The phone prefixes store a lot of information about the origin of the phone number that calls you or to which you are calling, the telephone operator to which it belongs, and more. In this guide you will learn everything you should know about phone prefixes, so you can learn more about those incoming calls from numbers that you do not have saved in your phonebook, or those suspicious WhatsApp messages from unregistered phones.
international phone prefix
The international phone codes They are two-digit numbers with a + in front. Surely you have seen it on more than one occasion on WhatsApp, or other mobile apps. These prefixes must be dialed before the telephone number to achieve communication between people who are in different countries.
These output prefixes they are different in each country, and are also known as IDD (International Direct Dialing) codes or ISD (International Subscriber Dialing) codes.
here are some country exit codes:
- Spain: +34
- Sweden: +46
- Germany: +49
- Austria: +43
- Canada and the United States: +1
- Slovenia: +386
- Finland: +358
- France: +33
- Portugal: +351
- United Kingdom: +44
- Russia: +7
- Venezuela: +58
- Swiss: +41
- Complete list
So far everything seems pretty simple. The problem comes when certain international calls and other codes need to be made. These telephone codes are regulated by the International Telecommunication Union, but the way in which the prefixes and their type are distributed are the responsibility of each country. For example, there are some of fixed length in each country and that are usually from 1 to 3 figures, or of variable length that can vary from 1 to 5 depending on the area. There are also countries in which the telephone prefixes are included in the user’s number, as is the case in Spain, that is, it is a closed numbering plan, and the opposite would be an open dialing plan.
Do not confuse open or closed numbering plan with open or closed dialing plan. They are different things. The numbering plan implies whether the prefixes and numbers have a fixed length (closed) or not (open or non-standardized). While the dial plan is the way in which calls must be made according to the area. For more information see UTI.
- Open dial plans: is the one in which local and long distance calls are not made in the same way. In other words, when making a local call, it will not be necessary to dial the telephone prefix, while if they are made outside the area with the same prefix, it is. In addition, this prefix is preceded by the network access code, which is usually 0 and is omitted if the call is made outside the country. For example:
- Calling a phone number in the Netherlands, within the Amsterdam area, would simply involve dialing that phone number XXX XXXX. But if you wanted to call outside the Amsterdam area from Amsterdam, then you would have to use 020 XXX XXXX. And if you want to do it outside the Netherlands, and call Spain, you should use +34 20 XXX XXXX. Being the Xs the telephone number that is.
- In territories that follow the North American Numbering Plan (NANP), it is somewhat different. For example, suppose you are in San Francisco, California, and you want to call within that same area by dialing XXX XXXX. To call outside of that area, then you would have to use 1 415 XXX XXXX. For mobile phones within the NANP, the initial 1 is deleted, that is, 415 XXX XXXX. Whereas if you want to call any number from outside the NANP, then +1 415 XXX XXXX would be used.
- Closed dial plans: it is the one that the user number has a fixed length, and are usually common in smaller countries, where regional prefixes are not necessary. However, there are large countries that have implemented them since they allow for more user numbers without increasing the length of the numbers. For example:
- In countries like Spain, you simply have to dial the phone number with the prefix of the province and town included XXX XX XX XX, wherever it is. On the other hand, for international calls you do have to use the international code. For example, to call from Spain to Sweden you have to use +46 XXXXXXX, the same as if you add a phone from another country in apps like WhatsApp or to your contacts, which also requires the international prefix. To call from outside Spain to Spain, you had to use 07 XXXXXXXXX before 1998, now you only need +34 XXXXXXXXX to call Spain from abroad.
On some phones, especially landlines, you can’t dial the + symbol. In that case, it would be equivalent to use 0034 to +34.
Telephone prefixes according to the mobile operator
The mobile phone numbers in Spain usually start with 6, although since 2011 those that begin with 7 also began to appear. And they were of the type 6XX XX XX XX or 7XX XX XX XX. In addition to that, depending on the prefix or the first three numbers, the telephone operator could be identified. For example:
|DIGI Mobile||Prefix 641
|Or not||Prefix 601|
|Telecable Mobile||Prefix 684|
|BT Mobile||Prefix 611|
|Mobile R||Prefix 698|
Eye! Now that is no longer reliable as many use portability to switch from one operator to another and keep the same phone number. For example, a 635 from Orange could have been acquired from Simyo, or a 644 from Simyo could have been transferred to Vodafone.
Telephone prefixes in Spain
In the Spanish territory, the landline phone prefixes They change depending on the province and the municipality where they are located. These are the trunk codes or local area codes, also known as trunk codes. They can be one or two digits, plus an extension for municipal areas.
Those that start with 5 usually correspond to IP voice telephony, used as nomadic or virtual numbers, although they can not only start with that number.

Lastly, do not forget some special cases, such as certain numbers that do not fit the standards, that can be used from any country with the same function, or that involve an additional cost in the call.
There are also some special numbers that are important to know in an emergency. For example:
- 112 is a single emergency number that works in many countries.
- 091 is from the national police.
- 092 for the local police.
- 062 Civil Guard.
- 085 or 080 firefighters.
- 061 for ambulances.
- 010 or 012 for citizen attention.
- 011 traffic information.
- 118… telephone information numbers always begin with this prefix.
- 116… is the beginning of social numbers.
On the other hand, surely you have ever been called by a very strange number with many figures. These 14 or 15 digit numbers are usually those of the switchboards. They can be from a company, a health center, a hospital, etc. To know who has called you, it is better to look for the last 9 digits of the telephone number on the Internet and you will find out.
There are some numbers or prefixes that can have an additional cost, that is, they are not included in the telephone rate you have, but are charged as an extra. However, this has changed lately with some government regulations. For example, be careful with these prefixes:
- 800 and 900 they are free as long as the third number is 0. If it is different from zero you would have to pay, like 901 or 902 or 905. The higher the third number, the more it will cost you. For example, the 901 is cheaper than the 902, and the 902 is cheaper than the 905, and so on. The same goes for the 801, 802, 803, etc.
- 118 is another of the expensive numbers. Up to 15 euros can be charged for less than 5 min of call. Therefore, they should be avoided whenever possible.
