The code 0387 merged Langholm (formerly 0541) with Dumfries (already on 0387) into a set of new codes, all beginning 0387. Dumfries maintained the original 4-digit code with 6 digit numbers and the area merged into it added an additional digit to the code with 5 digit numbers. As part of the PhONEday changes on 16th April 1995 the codes became 01387X. The new codes for this mixed area are shown below with their locations. Unlike extended linked numbering scheme areas, calling between these areas requires the full code to be dialled before the number. Numbers within the original 4 digit 01387 code area cannot start with 3 since they would conflict with the 5 digit code area.
