I’m trying to set up my company information. I’m in the Uk. It won’t accept my postcode

Hello there, @nicolaglithero-s. Let me help you set up your company.

QuickBooks Online (QBO) uses the pre-built address data specific to the United Kingdom. To validate your address with the correct postcode, I suggest using this postcode finder: https://www.postoffice.co.uk/postcode-finder. 

Once verified, try setting up your company again. If the same thing happens, try accessing QBO on a private or incognito window. It'll help us check if this is a browser issue or not. 

You can use the keyboard shortcuts below:

• Chrome: Ctrl+Shift+N
• Firefox: Ctrl+Shift+
• Safari: Command+Shift+N

If it works, clear your browser's cache to delete all the browsing history. You can also use other supported web browsers to roll out the possibility of a browser-related issue.

Please let me know what the results are. I'm always around to assist you again. Have a good one.
