My father's company is named the following:

Xyz Trading Co. (L.L.C.)

I find the use of periods excessive, at the abbreviation of company and the last period in the parenthesis.

Is it grammatically correct?

It is grammatically correct, as L.L.C. is an acronym, and Co. is an abbreviation; but it is certainly not the only correct option. LLC is far more common than L.L.C. in company names, though Co is not as popular as Co.

I would therefore expect to see:

Xyz Trading Co. LLC

For examples, you can google "co llc" (google ignores caps and punctuation), and see what comes up.

Wikipedia has a discussion on the use of punctuation with acronyms and abbreviations; generally, either way is grammatically acceptable (with few exceptions), though periods are definitely not as popular.


Traditionally acronyms, or more properly initialisms, used a full stop / period after each letter to show that each letter stood for something. That convention has mostly died out save for a few publications such as The New Yorker and a few others. The BBC has even gone so far as to drop capitalisation of all but the first letter as soon as the initialism becomes an acronym (i.e. the letters are pronounced as a word rather than individual letters).

If you are familiar with American TV, think of M*A*S*H. Those were the good ol' days, when TV was actually written T.V.. Alas, the full stops / periods are on their way out, so feel free to write just LLC. No one will even notice.


A company can call itself anything it wants, within reasonable bounds that would exclude, for example, highly offensive phrasing. So it doesn't really make any difference whether the name is "grammatically correct".

Having said that, (L.L.C.) probably isn't "part of the name" as such anyway. The UK equivalent Plc (Public Limited Company) used to be Ltd, which I assume actually stood for Limited Liability Company as in OP's case. I think such additions are more akin to, say, educational or professional qualifications in brackets after a person's name.

Having said all that, I doubt many companies would add the periods as in OP's case. Perhaps it's quite a small outfit, and they wanted to call attention to the fact that it really is a proper "company", not just the trading name of a couple of guys in a partnership. I'm afraid it just looks a bit pretentious to me - but as I said, they can call it whatever they like.

  • I don’t think reasonable bounds or offensiveness really play that big a part—companies can name themselves anything they want, as long as they don’t infringe on copyrights, trademarks, and patents. The PLC/LLC/Ltd. bit might not be part of the name, but it might well be that it is part of the name. There are companies whose names include the company type suffix (or whatever things like PLC/LLC/Ltd. are known as) and style them in a particular way, writing “Plc” instead of “PLC” or “plc”, or writing out “Limited” as a word instead of “Ltd.” as an abbreviation.

  • @Janus: A High Court judge who declined to give a ruling in a trademark dispute over the use of the title FCUK said he found the French Connection advertising campaign "obnoxious and tasteless". On the basis of that, I think if you applied to register your business tradfing name as, say, "cunt" or "nigger", any High Court judge in the UK would quite happily support whatever government official turned down your application (or any member of the public who complained about you using it).

Having proofread a list of company sponsors for an event, many of whose names seemed to have the same structure except for the punctuation, I will confirm that they can be arbitrary and very fussy about periods and commas.

There's nothing grammatically wrong with the surfeit of periods in the OP's question, and whether any of us like it or not, I would not normalize it to what I would prefer when editing it.

I would also dispute FumbleFingers' point that (L.L.C) isn't part of the name. It is (probably) part of the company's legally registered name.

    In the UK at least, all company names have to be registered. The class of registration may be Plc, or any of several alternatives, and that itself is registered, but not normally as part of the actual name, I think. Things may be different in the US. Sep 3, 2011 at 13:23
  • @FumbleFingers I am not certain, that that is the case i.e. that the class of registration, or rather, the company type is part of the company's name in the U.S. I'm pondering "Inc." specifically. But my point here is to mention that enclosing LLC in parentheses just looks wrong. It is confusing, possibly pretentious and will cause potential customers to be puzzled. Grammatical correctness was the question, for which I have no answer, so am leaving this as a comment. Sep 3, 2011 at 15:41

When formally noting your company via RSVP, Return Address, Business Cards or Legal Documents and Proposals either L.L.C. or "L.L.C." will show appropriate form. But, as within the paragraphs of proposals, certain printed material and or guides and contractual evidence, simple space from business name and small llc can fit I.D.
