You'll be able to provide us with your address and VAT number when signing up for a Pro subscription to AnswerThePublic.
If you didn't add any details at the time, or would like to change them, login and to go the My Account menu - change billing details, and add in your address and tax ID number.
Please note your tax Id number must have your country prefix letters (if applicable), followed by numbers with no spaces. For example, GB000000000.
Any changes will take effect from the next monthly invoice. Unfortunately we are unable to make changes to previous invoices that have already been created.
