What are the limits and requirements for file attachments when uploading to Colorado 811?

Colorado 811 allows users to upload all common file types, such as images and videos, with a generous file size limit of 5 GB per attachment. Up to 12,000 files can be uploaded per Service Area/Utility Type combination per ticket. Extremely large volumes or oversized files will be flagged by the system to prevent errors or potential abuse.

Only the following File Extensions are accepted: cad, dbf, heic, jpeg, jpg, kmz, mov, mp4, pdf, png, prj, shp, shx. We block the upload of attachments that are considered executable based on their file extensions, such as .exe, .bat, and various script files. A full list of restricted extensions is available upon request from Irth. This list is based on the file types that Amazon prohibits in email. All other file types, including videos, are allowed. 

All attachments undergo antivirus scanning and will be rejected if any virus is detected. 

If you encounter any issues or system alerts during upload, contact Colorado 811 for support.
