What is the Difference Between Appendix and Attachment?

The difference between an appendix and an attachment lies in their purpose and how they are used in a document:

• Appendix: An appendix is a section at the end of a document, such as a book or a report, that provides additional details or examples related to the main content. It is typically used to supplement the main work and usually contains information that is not essential to understanding the main content but can be helpful for further reference. For example, an appendix in a resume might include a list of publications, awards, certifications, projects, or references relevant to the job.
• Attachment: An attachment is a separate document that is sent along with the main document, such as a cover letter, a portfolio, a writing sample, or a transcript. Unlike an appendix, which is part of the original document, an attachment is distinct and may not be directly related to the main document. Attachments are often more extensive and specific than appendices and can provide greater context for the reader, such as a hiring manager reviewing a resume.

In summary:

• An appendix is a section within a document that provides additional details or examples.
• An attachment is a separate document sent along with the main document.

When formatting and labeling your appendices and attachments, it is essential to follow the style guide or requirements of your project, institution, or client. However, some general guidelines include using a consistent numbering or lettering system, such as Appendix A, Appendix B, Appendix C, or Attachment 1, Attachment 2, Attachment 3. Using these terms correctly can avoid confusion and miscommunication.
