Overlay and Numbering Considerations
As of the latest ITU-T E.164 guidelines, no overlay codes have been introduced for the 0260 area. The numbering capacity is sufficient for the region's demand. However, with the ongoing migration from PSTN to IP-based services, some numbers may be assigned to VoIP providers, but the geographic significance remains for routing and emergency services.
When dialing from mobile phones, it is essential to include the area code even for local calls, as mobile numbers are non-geographic and require full national numbering.
