- 0 555 XX XXX (where XX XXX is the local subscriber number, typically 5 digits)
For international callers, the Swedish country code +46 is used, and the leading trunk prefix is omitted. The international format is:
- +46 555 XX XXX

Geographic Coverage and Administration
The 555 area code is part of the Swedish Telecommunication Administration's numbering plan and is administered by the Swedish Post and Telecom Authority (PTS). The code is geographically allocated to the Grums exchange area, which is part of the larger Karlstad telephony region. Calls to 555 numbers are routed over the public switched telephone network (PSTN) and are subject to standard geographic call charging rates within Sweden.
Overlay and Numbering Considerations
Currently, there is no overlay code for the Grums area, meaning that 555 is the sole area code for this locality. Subscriber numbers within the 555 code are typically 5 digits long, resulting in a total national number length of 9 digits (including the leading 0). The numbering capacity is sufficient for the local population, and no changes are anticipated in the near future.
Caller Instructions
For local callers within Grums, it is necessary to dial the full national number (including the area code) even for calls within the same exchange, as Swedish numbering requires the area code for all calls outside the local network. For callers from other parts of Sweden, simply dial 0555 followed by the subscriber number. International callers should replace the leading zero with the +46 country code, ensuring that the number is correctly formatted for international dialing.
