Why get a Czech Republic (+420) number

European customers are used to strict consumer standards and trust companies that give them a local number to call or text.

With a +420 number you can serve Czech customers, suppliers and partners without opening an office in Prague, and without asking anyone to pay for an international call.

Because it's a real number on the Czech Republic telephone network, it works for normal calls and text messages — including one-time passcodes and verification SMS from apps and websites.

What's included with every Czech Republic number

Unlimited inbound texts to your Czech Republic number
500 outbound SMS per month included
1,000 outbound calling minutes per month included

Works with WhatsApp, Facebook, Google, Telegram and more

Signing up to WhatsApp, Telegram or Google with a +420 number takes a minute: enter the number in the app, then read the code in your Smart Messaging dashboard as soon as it lands.

People use Czech Republic numbers to run a separate business profile, keep a personal SIM private, or appear local to Czech contacts. If any app ever refuses the number in the first 7 days, you get a free replacement — that's our 7-day replacement guarantee.

Looking for a Czech Republic virtual number?

Most people searching for a Czech Republic virtual number want a +420 number they can use online, without a SIM card or a trip to the Czech Republic. Smart Messaging gives you exactly that — but on a real number from the Czech Republic numbering plan, not an app-only line or a shared list.

You use it in your dashboard, in any SIP app or forwarded to your own phone, and it receives standard SMS and voice calls — which is why WhatsApp, Telegram, Google and Facebook verification codes arrive like on any mobile line. Read more: virtual number vs real mobile number.
