MLRS Overview

The Bureau of Land Management (BLM) is developing the Mineral & Land Records System (MLRS) to replace the Legacy Rehost 2000 (LR2000) case management system, Alaska Land Information System (ALIS), and land status records (e.g., Master Title Plats, Historical Indices, Tract Books).

MLRS is a customer-centric, geospatially enabled land information system that employs nationally standardized business processes, ensuring the quality and accuracy of land and mineral records and data while securely delivering land records information to relevant BLM staff, customers, and the public.

MLRS is currently available for mining claims, oil and gas, and geothermal cases. Over the next two years, additional MLRS modules will be released in support of land use authorizations and realty billing; coal and other mineral development; land and mineral title; and withdrawals, classifications, and other actions on Federal lands and mineral estate.

What can I do as a registered user in MLRS for Oil & Gas and Geothermal case types?

MLRS enables you to view your cases through the online portal. You can:

Track your case status
View and bookmark current and historic land information on the research map
Access a custom view of your leases and agreements
Create and modify your MLRS profile

Please note: to create and track lease nominations, you will continue to use the National Fluids Lease Sale System (NFLSS).

When will Oil & Gas and Geothermal cases be available in MLRS?

Oil & gas and geothermal cases are available in MLRS as of March 14, 2022.

Does the introduction of MLRS change anything for Oil & Gas and Geothermal businesses or individual lessees?

The MLRS system does not change processes but enhances how you interact with case data online. Businesses and individual lessees have transparency into tracking and viewing their leases and agreements with the MLRS system from the convenience of a computer or mobile device.

I heard the BLM's serial numbers are changing. What is the new format and what else do I need to know?

With MLRS, the BLM is transforming the standardized serial number format nationwide. The new format is: two-letter abbreviation for the geographic state, two letters for the BLM administrative state, and nine digits. For example, NMNM12345789. With MLRS, you can view and search for existing cases with the new unique MLRS-generated serial number or your current legacy serial number. New cases will not have a legacy serial number.

Will Operators need to change anything on the ground because of the new serial number?

Operators will not need to change anything on the ground. They will be able to keep the legacy serial number on all existing signage with BLM.

How does MLRS interact with NFLSS? Is NFLSS going away?

MLRS and NFLSS will share data. NFLSS will not be shut down; rather it will work with MLRS by automatically sending updated information to MLRS. All pre-leasing activities will still use NFLSS. Post-leasing actions will be handled by BLM staff in MLRS, and will be viewable by customers in MLRS too.
