Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest counts are the ones the agency reported to the FBI, through 2025.

Blaine, Washington, in Whatcom County, has about 6,400 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the Prosecuting Attorney files charges, a case in the Whatcom County Superior Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Blaine
The FBI lists Blaine with an arrest reporting agency of its own, filed as Blaine Police Department. It reported 157 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Whatcom County Sheriff's Office is the county agency. It reported 714 arrests for 2025.
The FBI's agency list also places one more agency in Whatcom County: Western Washington University (campus police).
How Many Arrests Blaine Reports
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Blaine: 157 for 2025, 187 for 2024, 160 for 2023, 167 for 2022, 81 for 2021 and 151 for 2020.
Blaine's 157 arrests in 2025 were down 16 percent from 187 in 2024.
Through July 2026, Blaine reported 90 arrests, against 87 in the same months of 2025.
Across Whatcom County, the six agencies with all twelve months of 2025 on file reported 4,498 arrests between them.
Booking: Where People Arrested in Blaine Are Held
The county jail is where a person arrested in Blaine and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2023 the jail held about 340 people, up from about 300 in 2019. Its rated capacity in 2023 was 267 beds, and it ran at 125 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Whatcom County Sheriff's Office at apps1.whatcomcounty.us/jaildata/roster.html (page title: Whatcom County Sheriff's Office | Jail Roster), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A person sentenced to prison serves the sentence in a facility of the Washington State Department of Corrections, whose inmate locator is at doc.wa.gov/records/incarcerated-data-search/incarcerated-search.
How to Find Out About an Arrest in Blaine
Whether someone was arrested in Blaine, and what came of it, shows up in three places: the custody page of the Whatcom County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Whatcom County Superior Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at dw.courts.wa.gov); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at whatcomcounty.us/304/Prosecuting-Attorney, phone 360-410-6365).

Washington is one of the states that lets anyone look up another person's statewide criminal history: WATCH lets anyone search conviction records by name online, for $12 a search, through the Washington State Patrol. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Blaine
