Class A corresponds to the CEPT licence. In countries that have implemented Recommendation T/R 61-01 you may transmit during a temporary stay without any further permit. You carry your licence document with you and put the prefix of the country you are visiting in front of your callsign, for example I/DL1XXX in Italy.
Class E corresponds to the CEPT Novice licence under ECC/REC/(05)06. It is valid in far fewer countries, and in some of them only with a guest licence.
Class N is not covered by either recommendation. Without a national guest licence it is only valid in Germany. Some countries do grant such a permit on application, Spain is the known case at the moment.
Guest licence means: operating is possible, but only with a permit you have to apply for in advance. That takes time, in Spain around four weeks for example. Spain brought this temporary guest licence for non-resident foreigners back in 2026; it is valid for three months and so also covers classes E and N. You apply through the Spanish society Fedi-EA.
Planned means: the country has told the CEPT that it intends to implement the recommendation, but has not done so yet. So you may not transmit there with this class yet. Before you travel it is worth checking the linked database, the status may have changed.
No entry means: the country has neither adopted the CEPT recommendation nor an agreement with the CEPT. Operating there is only possible with a separate permit from the local administration. Some countries make no provision for amateur radio by visitors at all.
Filtering happens in the table header, each field under its column. Each of the three text fields takes what is in its column: a country name or code, a prefix, or a word from the notes. “Guest licence” in the notes field finds the countries where that is mentioned, “Morse” the three that still want proof for HF. All fields apply together. The drop-downs filter by the value of the class column itself. They sit in the table header, each under its column, and each only lists the values that actually occur there: class N has no “planned”, so it is not offered there either. “No information” no longer appears for any class: where even the full licence is not valid, the restricted one certainly is not, so two countries with a gap in the Novice list count as a no rather than a question mark. On top of that there is “Operation possible” when more than one value qualifies. Several fields set at once apply together, so region 3 and “Class A: guest licence” shows Japan and Thailand. You sort with the column headers, a second click reverses the order.
Besides a prefix, the prefix field also takes a whole callsign you have heard. The page matches it to the country via the ITU callsign series and shows above the table which series that was. So HB9 leads to Switzerland, 4L to Georgia, K3 to the United States. That answers which country, not which station: who exactly is behind a German callsign is in the callsign lookup.
Under the country name there is a line with three details. The ITU region decides the band edges: in region 2 the 40 m band goes up to 7300 kHz, in region 1 only to 7200 kHz. If you transmit on holiday following the German band plan, you can easily be off in regions 2 and 3. Next to it is the callsign series the ITU has allocated to the country, handy for placing a station you have heard. It is allocated to the administration, not the territory, which is why overseas territories have none of their own. Last comes the time offset from UTC, worked out for right now, because the logbook uses UTC. If a country has several time zones, the range is shown.
If you enter your location above, a column with distance and bearing appears and you can sort by it. It is worked out from your location to the centre of the country, along the great circle. That is a good guide for the antenna heading, but only a rough one for large countries like Russia or the USA: their centre is thousands of kilometres from the borders.
Outside the CEPT, no entry does not automatically mean nothing is possible. Many of these countries do grant visitors a permit, it just is not in any European list. Where we could read up on the procedure at the responsible authority, it is given with the country, with the source next to it. This collection is only just starting and is far from covering every destination. Where it says nothing, the national society is the right first contact.
Each country lists its national amateur radio society where there is one. For travellers that is usually the most useful contact: that is where you find band plans, repeater lists and the way to a guest licence. Where a guest licence is needed, the DARC information sheet (in German) is listed as well.
This is a compilation, not legal advice. The CEPT recommendations and the rules of the country you visit are binding. For a longer absence or residence abroad the CEPT arrangement does not apply anyway; for that there is the HAREC procedure under T/R 61-02.
