We have a limited supply of temporary cards that can be issued ONLY to the following communities:
- International students with non-U.S. app stores and incompatible devices.
- User devices that do not meet the hardware requirements or without a built-in NFC connection.
- Other exceptions are on a case-by-case basis.
Please contact the Mason Card Office at the Fairfax Campus if you encounter issues activating your Mason Mobile ID.
About The Mason ID
The Mason ID is for members of the university currently studying or working at Mason. The first Mason ID is free. A card replacement for a lost, damaged, or stolen card is $25 each. To obtain your first Mason ID, follow the instructions below to complete the steps.
Note: Printing physical Mason IDs is currently unavailable. We encourage everyone to activate the Mason Mobile ID. New Mason ID users who have activated their Mason Mobile ID on and after January 6, 2025, will not be charged the $25 replacement fee if they choose to change to the physical Mason ID once available.
Students must be registered for the current semester.
Faculty/Staff, contract employees, and affiliates must complete the electronic approval hiring process.
- A valid passport;
- Driver’s license, state-issued photo ID card, U.S. military ID, or permanent resident card;
- Other valid photo ID issued by a U.S. state, territory, or the U.S. Federal Government.
The Mason ID will display your legal name. The Mason ID is for campus use and is intended to be used by the individual whose name and photo appear on the front of the card. Misuse is subject to judicial proceedings.
Your account and personal information will be kept strictly confidential as per the Family Educational Rights and Privacy Act. Outside parties will not be privileged to information about you, your account, or the purchases you make without your express consent unless such disclosure is in compliance with a court order or government legislation.
Store your Mason ID in your wallet or other secured places to avoid physical damage to the card. If treated properly, the card will last your entire stay at Mason. Do not puncture, laminate, or fold the Mason ID.
If your card is lost or stolen, deactivate your Mason ID to prevent any unauthorized usage of Mason Money and meal plans:
- Log into the Online Mason Card Office and select “Lost/Stolen Card.”
- Or contact the Mason Card Office at (703) 993-1004. If after business hours, leave a voice mail requesting that your Mason ID be deactivated, clearly stating your name, G Number, and contact information.
For a replacement Mason ID, visit the Mason Card Office on the Fairfax Campus, SciTech Campus, or Mason Square during business hours. There is a $25 fee for a card replacement.
If your newly issued Mason ID does not grant you access to buildings or spaces, contact your office or building manager for access management.
Photo Guidelines
Any special requests for exceptions must be submitted to Mason Card Office in writing, including name, G Number, and mailing address. Requestors will be notified by mail of the University’s decision. Retakes at an individual’s request will be subject to the $25 replacement fee.

Sunglasses or other articles which obscure the face are not acceptable unless required for medical reasons (an eye patch, for example). In cases of medical necessity, a note from a healthcare provider must be presented before the picture can be taken. A replacement ID should be created as soon as the item is no longer required.
Hats or other head coverings are acceptable only when required by religious beliefs, tenets, traditions or customs, and may not cover any portion of the applicant’s face.

For current physical Mason ID users, the physical Mason ID is working properly. If you opt for the Mason Mobile ID, there is no cost for switching from a physical Mason ID card to the Mason Mobile ID. However, once your Mason Mobile ID is activated, the physical card will stop functioning immediately.
Is there a cost to get a Mason Mobile ID?
There is no cost to use your Mason ID on mobile devices.
How many devices can I add?
- Apple: up to two devices (one iPhone and one Apple Watch) that are signed into iCloud with the same Apple Account
