“There is no wifi in the forest, but we promise you’ll find a better connection.”

We invite you to disconnect while you’re in Yellowstone, but for the times where you want to keep in contact with family or post on Instagram, here’s some info on communication services in the park:

Cell Service

Cellular phone service is provided in the park by AT&T and Verizon Wireless. Because of the mountainous terrain throughout the Yellowstone area, coverage varies greatly. There are cellular towers located within the park at Canyon, Mammoth, Grant, Old Faithful, and Lake. Reception varies based on your provider and the service plan you choose.

Wi-Fi access is available to employees at the majority of dorms in the park. Service is much slower than what you are used to (we like to joke that while our Firefox might not be that fast, real Yellowstone foxes are wicked fast). Bandwidth is very limited in the park due to our remoteness and current infrastructure. Streaming and downloading is discouraged and often impossible during peak usage. So while it might be a challenge to binge-watch your favorite TV show, you can binge-watch Yellowstone’s wildlife and beautiful scenery 24/7.


Each location has a local post office. Paying for your own post office box is an option (nominal fee and pick up your mail anytime) or each location will have a designated PO Box #  and mail will be circulated by the Human Resources Office (during office hours).

Following is a list of the correct mailing addresses for each location.  Anything being delivered by UPS or FedEx MUST include the correct physical address, and anything being delivered by USPS MUST include the correct PO Box (in most locations) or IT WILL BE RETURNED.  The Location Housing Office will receive the mail from these addresses and distribute out to employees.

Best practice: Use both the PO Box AND the physical address every time:
