SeaTac Arrest Records Search
Arrest records in SeaTac are maintained by two separate law enforcement agencies: the King County Sheriff's Office, which provides general city police services, and the Port of Seattle Police, which has jurisdiction over Sea-Tac International Airport. Both are subject to RCW 42.56, and each has its own public records process.
SeaTac Overview
King County Sheriff Records for SeaTac
SeaTac contracts with the King County Sheriff's Office for city police services. KCSO deputies are the primary law enforcement presence within SeaTac city limits, which means all arrest records generated by city police activity are held by KCSO, not the City of SeaTac itself. If you need a police report or arrest record from a SeaTac incident that did not occur at the airport, your request goes to the King County Sheriff.
The KCSO Public Disclosure Unit handles records requests. Their office is at King County Courthouse, 516 3rd Avenue W-150, Seattle WA 98104. You can submit requests through the KCSO public records portal at kingcounty.gov/depts/sheriff. For non-emergency police matters in SeaTac that have not yet resulted in a report, you can also use the online reporting system through KCSO for crimes like prowls, vandalism, and traffic complaints.
For non-emergency matters, you can reach KCSO Communications 24 hours a day at 206-296-3311. The SeaTac Police Department can be reached at 206-973-4900 for police assistance specific to SeaTac. The SeaTac Police Department is located at 4800 S. 188th Street, SeaTac WA 98188. For emergencies, always call 911.
Traffic collision reports from SeaTac go through the Washington State Patrol, not KCSO. If you were in a collision in SeaTac and need the official accident report, contact WSP directly. The State Patrol maintains those reports separately from the city police records system.
Port of Seattle Police Records
Sea-Tac International Airport sits within SeaTac city limits, but the airport is operated by the Port of Seattle. The Port has its own police force, the Port of Seattle Police Department, which has separate jurisdiction at and around the airport. Arrests that occur on Port property, including inside Sea-Tac Airport terminals, parking structures, and adjacent Port land, are documented by Port Police, not KCSO.
Port Police public records are handled through a NextRequest portal system. You can also submit requests by mail to PO Box 68727, Seattle WA 98158, or by fax to 206-787-6216. The Port Police records unit can be reached by phone at 206-787-5185. For in-person submissions, the Port Police office is on the 3rd floor of the main terminal at Sea-Tac International Airport. Staff there can take your request and answer questions about what records are available.
Port Police records are separate from general Port of Seattle public records. The Port handles a wide range of public disclosure requests across multiple departments, but police records go through the Port Police specifically. If you submit a general Port records request for police data, it may be redirected to the Port Police unit, which can slow the process. Going directly to Port Police records is faster.
The Port of Seattle Public Records page explains how to submit records requests, including arrest records handled by Port Police at Sea-Tac Airport.
For airport-related arrest records, this is the correct starting point. The Port Police handle all arrests at the airport, and their records are maintained separately from KCSO records for city incidents.
Washington State Patrol and Statewide Resources
The Washington State Patrol WATCH system at watch.wsp.wa.gov provides statewide criminal history searches for $11. WATCH covers arrests and convictions from agencies across Washington, including KCSO and Port Police records. This is the most comprehensive public-facing criminal history tool available in the state.
The WATCH portal is operated by the Washington State Patrol and covers criminal history data statewide, including arrests from King County agencies that serve SeaTac.
A WATCH search pulls from the statewide criminal history repository. It is the best single source for a complete picture of Washington arrest and conviction history for a specific person.
VINELink at vinelink.com lets you check custody status for people held in King County facilities. Arrests from SeaTac typically result in booking at King County jail. VINELink shows current custody status and lets you register for alerts when a person's status changes. The service is free and does not require creating an account for basic lookups.
The Washington Courts case search at dw.courts.wa.gov covers all state courts. SeaTac arrests that led to charges in King County District Court or Superior Court will appear there. You can search by name, filter by county, and view charges, case status, and outcomes. Airport-related arrests may also lead to federal charges depending on the offense, which would appear in federal court records rather than the state system.
Reporting Crimes and Accessing Incident Reports
For non-emergency crimes in SeaTac that do not require immediate police response, KCSO offers an online reporting system. You can use this to report vandalism, vehicle prowls, and similar property crimes. After you file an online report, you will receive a case number. That case number can help you track the report and request copies later through the KCSO public records process.
SeaTac also publishes Annual Police Services Reports through the city website. These reports cover statistics on calls for service, arrest counts, crime trends, and department operations for the year. They are a good resource for understanding overall public safety patterns in the city without going through a formal records request. The reports are posted at seatacwa.gov/services/police-services.
For arrest records tied to specific incidents, formal public records requests through KCSO are the correct path. Annual reports give aggregate data but do not identify individuals. If you need a specific incident report or arrest record, submit a records request with the date, location, and any case number you have. Including as much detail as possible in the request helps KCSO locate the right records faster.
Jail records from King County facilities are subject to RCW 70.48.100, which requires basic booking information to be public. Booking records include name, booking date, charges at intake, and facility location. Contact the King County jail directly or check the county inmate search tool for current custody information. For past bookings, a formal KCSO records request is needed.
