Why am I getting error code 81901 when trying to resubscribe?

I've got some troubleshooting solutions to fix the error you've encountered when resubscribing your QuickBooks Online (QBO) account, info-menginuity-.

The error code 81901 usually appears when you're re-subscribing in the program and the system detects the address is incorrect. We can update your business information on the Account and Settings page to fix the issue. Here's how: 

1. Go to the Gear icon on the top menu. 
2. Select Account and Settings.
3. Go to the Company tab.
4. Click anywhere in the Address section.
5. Update your Company address and all the needed information.
6. Press Save, then Done.

If you're still getting the error message, we can log in to your account using an incognito browser. Private browser prevents saving cache and cookies that sometimes cause errors when running frequently visited websites. Here are the useful shortcut keys you can use to access one:

• Ctrl+ Shift + N for Google Chrome 
• Ctrl + Shift + P for Mozilla Firefox and Microsoft Edge 
• Command + Shift + N for Safari 

 Once done, you can resubscribe your account by performing the steps below:

1. Go to the Gear icon at the upper right.
2. Choose Account and Settings under Your Company.
3. Go to the Billing & Subscription tab.
4. Select Resubscribe.
5. Enter the updated billing information.
6. Press Subscribe.

For detailed steps, you can check out this article: Resubscribe to or reactivate QuickBooks Online. If it works go back to your regular browser and clear its cache. Clearing the cache or cookies is the best way to start fresh and ensure optimal performance. Otherwise, using other supported browsers can be a good alternative too.

You can easily update your credit card info, upgrade your subscription, or make other changes to your account through the Billing & Subscription tab. To learn more about it, kindly refer to this article: Update your billing and subscription information.
