Use the country explorer to check a destination’s plug types, nominal voltage, supply frequency and grounding information. Each record is a destination electrical reference, not a recommendation based on your home plug or the device you are carrying.

What the country record shows
The country database separates the electrical details that describe the destination itself. Depending on the available record, the explorer can show plug types, nominal voltage, supply frequency, grounding information, review date and source records.
- Plug types: the plug and socket standards commonly associated with the destination.
- Nominal voltage: the voltage used by the local supply system.
- Supply frequency: the mains frequency, normally stated in hertz (Hz).
- Grounding: information about whether the listed outlet system normally provides an earth or grounding connection.
- Review and sources: the date the record was reviewed and the source records available for that destination.
Plug types are country standards, not trip matches
A country can use one plug type or several. The plug-type record describes the outlets associated with the destination; it does not by itself tell a traveler whether an adapter is required. That depends on the plug being brought from the traveler’s home country.
For example, two travelers visiting the same destination can receive different adapter results if they start with different home plugs. The electrical standard stays the same, while the travel match changes.
Nominal voltage
Nominal voltage describes the destination supply. It should be compared with the input rating printed on a charger, power supply or appliance before use. A country voltage record does not mean every device from another country needs a converter.
Many modern chargers are marked Input: 100–240V and are designed for a broad voltage range. Single-voltage equipment needs a closer device-specific check. A plug adapter does not convert voltage.
Supply frequency
Supply frequency is normally shown as 50Hz or 60Hz. Many electronic chargers accept both when the label states 50/60Hz. Motors, clocks, pumps and some timing-dependent equipment can be more sensitive, so the destination frequency should be checked against the exact device label.
Grounding information
Grounding describes whether the outlet system normally provides an earth connection and how that connection is delivered through the plug standard. A grounded device should not be treated as safely grounded merely because an adapter makes the plug fit. The adapter and outlet arrangement must preserve the required connection.
Countries can use more than one plug type
Some destinations list several plug types because more than one socket standard is in use. The mix can reflect local installations, older infrastructure, imported equipment or regional practice. When several types are listed, do not assume every outlet in the country accepts every listed plug.
Country standards can include local exceptions
Hotels, older buildings, remote facilities and territories may not follow one uniform outlet pattern. Check the notes shown for the selected destination and confirm unusual or high-power equipment before travel.
Review dates and source records
The review date indicates when the destination record was last checked in the AdapterMatch country database. Available source records provide the supporting reference trail for the electrical data shown by the explorer.
Need to know which adapter your trip requires?
This page describes the destination electrical standard. To compare a home country, destination and device and determine whether a plug adapter or voltage converter may be needed, use Travel Adapter by Country.
FAQ
Where can I check plug types by country?
Select a destination in the country explorer above. The record shows the plug types associated with that destination together with the other electrical data available for it.
Does a country plug type tell me whether I need an adapter?
No. The destination plug type tells you which outlet standard is used there. Whether you need an adapter depends on whether the plug you are bringing fits that outlet.
What is nominal voltage?
Nominal voltage is the stated voltage of the destination power system. Compare it with the input voltage printed on the device or charger before connecting equipment.
Why can one country have several plug types?
More than one socket standard can be in use within the same country. Building age, local installations and regional differences can affect which outlet is actually available.
What is the difference between voltage and frequency?
Voltage is the electrical potential supplied by the power system, while frequency describes how often alternating current cycles each second. Both should be compared with the device rating when relevant.
