The Latvian telephone numbering plan is a telephone number assigning system used in Latvia. All the numbers consist of 8 digits with exceptions for special services. The assigning process is controlled by the Electronic Communications Office () and regulated by the Public Utilities Commission ().
The country code for Latvia is +371. The international dialling prefix is "00". The country does not use trunk prefix. However, in 2008, the "6" was prepended to all landlines, and "2" to all mobile numbers.
During the Soviet occupation and until the transition in 1993, Latvia had the area code.
The 5-series is currently only reserved for future use. The 6-series is generally used for landlines and the 7-series is used with payphones throughout the country.
A variety of service numbers are assigned in the 1-series with lengths shorter than the standard 8 digits. Some of these services also provide 8-digit geographical numbers to be reachable from abroad.
Calls to 112 are answered on average within 6 seconds and are answered in Latvian, English and Russian. In 98% of cases, the operator can detect the location of the caller within a minute.
