Overview of Danish Mobile Prefix 61
The +45 61 prefix is a non-geographic mobile network code allocated within Denmark's national numbering plan, as administered by the Danish Energy Agency (Energistyrelsen) under ITU-T E.164 recommendations. Unlike geographic area codes tied to specific cities or regions, the 61 prefix is location-independent and assigned to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) providing cellular services across the entire country. This means that a number beginning with +45 61 does not indicate the caller's or callee's physical location, but rather confirms that the number belongs to a mobile subscription.
Number Structure and Dialing Format
Danish mobile numbers, including those starting with 61, consist of eight digits in total (e.g., 61 23 45 67). When dialed from abroad, the international format is +45 followed by the eight-digit subscriber number, with no trunk prefix (Denmark does not use a national trunk prefix like '0'). For example, a complete international dialing sequence would be: +45 61 23 45 67. Domestically, callers simply dial the eight-digit number directly, e.g., 61 23 45 67. It is important to note that there is no local or regional dialing variation for mobile numbers; the same format applies nationwide.
Regulatory and Porting Considerations
Denmark implemented mobile number portability (MNP) in 2001, allowing subscribers to retain their 61-prefixed numbers when switching between MNOs or MVNOs. Consequently, the prefix does not reliably indicate the current network operator, as a number originally allocated to one provider may now be serviced by another. For routing purposes, international carriers and interconnect partners query a central number portability database to determine the correct termination network. This ensures that calls and SMS messages to +45 61 numbers are delivered accurately regardless of the underlying service provider.
Services and Usage
Numbers under the 61 prefix support a full range of mobile services, including voice, SMS, MMS, and mobile data (4G/5G). They are used for both personal and business subscriptions, and may also be assigned to IoT (Internet of Things) devices or machine-to-machine (M2M) communication modules, reflecting the flexibility of Denmark's numbering plan. As with all Danish mobile numbers, premium-rate services are not typically provisioned on 61 prefixes, which are reserved for standard two-way communication services.
Caller Guidance
For callers within Denmark, dialing a 61 number is straightforward: just enter the eight-digit number. For international callers, always use the +45 country code followed by the full eight-digit number, omitting any leading zero (none exists). Ensure that your international dialing prefix (e.g., 00 from most European countries, or 011 from North America) is used before the +45. Since 61 is a mobile prefix, callers should be aware that standard mobile call charges may apply, depending on their own tariff and roaming agreements.
