Definition & Explanation

A declarant submitting a transit declaration in NCTS assigns a Local Reference Number (LRN) before customs issues the system-generated MRN (Movement Reference Number). The LRN is chosen freely by the declarant but must be unique within their own operations; it ties together all electronic messages exchanged between the declarant and the customs office for that transit case. Unlike the MRN, the LRN carries no cross-authority validity and cannot be looked up by external parties. In practice, it supports internal case management and simplifies troubleshooting when messages in the electronic data exchange fail to match.
