Let me help you change the numbering on the chart of accounts.

Here’s how.

1. Go to the Accounting menu.
2. Select Chart of Accounts.
3. Select Batch edit in the Action column.
4. Add account numbers in the Number column.
5. Once done, select Save and Done.

If you don't plan to use an account anymore, you can make it inactive. QuickBooks hides the account from lists and menus but keeps records of past transactions on your reports. Also, this will help you organized your accounts. To know how, check out this article. Delete account on your chart of accounts in QuickBooks Online. 

Feel free to fill me in if you have any other questions. Take care.
