Health System Vendor Credentialing Guide
Mayo Clinic uses Green Security for vendor credentialing. This guide covers registration, required documents, and how to get approved to work in Mayo Clinic facilities.
Log In to Green Security → Green Security Full GuideFollow these steps to register through Green Security and gain access to Mayo Clinic facilities.
Go to greensecurityllc.com/register and register as a new vendor representative. Use your company email address.
Once logged in, search for "Mayo Clinic" and select the specific facility or campus you need access to. Each location may have separate requirements.
Upload all required documentation (see checklist below). Documents must be current and match your profile information exactly.
Complete the annual Green Security credentialing fee payment ($125 a year for Level 2A non-clinical access, $275 for Level 2B or Level 3 — Green Security's published prices). This fee is separate from any Mayo Clinic charges.
Mayo Clinic will review your submission. You’ll receive an email from Green Security once approved.
Once credentialed, use the Green Security mobile app or kiosk to check in and out each time you visit a Mayo Clinic facility. Badge required on-site.
Partner offer
Need a drug screen for credentialing? The test usually is not specific to any one platform or hospital — one comprehensive panel can satisfy the requirement at nearly every facility. Our partner Accesa Labs offers a single chain-of-custody urine test that screens for 19 drugs, including fentanyl and other synthetic opioids, so one order covers you in almost every situation instead of a separate test per credentialing company.
