Security Information

Student Inspections

All students will be visually inspected upon entry to the line up area. Be prepared to open your gown for visual inspection. No backpacks or alcohol is allowed. We encourage you to not bring bags or purses as there is no secure location to store them and they are not allowed on the field.

Any items deemed by the University of Washington Bothell staff to be inappropriate or possibly disruptive of other guests’ enjoyment are prohibited. Violators are subject to removal from the arena and to applicable disciplinary action and/or legal action.

Guest Inspections

T-Mobile Park staff are positioned outside to provide assistance with the entry process. Guests will pass through walk through metal detectors. It is not necessary to remove cell phones, car keys or coins from pockets. If secondary screening is necessary, it will consist of a manual screen with a hand-held metal detector. Guests that are unable to undergo a metal detection searched due to medical reasons will be screened with a hand-held wand.

Any items deemed by the University of Washington Bothell staff to be inappropriate or possibly disruptive of other guests’ enjoyment are prohibited. Violators are subject to removal from the stadium and to applicable disciplinary action and/or legal action.

No. Small clutch purses no larger than 4.5″ x 6.5″, with or without a handle or strap, are permitted along with a clear bag or one-gallon plastic bag. View prohibited items

May I carry cameras, binoculars, cell phones, or tablets separately from what I put in a clear bag?

Yes. There are limitations only on the types of bags carried into these venues, not items that fans normally bring to events. Fans can continue to carry approved items in their pockets or hands such as keys, cell phones, wallets, makeup, blankets, etc., if you choose not to put them in a clear bag or clutch. In addition, you can carry a blanket over your arms, and binoculars and/or cameras around your neck or in your hands without the case and use the clear bag and clutch to carry other items. You will continue to have the flexibility to bring a wide variety of approved items into these venues.

Can I bring in food?

Outside food is permitted in single-serving sizes. Sealed, clear plastic water bottles up to 32oz, baby bottles, beverages related to medical needs, and unopened, soft-sided single serve containers like juice boxes are permitted. Soda, coffee or other beverages are not allowed. Guests may also bring in one empty plastic or reusable bottle 32 ounces or smaller.
