From the United States, dial **011** to place an international call, then **420** for Czech Republic, then the area code (drop any leading 0), followed by the local number. With Telvio you dial the same format — no prefix change needed.

## Exit codes by source country

The exit code depends on where YOU are calling from. On mobile phones and VoIP apps, use + instead.

| United States / Canada | 011 | 011 420 ... |
| United Kingdom | 00 | 00 420 ... |
| Australia | 0011 | 0011 420 ... |
| Most of Europe | 00 | 00 420 ... |
| Japan | 010 | 010 420 ... |
| From a mobile / VoIP app | + | +420 ... |

## Common mistakes

- ✕ Using the wrong exit code. Each country has its own (US: 011, UK: 00). On mobile, just use +.
- ✕ Forgetting the country code +420. Without it, the call will fail or route locally.

## Country codes that get mistaken for +420

A wrong country code does not fail cleanly. It connects — to a stranger in another country — and it bills. These are the codes a caller most plausibly dials instead of +420 when calling Czech Republic.

The reliable habit is to store Czech Republic numbers with the plus sign and the full code — +420 — rather than typing them each time. A number saved in full international form dials correctly from any country you happen to be in, and removes the whole class of mistake above.

## Calling out of Czech Republic

To dial an international number from inside Czech Republic, start with the exit code 00, then the destination country code, then the number without its own trunk prefix. The exit code belongs to the country you are calling FROM, not the one you are calling.

On a mobile, press and hold the 0 key until a plus sign appears and dial the number in full international form instead. The plus tells the network to work out the exit code itself, so the same saved number dials correctly whether you are at home or abroad — no need to remember 00 at all.

## Frequently asked questions

What is the country code for Czech Republic?

The country code for Czech Republic is +420. Dial this after your exit code (or use + on a mobile) before the local number.

How do I call Czech Republic from the United States?

From a landline: dial 011 + 420 + the local number. From a mobile or a VoIP app like Telvio: dial +420 + the local number — the + works from any country without knowing its exit code.

Czech Republic does not use a trunk prefix, so you dial the local number exactly as-is after the country code.

The exit code depends on where you are calling FROM, not the destination. The US uses 011, the UK and most of Europe use 00, Australia uses 0011. On any mobile phone or VoIP app, you can use + instead.
