Yes, the Czech Republic dialing code is +420 for every Czech phone number—mobile or landline. Inside Czechia, you dial just the 9 digits; from abroad, you prepend +420 (or an exit code like 00/011 then 420). This universal format is part of the country’s closed numbering plan, which removed the old trunk “0” years ago.
Why it matters: Saving contacts with +420 prevents SMS failures when you travel and ensures transfer updates arrive reliably. Especially useful for expats and frequent senders.
Most mistakes happen when people add an extra 0, or save a local-only format (like 212…) without +420. Avoid both.
ACE tip: Ask your recipient to send you a “hi” text first; save the thread contact as +420… so OTPs and payout notifications never miss.
Czechia runs a closed plan: you always dial all 9 digits. But landlines still reveal geographic prefixes. For example, 2 for Prague and 37x for Plzeň—while mobiles typically begin with 6xx or 7xx. For planning and verifying numbers, these patterns are still handy (even with number portability on mobiles).
These are common landline patterns. Mobiles usually start 6xx/7xx. Always save as +420 XXX XXX XXX.
| City | Typical landline prefix pattern | Example saved contact (+420 …) | Note |
Prague (Praha) | 2xx | +420 212 345 678 | Capital; dense VoIP use |
Brno | 51x / 53x / 54x | +420 531 234 567 | South Moravia |
Ostrava | 55x / 59x | +420 591 234 567 | Moravian-Silesian |
Plzeň (Pilsen) | 37x | +420 371 234 567 | West Bohemia |
Liberec | 48x | +420 481 234 567 | North Bohemia |
Hradec Králové | 49x | +420 491 234 567 | Hradec Region |
Pardubice | 46x | +420 461 234 567 | Pardubice Region |
České Budějovice | 38x / 39x | +420 381 234 567 | South Bohemia |
Ústí nad Labem | 41x / 47x | +420 471 234 567 | Ústí Region |
Olomouc | 58x | +420 581 234 567 | Central Moravia |
Zlín | 57x | +420 571 234 567 | Zlín Region |
Karlovy Vary | 35x | +420 351 234 567 | Spa region |
These patterns reflect the official closed plan and long-standing regional ranges; Prague’s 2xx block and regional 3–5xx series remain the norm for geographic lines, while mobile ranges use 6xx/7xx blocks across operators.

The czech country code (+420) is the gateway for all international calls and SMS. The next digits indicate network/region: mobiles often begin with 601–608, 72x, 73x, 77x, 79x, while landlines show the 2/3/4/5 regional blocks. Because numbers are portable, a 73x mobile might now sit on another network—but your dialing format stays the same: +420 + 9 digits.
It helps. Czechia observes CET (UTC+1) and CEST (UTC+2) in summer. Quick checks of prague weather and local time can improve pickup rates—rainy weeknights often mean people are home to confirm payout details or answer verification calls.
Using +420 with the full number cuts OTP and notification failures, speeds up beneficiary checks, and keeps your transfer status updates flowing even if you travel. Small step, big peace of mind for expats and students living in Czechia.

Save 112 (EU emergency), 150 (Fire), 155 (Medical), 158 (Police), 156 (Municipal Police). These are official and free to dial; 112 supports multiple languages, which helps new arrivals. (Research: Government portals list these numbers explicitly.)
Absolutely. Open your dialer, hold 0 for the + sign, type 420, then the 9-digit Czech number (for example, 7xx xxx xxx for mobile). Save it and send a test SMS before any time-sensitive call or transfer. For US/Canada landlines, you can also dial 011 420 … which equals +420 ….
If you remember +420 + nine digits—and save every Czech phone number that way. Your calls, OTPs, and ACE alerts just work. Thesis (repeated): Always store +420 with the full number to keep communication and ACE Money Transfer updates reliable, wherever you are.
