LLC legal name problems

[Ronald Markus]

I have a situation and I am hoping someone might have some advice or provide some general knowledge on the subject. I formed an LLC with a business name that is unique and the preparer inexplicably failed to include a comma after the legal name, I was astounded to discover this one day because I have always included the comma in my business name as a basic form of punctuation and by far and away the format in which most corporations and LLC's represent the legal name of their business. I can obviously change the business name in the state where they formed my LLC, however how legally valid are any of the registrations, agreements, payments, documents, accounts etc. including anything that has my incorrect business name? Thanks in advance for any insights or suggestions.

The IRS / state agencies don't care about existence or absence of a comma.  EIN is important.
