Look up any company, in any state.

No, and the differences are not cosmetic. States use different identifiers, different status vocabularies, and different amounts of public detail. Some let you search by officer or Registered Agent; others only by name and number. A result in one state is not directly comparable to a result in another, which is why each state page sets out that state's own vocabulary before it explains what to do with it.

Each state writes its own. Active, In Existence and Good Standing all describe a record with nothing outstanding. Suspended, forfeited, void, dissolved and involuntarily terminated all describe a record with something wrong, and they do not describe the same thing as each other. Some are administrative and reversible by filing what was missed. Others end the entity. The state page maps every label yours uses to what has to happen next.

Sometimes. Some states publish managers, officers or members alongside the entity record and let you search by them. Others deliberately keep LLC ownership off the public register, so the search confirms the company exists, shows its Registered Agent and its standing, and tells you nothing about the people behind it. Which of those you are dealing with depends entirely on the state you are searching.

Usually the name. Registers match the legal name on file, not the name on the sign, so a company trading under one name is often registered under another. Punctuation, entity endings and abbreviations all affect the match, and searching a distinctive fragment catches most of it. If it still does not appear, the entity may be registered in a different state from the one it operates in.

Find out what the state is waiting for. Usually it is a periodic report, a Registered Agent that lapsed, or a tax filing that keeps the record current, and standing returns once the missing piece is filed. Where the entity has already been administratively closed, reinstatement is a separate filing with its own requirements. The state page sets out which route belongs to which status.

It answers a narrow question well: whether the entity exists, what the state calls its current standing, and who is on record to accept legal papers for it. It will not tell you whether the person you are dealing with can bind the company, and in states that keep ownership private it will not tell you who is behind it. Check the status close to the date you sign, not weeks before.
