Hi Matt
This is amazing information and I have bookmarked this page as I work a lot on these State websites. Just wanted to check are there any APIs available from where we can access this data. I am looking for direct access to States APIs and not some 3rd party providing it. It would be great if you can include that column as well.

Hello,
I frequently use your website for business searches, and I’m thankful that a website like yours exists. It appears that the link to the North Carolina business search needs to be updated.
Kind regards,

I belong to a LLC company with four other guys and one guy acts like he is the only owner and he will not let us look at any documents or records of money coming in or out. We are going on 4 months of operation and only had one short meeting. I ask every day for a meeting and yesterday he said I am fired because of my mouth asking to many questions that I don’t need to stick my nose in. I also have more complaints about him with breaking laws and I don’t know who to turn to for help. I want to save the company before he takes it down. Any referrals for me on your end?

Thanks for this resource … you saved me HEAPS of time on a research project.
Hello Matt, It looks like the New Mexico SOS recently updated their sites/system and the link for “New Mexico Business Search” on this site may need to be updated to https://enterprise.sos.nm.gov/search/business
Matt – do you have any guidance for setting up an LLC in Puerto Rico (guidance similar to many of the step-by-step guides you provide for various states)?
Hi Mark, we don’t have a Puerto Rico LLC guide at this time. It’s on our list though, so in the near future.
Hi Matt,
It looks as if the DC link should be the following:
https://corponline.dcra.dc.gov/Home.aspx/index
The one on here takes you to another site that makes you register.
Thank you!
Hi Irina, thank you for your comment and the link. The link we have in the table though for the Business Filings Search is still correct (we added a note about a login being required). The link you shared is to validate a Basic Business License (BBL). However, an entity may exist, but may have not applied for their BBL yet. The reason being is that the BBL requires either a Home Occupation Permit or a Certificate of Occupancy first. And it takes some entities a few weeks (or longer) before they get around to the BBL and its prerequisites. So the Business Filings Search link (that requires a login) is still the best link to check whether or not an entity is formed/registered in DC. Thanks!
Hi Is there any way you can do all state search in one go?
Hi Irfan, not that I know of.
Hello. my name is Thomas and I’m from Sweden. I was told in Sweden to contact “secretary of state Illinois” if I want to get information about company in the US. I am interested in company called “Global Capital Recovery LLC” 330 S Wells St – Suite 822 Chicago, IL 60606-7100. But their website doesn’t work. I tried https://www.ilsos.gov/, can you help me? Do you have their email or phone number?
Kind Regards,
Thomas
Hi Thomas, for some reason the Illinois Secretary of State blocks web traffic from most countries. Here are two phone numbers for them: 217-782-6961 and 217-782-6875. You can also use a proxy site like Hide me in order to access their website. Hope that helps.
