Which apps get their code on a Czech number today?

A Czech jeweller’s tray holds two stones found in Bohemia: green moldavite, from the meteorite that fell near the Vltava, and red Bohemian garnet. Here every app sold on +420 is a stone: moldavite at 50% or more, golden citrine at 20 to 49%, garnet under 20%, and rough rock where too few recent orders exist to measure. 26 of 177 apps have a measured rate.

Updated 24 Oct 2026, 01:30 UTC. Each stone opens its order page, or a country with a known rate when Czechia has none.

Is a Czech number the best route, or is a neighbour better?

What does a Czech mobile number look like?

Nine digits after +420, written in threes: +420 601 234 567. Czechoslovakia shared the code 42; after the split, Czechia took +420 on 28 February 1997 and Slovakia +421. On 22 September 2002 Czechia dropped the trunk 0, so a Czech number has nothing to drop. Mobiles start with 6 or 7.

The first three digits once named the network, such as 601 to 608 and 72x to 79x. Numbers move freely between O2, T-Mobile and Vodafone, so the prefix only tells you who issued the number first.

What can a rented Czech number not open?

Before Prague houses had numbers they had signs: a golden key, a white swan, three fiddles over the door, and that is how a letter found you. Six signs on this street, six things a one-code number cannot receive, because it goes back to the pool after 20 minutes. Turn a sign to read why.
