NMLS is an online platform for licensing mortgage loan originators, lenders, and servicers, developed by the Conference of State Bank Supervisors (CSBS) and the American Association of Residential Mortgage Regulators (AARMR). The system assigns a unique NMLS ID to each registrant, promoting transparency by allowing credential and history tracking. NMLS simplifies licensing across states by centralizing data on personal and employment history, education, and disciplinary actions, thus enhancing regulatory oversight and consumer protection while streamlining the mortgage licensing process.
