Q1. How do I add an attachment to my online filing?
A1.  Instructions for adding an attachment.


Q2. What types of document formats may be attached to an online filing?
A2.  Attachments to online filings must be in PDF (portable document format) or TXT (text) format . If filing a trademark document, you can also use JPG. Rich Text Format (.rtf) should not be used. Our software does not currently handle documents signed using electronic signature technology.


Q3. How large can my attachment be?
A3.  Each attachment can be no larger than 4MB. To check the size of a document, right click the document name and choose Properties. Up to five attachments may be added to an online filing.

If scanning results in documents larger than 4MB, scan the document and save each page as a separate file, then add each one as a separate attachment (up to five).


Q4. How can I view my attachment while filing online?
A4.  While completing a document, once an attachment is added, the Manage Attachments page will indicate an attachment has been included with the filing. To view the attachment, click the document name link. This link will be the name of the attachment as saved on the filer’s computer. You should always check your attachment to make sure that you have added the correct one. Once the document is filed, you can only correct mistakes by filing another form.  After viewing the attachment, click your web browser’s Back button to return to the Manage Attachments page.

To remove an attachment before the filing is completed, select the check box next to the document title on the Manage Attachments page and click “Delete Attachments”. This will remove any attachments in which the text box was checked.

When you click “Continue”, you will be taken to the Review page. The Review page will provide an image of the form you completed including the document(s) you attached.  If the attachment needs to be changed, click “Return to Form” at the bottom of the screen to return to the Manage Attachments page.


Q5. How can I verify that my attachment is filed?
A5.  To view the attachment of a filed document:
  1. From the Business home, select " Search " from the left-navigation or select “Search business database”
  2. Enter the name or ID number. Click on “Search”.
    If you enter a name, a list of search results will be displayed. Select the ID Number of your record.

  4. Click on the document number to view a document.
  5. A PDF image of the document will open.  The last page(s) of the PDF image will be the attachment(s).
