QRZ.com commenced in October 1993. The creator is Fred Lloyd AA7BQ.
QRZ.com was one of the first 25,000 sites on the internet.
The website houses 'almost' every callsign in the world. The website features a forums page, where amateur radio operators can add products they would like to sell, or general topics and Q&A. The website offers registered users a webpage where they can post pictures of their ham radio shack, and tell cool facts about themselves. Their page also provides their email address, and mailing address for other radio amateurs to send them QSL cards.
