On jail paperwork, SBI stands for State Bureau of Investigation, the statewide law enforcement agency that keeps criminal history records for the state. When you see “SBI” next to a number on booking documents, that number is your SBI number: a permanent identifier the state assigned to your fingerprints and uses to track everything in your criminal record.
What Your SBI Number Actually Is
An SBI number (called a State Identification Number, or SID, in many states) is a unique tracking number assigned to a person the first time their fingerprints are submitted to the state’s criminal records repository. Once assigned, it stays with you permanently and links to every piece of criminal history information the state collects about you going forward.
Federal regulations define the kind of information filed under that number broadly: arrests, detentions, indictments, formal charges, and any resulting disposition, including sentencing, correctional supervision, and release.1GovInfo. Code of Federal Regulations Title 28 – Section 20.3 Acquittals, dismissals, pending charges, and convictions all get filed under the same number.
The terminology varies by state. New Jersey and North Carolina call it an SBI number. Oregon, Illinois, and many others call it a SID number. The FBI uses “State Identification Number (SID)” in its own documentation. The concept is identical regardless of what your state calls it: one number, one person, one criminal history file.
Why Booking Generates One
During booking, jail staff take your fingerprints and submit them to the state identification bureau. If you’ve never been arrested before in that state, the bureau creates a new record and assigns an SBI/SID number. If you have been through the system there before, the fingerprint match pulls up your existing record. This is how the jail confirms your identity and sees your full state criminal history within minutes of your arrival.
The underlying authority for this record-keeping is federal: the Attorney General is authorized to build a national system for acquiring, classifying, and exchanging criminal identification records with state and local agencies.2GovInfo. United States Code Title 28 – Section 534 Your state’s bureau is the local node in that system.
What It Controls While You’re in Custody
The record attached to your SBI number directly affects what happens next. Correctional facilities use criminal history to make classification and housing decisions, including security level and where you are housed within the facility. The Federal Bureau of Prisons, for example, calculates a Criminal History Score based on prior sentences and convictions drawn from the NCIC Interstate Identification Index, which aggregates state records.3Federal Bureau of Prisons. Inmate Security Designation and Custody Classification State and county jails follow similar logic. A person with a long history of violent offenses receives a different housing assignment than a first-time, nonviolent arrestee, and the SBI number is how the system surfaces that history instantly.
Judges and prosecutors also pull your record using the SBI number when setting bail, negotiating plea deals, and recommending sentences. A clean record versus a lengthy one can mean the difference between release on your own recognizance and a six-figure bond.
Does Your SBI Number Follow You Across State Lines?
Your SBI/SID number tracks your history within a single state. If you’ve been arrested in multiple states, each one assigns its own number independently. The FBI bridges that gap through the Interstate Identification Index, which links state records to a federal file using your fingerprints. The FBI assigns its own identifier, called a Universal Control Number (UCN), which connects your records across all participating states.4FBI. State Identification Bureau Listing
So while your SBI number itself is state-specific, your fingerprints route authorized inquiries to every state that holds data on you. The full picture is visible nationwide to agencies allowed to see it.
How to See What’s on Your Record
You have the right to see what’s filed under your SBI number, and there are two levels worth checking: state and federal.
For your state record, contact the identification bureau in the state where you were arrested. Most states offer both name-based and fingerprint-based searches. A name-based search is faster and cheaper but only returns a probable match. A fingerprint-based search provides a confirmed, complete record. Fees generally range from about $12 to $50 depending on the state and the type of search, with fingerprint-based checks costing more. Processing times vary from a few days to a couple of weeks.
For your federal record, the FBI offers an Identity History Summary Check for $18. You can submit the request electronically or by mail, but either way you need to provide a current set of fingerprints. Electronic submissions can be fingerprinted at a participating U.S. Post Office or through an FBI-approved channeler. The FBI returns a summary of every federal arrest and any state records that were reported to the national system.5FBI. Identity History Summary Checks Frequently Asked Questions
Check both. The state record may contain arrests never reported to the FBI, and the federal record may show out-of-state arrests you didn’t realize were linked to you.
Fixing Errors on Your Record
Criminal history records are not always accurate. Arrests might be listed without their final disposition, charges that were dismissed might still appear as pending, or someone else’s record might be mixed into yours. These errors can affect bail decisions, sentencing, housing classification in jail, and employment after release.
To fix errors on your state record, contact the state identification bureau directly, often through a formal challenge or dispute process. The FBI has its own process for correcting an Identity History Summary, which may require documentation showing the correct disposition of charges.5FBI. Identity History Summary Checks Frequently Asked Questions In most cases, state-level corrections must go through the state bureau first, and those corrections then flow up to the FBI’s system.
If an employer uses a background screening company and takes adverse action based on your record, the Fair Credit Reporting Act requires the employer to give you a copy of the report and a summary of your rights beforehand. You can then dispute inaccurate information with the screening company and request a corrected report be sent to the employer.6Federal Trade Commission. Employer Background Checks and Your Rights
What Expungement Does to the Number
If a court orders your record expunged or sealed, the practical effect depends on your state’s laws. In most states, expungement does not delete your SBI/SID number from existence. The number was assigned when your fingerprints entered the system and typically remains as an identifier. What changes is the information attached to it and who can see it.
Generally, after expungement, the state identification bureau must restrict or purge the entries related to the expunged charge so they no longer appear on standard background checks. Law enforcement often retains access to sealed records for investigative purposes even when the public and employers cannot see them. Specifics vary significantly by state: some require physical deletion, others only restrict access. If you’ve received an expungement order, confirm with your state’s bureau that the record has actually been updated. The process is not always automatic, and delays or errors are common.
Why the Number Still Matters After Release
Your SBI number doesn’t expire or deactivate when you leave jail. It remains the key to your state criminal history indefinitely. Employers, landlords, licensing boards, and government agencies authorized to run criminal background checks will pull records linked to it. Knowing what your record says and whether it’s accurate is one of the most practically important things you can do after an arrest, because the information tied to that number will follow you through every background check for the rest of your life.
