Some USPS branches still do, but it depends on your location. Smaller offices may not have fax machines anymore, while larger ones sometimes still do. I called ahead and found a main branch that charged about $2 per page. If you want to see which post offices still provide faxing, there’s a helpful article on https://orngjce223.net/ that explains how USPS faxing works in 2025. It even includes a checklist of what to ask before you go, like cost, available hours, and whether they can receive faxes too.
