc." is NOT distinguishable from "Los Gatos Inc."
  3. A name may NOT be comprised only of identifiers listed above.
    1. EXAMPLES: "Service Corporation, Limited" would NOT be a valid name.
    2. "Arizona Service Corporation, Limited" WOULD be a valid name.
  4. All spaces between words are eliminated and do NOT make a name distinguishable.
    1. EXAMPLE: "Right Now Co." is NOT distinguishable from "Rightnow Co."
  5. Certain symbols, punctuation marks and special characters are eliminated prior to searching for name availability, and do not qualify a name as being distinguishable. The following marks are removed prior to searching name availability:

" " (quotation marks)

. (period)

; (semicolon)

! (exclamation)

‘ (apostrophe)

\ (back slash)

| (pipe)

? (question mark)

: (colon)

` (accent)

--- (dotted line)

* (asterisk)

> < (greater than/less than)

    4. Note: If the letter "A" is intended to be used in a name as something other than an article, make sure that it is followed (without any spaces) by a period (.), dash (-) or another letter.

  3. The plural form of a word may make a name distinguishable.
    1. EXAMPLE: "Good Deed Inc." is distinguishable from "Good Deeds Inc."

    2. "Evangelical Church" is distinguishable from "Evangelico Church"
    3. "El Burrito" is distinguishable from "The Burrito" or "Burrito"

IMPORTANT: The Arizona Corporation Commission's (ACC's) role in determining whether or not an entity's name is distinguishable is ONLY ministerial. Registering or filing a name with the ACC does not grant rights or interests in that name. The ACC does not have the power to determine or settle competing claims to a name under other statutes or under common law. Even though the ACC approved a name as being distinguishable from the names of existing entities or trade names (based on the above criteria), you could still be infringing on the naming rights of other parties. In particular, if the name you select is similar to a name already protected by a federal trademark filed at the U.S. Patent and Trademark Office, you could be forced to stop using the name and possibly to disgorge profits. This can also be the case if another entity is already using a similar name in a related field, even if they do not own a federal registration. To search the database of the U.S. Patent and Trademark Office, go to: http://www.uspto.gov/main/trademarks.htm

Please also note that the Arizona Corporation Commission does not register 'Doing Business As' or d/b/a names.
