Missouri background check laws
A practitioner-grade reference to Missouri pre-employment background screening: lookback caps, ban-the-box scope, salary-history limits, cannabis testing rules, and the statutes the SafestHires compliance team applies on every order routed to MO.
The four levers at a glance
| Lookback period | 7 years (FCRA default) |
| Ban-the-Box scope | Public sector + Kansas City, Columbia, St. Louis |
| Salary history | Kansas City ordinance |
| Cannabis testing | Recreational legal (2022); off-duty protection for medical patients |
Lookback period
Missouri applies FCRA. Expunged records under RSMo §610.140 must be suppressed.
Ban-the-Box and Fair Chance rules
Governor's 2016 executive order covers state agencies; Kansas City (private 6+), Columbia, and St. Louis have local private-employer rules.
Salary history
Kansas City prohibits salary-history inquiries for private employers; no statewide rule.
Cannabis & drug testing
Amendment 3 legalized adult use and continues medical patient protections under RSMo §195.815.
