Czechia scrapped its trunk zero in 2002 when it adopted a closed nine-digit plan, so the number written on a Prague shopfront is exactly what follows +420. Mobiles are the 6xx and 7xx triplet ranges. Dial 00 to call out. Slovakia's numbers look similar but live under their own +421, a relic of the 1993 split.

Nine digits in three triplets; mobiles start with 6 or 7, Prague landlines with 2, other regions 3 to 5.
