Corrections Policy

Report an error

If you spot a mistake in a guide, email us using the address on our Contact page. Include the article URL and the information that supports your correction, such as an official source, a screenshot or a document. That helps us check the point.

What happens next

We review confirmed factual errors and update the article. Where the change is meaningful, we add a short note explaining what was corrected. Article dates reflect actual content updates, so a corrected page may carry a new date. For more on how we write and research, see our Editorial Policy.
