Telephone numbers in Belarus Telephone numbers in Belarus Belarus began using its own country code +375 in 1995. Prior to that it was part of the +7 international country code. The local numbering plan was inherited from USSR and remains with little changes. Geographic area codes were designed based on previous 3-digit USSR area codes by removing the lead "0". Calling across areas still requires dialing trunk prefix 8 and waiting for dialtone after that. This pause was initially required by the analog trunk switches to identify the caller from PSTN for billing purposes. When calling within Belarus add 0 to the trunk prefix.
