Telephone Poles

Probably have better luck checking with your power company. I'm pretty sure AT&T uses contractors and no one here would know who those contractors are. Might try a local ad also.

Thanks - I found a company from DTE but figured it would be worth asking other utility companies as the material is treated.

In our area, old telephone/power poles are cut down into sections when removed from property similar to cutting trees… then placed near the curb for pickup.

If looking for treated used lumber I would recommend railroad ties.

The Home Depot is one location that sells them.
