Geographic Coverage and Administration
The 3543 area code serves the administrative territory of Dorkovo, which falls under the municipality of Rakitovo. This area is predominantly rural, with a population of a few thousand residents.

Dialing Formats
For callers within Bulgaria, the national trunk prefix is 0, followed by the area code and the subscriber number. The local subscriber number for Dorkovo typically consists of 6 digits, making the complete national format 0 3543 XX XX XX. For example, a local number might be 0 3543 12 34 56.
When calling from abroad, the international access code (00 or +) is used, followed by the Bulgarian country code 359, then the area code without the leading zero, and the subscriber number. Thus, the same number would be dialed as +359 3543 12 34 56.
It is important to note that when dialing locally within the same area code, callers may sometimes omit the area code, but it is always safe to include the full national number to avoid errors.
