About findmycode

findmycode helps small business owners pick the right industry code: NAICS in the United States and SIC in the United Kingdom. The code you choose decides which SBA size limit applies to you, which federal contracts you can bid on, and how your company is described on the Companies House register.

The official sources are accurate but hard to search. The Census NAICS manual alone runs to hundreds of pages. We take those files as they are, keep them up to date automatically, and put the answer, the definition and the size limit on one fast page.

What we promise

• Every code, definition and size standard comes from a government source, linked on the page.
• A "data last changed" date that only moves when the official data actually changes.
• Every code in a business-type guide is checked against the official Census and ONS index before the guide is published.
• The site is free and needs no sign-up.

Who runs findmycode

findmycode is built and run by Devendra Singh Yadav, an AI engineer based in Delhi, India, with a B.Tech in engineering. He designed the pipeline that downloads the official Census, SBA, ONS and Companies House files every day and turns them into these pages, and the checks every business guide has to pass before it goes live.

If you spot a code that looks wrong, or a business type we should cover, write to [email protected]. Every correction is checked against the official source before the page is updated.

What we aren't

findmycode is independent and not affiliated with the US Census Bureau, the SBA, the Office for National Statistics or Companies House. It's information, not legal, tax or contracting advice; the agency you file with makes the final call.
