BLM Serial Number
A unique identifier assigned by the BLM to each mining claim upon recording, used to track claims in the federal records system.
Detailed Definition
A BLM serial number is a unique identifier assigned by the Bureau of Land Management to each mining claim, mill site, or tunnel site upon recording. The serial number is used to track the claim throughout its lifecycle in the federal records system.
- NMC (Nevada Mining Claim): e.g., NMC 1234567
- AMC (Arizona Mining Claim): e.g., AMC 456789
- CMC (California Mining Claim): e.g., CMC 789012
- OMC (Oregon Mining Claim): e.g., OMC 345678
How serial numbers are assigned: - Assigned when the claim is first recorded with the BLM state office - Each claim receives a unique serial number - The number remains with the claim for its entire lifecycle - Transfers of ownership do not change the serial number
Uses of serial numbers: - Primary identifier in BLM databases (LR2000/MLRS) - Required on annual maintenance fee payments - Referenced in all BLM correspondence about the claim - Used to look up claim status, history, and documents - Essential for claim research and title examination
Research applications: Serial numbers are the key to accessing BLM records about a specific claim, including filing dates, claimant information, maintenance fee payment history, and disposition status.
