All communications on ham radio have a callsign associated with them. With only a callsign, it can be difficult to know exactly who you are talking to and where to send QSL cards to and other information about the operator.

US Callsign lookups

In the United States it is the easiest to lookup as the FCC publishes the names and addresses of all licensed hams online. Most other regions of the world do not do this. Here are some methods to access this data.

ULS

FCC Universal Licensing System is the definitive source of information about licenses in the Amateur Service and several other services. New US callsigns and changes to existing licenses appear here before any of the other sources. Available queries include name, call sign, city, or zip code. The ULS is slow to respond to queries and often unavailable.

US amateur radio license map by KT1F

haminfo.tetranz.com provides a map showing all hams in a region. The map can be centered on a callsign, Maidenhead grid square, zip code, or street address. Ham locations are determined using the official address in the ULS, which is often but not always the ham's home.

WM7D

WM7D callsign database includes all US and Canadian hams, as well as some hams in other countries.

QRZ

QRZ.com also known as "Que Arr Zed" or "Que Arr Zee" is an amateur radio callsign lookup site. Besides just showing names and postal addresses for operators (primarly US operators but operators can opt in to share their info on QRZ if they are not from the US), QRZ allows for operators to put a short biography and a photo on their lookup page.

AE7Q

Amateur Extra 7 Query tools also known as AE7Q is a site most notably known for their US Vanity callsign lookup. It shows whether or not a callsign is available for assignment and once an application has been submitted to the FCC the odds of the applicant getting the callsign they applied for.

Other Countries

Germany

In Germany a list of all amateur radio callsigns is published by the Bundesnetzagentur (Federal Network Agency) at bundesnetzagenur.de. There is also a tool where you can search for specific callsigns here.
