This article details the dialling protocol for reaching Hungarian telephone numbers from within Hungary. The standard landline number consists of 6 numerals except those in Budapest which have 7 numerals, as do mobile numbers. Before keying the subscriber number required, a caller may need to enter a domestic code (06) and an area code.

In Hungary the standard lengths for area codes is two, except for Budapest (the capital), which has the area code 1. Landline numbers are six digits in general; numbers in Budapest and mobile numbers are seven digits.

Calls within local areas can be made by dialling the number without the area code, such as 123 4567 in Budapest or 123 456 in other areas. However, this is not permitted in mobile phone networks.

Domestic calls to all other area codes must be preceded with 06 + area code. For example, a call from Budapest to Monor (area code 29) would be made as 06 29 123 456 and a call from Monor to Budapest (area code 1) would be made as 06 1 234 5678. When using mobile phones, the international format can be used instead: +36 1 234 5678.

Calls to international destinations are in the format 00 + country code + number. On mobile phones, + can be used instead of 00.

Calls to local areas from abroad can be made using the international prefix + country code + area code. The national trunk code 06 used inside Hungary shall not be dialed from abroad. For example, a call to Monor (area code 29) would be made as +36 29 123 456 or (if calling from a country where the international prefix is 00) 00 36 29 123 456, where the +36 or the 0036 prefixes represent the country code of Hungary.

Certain services can be called with a short number, ignoring the above scheme.
