What type of work should I list for my business?

[wctaxprep]

My sole-member LLC provides digital content design and development services, including graphic design, marketing, website design and development, and mobile app design and development. What IRS Business Activity code should I use? 541900 Other professional, scientific, and technical services? 

Thank you in advance for your assistance!

That would work.

It's 541990, not 541900.

Thanks, I appreciate the input.

I appreciate you clarifying that, thank you!
