did they ever show her or say her last name? Also in small southern/rural towns in the 60s like Mayberry was it really necessary to dial the operator first every time you made a phone call?

Sarah was never seen nor did she have a last name. Also, Andy & Barney never dialed Sarah, they just picked up the receiver and started talking to her.
