Performing a Texas LLC lookup is crucial when forming a Texas LLC for your business. This step is especially important to complete before you begin to use your business name in your marketing, including on business cards, posters, or online.

Here are some tips for conducting a name availability search:

  • Follow the guidelines to choose an appropriate name for your LLC.
  • Use the name availability tool to see if the business name you want is available for use in Texas.
  • Check the availability of the URL. You may want to buy it to keep others from getting it.

You can call the State Business Information Line at 512-463-5555 and tell them you're forming an LLC and you want to see if the name is available. You should have a few alternate names ready, just in case your desired name is not available. Additionally, it's best to call between 8 a.m. and 8:45 a.m. or between 4:30 p.m. and 5 p.m. CST to avoid a long wait.

You can also send an email to [email protected]. Use the subject line “LLC Name Lookup Request.” 

Example Email Format

If you are unsure as to what to write for your inquiry, follow the example email template below:

Tips for Searching Names

When performing your name search, take into account the following information:

  • Don't include the designation suffix, such as LLC.
  • Search all forms and variations of the words, such as singular and plural. This ensures the name is truly unique and there aren't any similar names.
