# Allocated filter altitudes

This page lists filter altitude allocations by load order group. It's updated 1-2 times per year, so might not include any recently assigned allocations.

* If you already have a Microsoft-assigned "integer" altitude, you can use it to [create your own "fractional" altitude to place a new filter in the same load order group](load-order-groups-and-altitudes-for-minifilter-drivers.md#create-an-altitude).
* If you don't have a Microsoft-assigned altitude in the appropriate load order group, [you need to request one](minifilter-altitude-request.md).

To learn more about load order groups and altitudes, see [Load order groups and altitudes for minifilter drivers](load-order-groups-and-altitudes-for-minifilter-drivers.md).

To see how a driver uses its altitude number in its INF file, see [Creating an INF file for a filter driver](creating-an-inf-file-for-a-minifilter-driver.md).
