It depends on the location. Not all USPS branches offer fax services anymore, but some still do, often through third-party partnerships. It’s best to call your local office before visiting. When I checked my nearby branch, they didn’t have faxing, but the staff directed me to a nearby UPS Store that did. If you’re unsure where to go, orngjce223.net has helpful articles that list which USPS offices still provide faxing and what alternatives you can use. It’s a good starting point if you’re trying to find the most convenient fax option near you.
