The Office stores a single contact per account. It is your responsibility to keep this information current.

- Correct a Trade Name/DBA typographical or spelling error.
- Change a Trade Name/DBA by closing the location with the existing Trade Name and opening a new location with the new Trade Name.

- Close a location if the business location is no longer operating under the reported Trade Name/DBA or address. Note: if you are closing your entire business, use the Business Closure function.
Business Closure
Operations will no longer be allowed once the business is closed. Ceasing operations will stop all mail and inactivate the business including all associated licenses.

If you have sold your business, or are closing your business account because the organization structure has changed, you can enter the new Business Account Number (BAN) when you submit your closure. If your existing business has regulatory agency licenses, our office will forward this information to the regulatory agencies to review whether licenses can be transferred to the new business.
