Originally named O'Bar, the Azle Post Office opened in 1881. The name was changed in 1883 for Dr. Azle Stewart, who gave land for the townsite. Initially the Post Office was located in a store. Postmaster Cora Lovell moved the operation to a frame building at 141 W. Main, where it remained from 1916 to 1953. The Post Office became a community gathering place. During the 38-year term of Postmaster Elsie Gipson Parker, it also housed a small public library. A larger postal facility was erected in 1970-71, after Azle attained the rank of First Class Station.
