To find a company's Tax Number in the UK (often referred to as the Corporation Tax Unique Taxpayer Reference), you should check any corporation tax notices or official correspondence from HM Revenue & Customs (HMRC) that the company has received. If you're authorized, you can also find this number by logging into the company’s HMRC online account. If you are outside the company and need its tax number, due to GDPR and privacy laws, companies might not share this information readily. However, basic company information can be accessed through the Companies House website, though this does not include tax numbers.
