Inventory Certification

Welcome to the online Communication Use Inventory Certification site. To get started you must have the BLM authorization number (aka serial number) for your communication site lease/grant.

The online communication use inventory certification site requires the use of Microsoft Internet Explorer (IE) web browser, version 8.0 or later. IE is the BLM's standard web browser.

NOTE: Users must also allow pop ups from our site.

To submit an electronic version of your communication use inventory certification form for 2019, please:

Select the Geo State from the pick list - 2 Digit State Identifier
Select the Land Office from the pick list - 1-5 Digit BLM Land Office Identifier
Enter Prefix (if applicable) - 1 Digit Land Office Indentifier of 0 (only used for grant authorizations originally issued before 1966)
Enter Serial Number - 6 Digit Unique Indentifier for each Lease/Grant (if there are less than 6 digits, the system '0' fills the spaces from the left)
Enter Suffix (if applicable) - Typically a 1-3 Digit Identifer (numeric and/or alpha) that ties a subsequent authorization to an original authorization

If you did not enter the number correctly, have a correct number or the lease/grant has expired or been relinquished, a pop-up will direct you to call the BLM Communication Use Rent Team's toll free number (877 947-3705) for assistance.

When you have entered your serial number, click Find Inventory Form. A screen will be displayed with a list of inventory certifications previously submitted for the serial number entered.
