# How Can I Upload a Header Document Using the Docs Manager in SMSGatewayCenter?

Uploading a header document ensures you have the necessary approvals for [SMS headers](https://www.smsgatewaycenter.com/blog/kb-cat/sender-id/), which is critical for compliance. Here’s how to do it:

- **Steps to Upload a Header Document**:
  - **Log In**: Sign in to your SMSGatewayCenter account.
  - **Navigate to Docs Manager**: Go to the *Manage Uploaded Documents* section.
  - **Access the Upload Option**: Click the *Upload* button to reveal a dropdown menu.
  - **Select Upload Header**: Choose *Upload Header* from the dropdown.
  - **Fill Out the Form**:
    - *Document Type*: Select *Header Approved by Operators* from the dropdown menu.
    - *Title*: Enter a descriptive title for the document (e.g., “Operator A Header Approval 2025”).
    - *Operator*: Choose the relevant operator from the dropdown (e.g., “Operator A”).
    - *Entity ID*: Enter the entity ID associated with the document (e.g., ENT12345).
    - *Sender Name and Header ID* (if required): Provide the sender’s name (e.g., “Sender123”) and header ID (e.g., HDR12345).
    - *Upload File*: Click *Choose File* to select the document from your device (allowed formats: PNG, JPG, PDF; maximum size: 10 MB).
  - **Save Changes**: Click *Save Changes* to upload the document to the *Header Docs* tab.
- **Best Practices**:
  - Ensure the document file is in a supported format (PNG, JPG, or PDF) and under 10 MB to avoid upload errors.
  - Use a clear, descriptive title (e.g., “Operator A Header Approval May 2025”) to make the document easy to find later.
