Nope.

Pilots are required to use oxygen IF they are above 12,500 ft for more than 30 mins, or they are above 14,000.
We're required to provide passengers with oxygen above 15,000.
These are all cabin pressure altitudes.

I think the FAA recommends using oxygen at 10,000 during the day and 5,000 at night, but I don't know anyone who follows that.
