Hi CMBaertz. QuickBooks Online prohibits PO Box addresses when registering for online payment systems due to compliance regulations. If possible, use a physical street address associated with your business instead of the PO Box.

If you don’t have a physical business address, you can use the registered business address filed with the government or tax authorities, or the location where your business operates, such as an office, warehouse, or storefront.

For rural addresses that aren’t accepted, consider temporarily using another valid physical address, like a family member’s or associate’s business address, to complete registration.

For more tips on updating your company information, check out this helpful article: Change your company name, contact info, or Business Number (BN) in QuickBooks Online.

This should help you resolve the issue and get your payment system running smoothly. If you have any further questions or additional assistance, feel free to reach out to us anytime.
