How do I dial mobiles vs landlines in Czech Republic

Czechia uses country code +420 and a closed 9-digit plan. From abroad, dial your exit code → 420 → the 9 digits (no leading 0). Inside Czechia, you also dial the same 9 digits for all calls; international calls placed from Czechia use the 00 prefix. The closed plan and removal of the trunk 0 have been in place since 22 September 2002.

Mobiles vs landlines: Geographic fixed lines start with region identifiers (e.g., 2 for Prague, 51/53/54 South Moravia). Mobile numbers don’t use area codes; they start with operator prefixes like 601–608, 72x, 73x, 77x, 79x. Because mobile number portability has been active since 2006, prefixes show the original allocation only—always dial the full number exactly as written.

Notes: Emergency numbers in Czechia: 112 (EU emergency), 155 (ambulance), 158 (police), 150 (fire), 156 (municipal police). Useful to know when calling locally.

Which mobile prefixes do mobile operators use in Czech Republic

Dialing tip: From North America, dial 011 420 + the 9-digit mobile; from most of Europe, 00 420 + number (or just +420 on mobiles). If a contact shows 0 before the prefix (e.g., 0601…), that’s legacy—drop it and use +420 601….
