Czechia · +420 A real Czechia number. Rented for one code.

Czech numbers are nine digits with no leading zero, and mobile numbers start with 6 or 7. From abroad you add +420 and nothing else changes. Czech ticketing, classifieds and email services confirm new accounts by SMS to that kind of number, and a rented one receives the code for a single sign-up.

O2, T-Mobile and Vodafone run the Czech mobile networks. Numbers from their ranges read as Czech mobile when a service looks them up, which is the check that decides whether the code goes out.

Nine digits, no trunk prefix

A Czech mobile number is written 601 234 567 or 777 123 456, with common mobile prefixes in the 60x, 70x, 72x, 73x, 77x and 79x ranges. With the country code the same number is +420 777 123 456. There is no 0 to drop.

Landlines start with 2 to 5, with 2 used for Prague. Most services will not send an SMS to those numbers, so a Czech number that starts with anything other than 6 or 7 is the likely reason a code never lands.

Tickets, classifieds and local email

Concert and sports ticket accounts are a common reason for a Czech number, including Ticketmaster, which asks for a phone number on new accounts. Classifieds such as Bazos confirm listings by SMS, and Seznam, the Czech portal behind a large share of local email accounts, can ask for a number at registration.

Ticket sellers cap how many tickets one person can buy, and they cancel orders spread across several accounts to get around the cap. A rented number is for one account kept apart from your personal number, which is what our acceptable use policy allows.

+420 or +421

Czechoslovakia used +42, and after the split the two countries took +420 and +421. Czech and Slovak numbers look alike and many services serve both, but a Czech service that checks for +420 will refuse a Slovak number. Pick the country the service is based in.

When the account is set up, add a recovery email so it does not depend on the number. If no code arrives in the window, the activation refunds automatically.
