A QSL card is a written confirmation that a contact (QSO) took place between two amateur radio stations. The term comes from the Q-code "QSL," meaning "I confirm receipt." Exchanging QSL cards has been a tradition in amateur radio since the early days of the hobby, and while the methods have evolved from paper cards to electronic confirmations, the purpose remains the same — to confirm and celebrate contacts.
Awards — Most amateur radio awards require confirmed contacts. You need QSL confirmations to claim awards like DXCC, WAS, WAZ, and many others. The method of confirmation (paper card, LoTW, eQSL) accepted varies by award.
Collecting — Many operators enjoy collecting QSL cards as souvenirs of their contacts. Cards often feature photographs, artwork, maps, or information about the operator's station and location. A collection of QSL cards is a tangible record of a radio career.
Courtesy — In the amateur tradition, replying to a QSL card is considered good practice. If someone sends you a card, the expectation is that you will send one back.
The traditional QSL card is a printed postcard (typically 14 × 9 cm / 5.5 × 3.5 inches) containing:
There are several ways to exchange paper QSL cards:
Direct mail — Send the card in an envelope directly to the other station's mailing address. This is the fastest method but also the most expensive, especially for international mail. For international QSLs, it is customary to include a SASE (self-addressed stamped envelope) or SAE with IRCs (International Reply Coupons) or US dollar bills (often called "green stamps") to cover return postage.
QSL bureau — Most national amateur radio societies operate a QSL bureau system. Outgoing cards are sorted by destination country and sent in bulk to the corresponding bureau abroad, which then distributes cards to individual operators. The bureau system is much cheaper than direct mail (often just a few cents per card) but slower — delivery can take several months to over a year.
To receive cards through the bureau, you typically need to be a member of your national society and maintain an "envelope" (a self-addressed, stamped envelope on file) with your incoming bureau.
QSL managers — Some operators, particularly DX stations and DXpeditions, use a QSL manager — another amateur who handles their QSL card requests and replies. The manager's callsign is published on QRZ.com and in DX bulletins. Send your card (and any return postage) to the manager rather than to the operator directly.
QSL cards can be printed through several specialist printers that serve the amateur radio community, or you can design and print your own. Many operators design their cards using graphic design software and have them commercially printed in batches.
Electronic confirmation systems have become the primary way most operators confirm contacts, especially for award purposes. They are faster, cheaper, and often more convenient than paper cards.
LoTW is operated by the ARRL (American Radio Relay League) and is the most widely accepted electronic QSL system for major awards, including DXCC. It works by having both stations upload their log data, which is then matched by the system. When both stations have uploaded a matching contact, the QSO is confirmed.
Key points about LoTW:
eQSL (eqsl.cc) is an electronic QSL exchange system that also allows operators to design and exchange virtual QSL card images. It is popular and easy to use, though not all award programs accept eQSL confirmations.
QRZ.com offers an online logbook and QSL confirmation system. Operators can upload logs, and when both stations log the same QSO, it is confirmed. QRZ's system is integrated with the popular QRZ.com callsign lookup database.
Club Log is a free online logging service particularly popular among DXers. It includes a matching system and is widely used for IOTA and DXpedition QSL confirmations. Many DXpeditions upload their logs to Club Log, allowing operators to check whether their contact has been logged before requesting a QSL card.
| Method | Speed | Cost | Award acceptance |
|---|---|---|---|
| LoTW | Fast (days to weeks) | Free (upload); fees for award applications | Widely accepted for major awards (DXCC, WAS, etc.) |
| eQSL | Fast | Free | Accepted by some programs; "AG" status required for others |
| QRZ Logbook | Fast | Free (basic) | Limited award acceptance |
| Paper via bureau | Slow (months) | Low (pennies per card) | Accepted for most awards |
| Paper direct | Moderate (weeks) | High (postage + SASE) | Accepted for most awards |
Many active operators use multiple systems simultaneously — uploading to LoTW for award credit, sending paper cards for the collecting tradition, and using eQSL or Club Log for additional confirmation paths.
