So everyone loved Stranger Things, right? Are we agreed on that? Well, we always hurt the ones we love. So let's not pick it apart and find anachronisms for this 1983-set show.
There are a few anachronistic vehicles and vehicles designs throughout the show, such as the yellow Ford Festiva in the school parking lot that didn't come out till 1986, a more modern design for the school bus, a 1985-88 Chevy Nova and the back end of an early '90s Dodge Van. The BMX Bikes ridden are a more modern style using a 26t / 9t gear set rather than 44t / 18t.
Some music is used on the soundtrack that comes after the show, such as The Bangles, but that's soundtrack, it doesn't really count. However when Corey Hart's I Wear My Sunglasses At Night plays on the radio a year before release, that counts. At does listening to the song "Go Nowhere" by the band Reagan Youth, recorded and released in 1984. Also it was at least six months before the Smiths released their first single, that Jonathan was able to give a song on a mix tape to his little brother in America in 1982.

Will dials 911. In 1983, small towns were not yet part of this system. And when Joyce seeks to replace her telephone, the clerk attempts to charge her.
