Coordination numbers are a way of identifying individuals who need to interact with Swedish public authorities or other parts of Swedish society, but have never been listed in the Swedish Population Register. You will keep the same coordination number for life. However, if you are subsequently listed in the Swedish Population Register and receive a personal identity number, this will be linked with your coordination number. Your coordination number will remain registered as inactive and closed for the rest of your life.
The Swedish Tax Agency is the public authority that reaches decisions about coordination numbers and issues them. Coordination numbers can be requested in two ways:
If you have already received a coordination number through contact with a public authority, a company or another organisation, you must use that number. You should not request a new number.
The status of a coordination number can vary. Public authorities that use coordination numbers receive information on their status, and assess how these numbers should be checked. The status of a coordination number can be any of the following:
A coordination number that has been assigned and is in current use is referred to as an active coordination number.
A coordination number that is not currently in use can be marked as inactive. After five years, this happens automatically, and details are recorded in the Swedish Population Register. The coordination number can be reactivated later if needed.
A coordination number may become inactive and closed for various reasons. This could happen if you have since been listed in the Swedish Population Register and have been issued with a personal identity number. It could also happen if you have been issued with another coordination number previously; in this case, your first coordination number becomes inactive and closed.
A coordination number can be deregistered when a person dies. In this case, a relative or representative of the deceased person must inform the Swedish Tax Agency of the death of the individual and the date of death. These details are then registered.
If you have a coordination number and your contact address changes, you must inform the Swedish Tax Agency of your new address. To do so, please fill in form SKV 7542 Samordningsnummer – kontaktadress (“Coordination number – contact address”), which is in Swedish. You can provide a contact address in either Sweden or another country – but you must give only one address.
You also need to inform the Swedish Tax Agency if your name, citizenship or other personal data changes.
If you are a Swedish citizen and wish to change your name, you will find further information in Swedish and various forms that you can fill in on the “Names” (“Namn”) page on our website.
If you are moving to Sweden and plan to live here for one year or more, you are generally required to be listed in the Swedish Population Register.
An inactive coordination number can be reactivated if necessary. Details of your coordination number will not disappear; they will be saved. An inactive coordination number can be reactivated in two ways:
You can ask the Swedish Tax Agency to mark your coordination number as inactive if, for example, you leave Sweden and will not have any further contact with any Swedish public authorities. If you return to Sweden and need your coordination number again, you are welcome to visit a state service centre and ask for it to be reactivated. You will need to show a valid proof of identity document.
Coordination numbers are structured in a similar way to 10-digit personal identity numbers. The first six digits are your birth date (the order of the digits is birth year, month and day), with 60 added to the day on which you were born. The next three digits are your individual number, which corresponds to a “birth number” in a personal identity number. Individual numbers are randomly selected from a series (001-999) for all individuals born on the same day. Odd numbers are used for men and even numbers for women. Your control number (the last digit of your coordination number) is calculated automatically in the same way as for personal identity numbers: i.e., on the basis of your date of birth and birth number.
A man born on 3 October 1970 whose individual number is 239 has the following coordination number:
70 10 03
No two coordination numbers are identical. If someone who has been issued with a coordination number is subsequently listed in the Swedish Population Register, their coordination number is replaced with a personal identity number. You can request an extract from the Population Register showing your coordination number.
The Swedish Tax Agency registers contact addresses for people who have coordination numbers. If the identity of an individual with a coordination number has been established, the Swedish Tax Agency will also update their address in the Swedish state personal address register (SPAR).
Your coordination number is still traceable, which means that all data related to it will continue to be saved. If you need your coordination number again, it can be reactivated. A public authority can make a reactivation request for you, or you can do so yourself by visiting a service centre and identifying yourself. The requirements are outlined above.
Public authorities and other actors in society that receive information about the status of coordination numbers, must decide for themselves which validity checks are required. If someone provides a coordination number that has been marked as inactive, this signals to public authorities and other organisations that it may be necessary to check the individual’s identity and personal data.
Your passport will remain valid even if your coordination number is marked as inactive. However, the responsible authority will request the reactivation of your coordination number when it is time to issue a new passport for you.
Your passport will remain valid even if your coordination number is marked as inactive. If you no longer need your coordination number, you do not have to renew it.
If you need your coordination number again, there are two ways for it to be reactivated. Normally, another public authority will contact the Swedish Tax Agency to request reactivation on your behalf. Alternatively, you can request it yourself by visiting a Swedish state service centre. If a public authority requests reactivation on your behalf, they will need to check your identity and personal data. To request the reactivation yourself, you must visit a state service centre in person. You will need to provide the following:
Normally, a Swedish public authority will request the reactivation of a coordination number. Under Swedish law, an individual can only request the reactivation of their own coordination number by visiting a Swedish state service centre in person. This means that you cannot request the reactivation of your own coordination number while you are abroad.
In most cases, the public authority you are in contact with will take the measures it considers necessary in regard to your situation, which includes requesting the reactivation of your coordination number if required. Often, it is sufficient for a coordination number to be traceable and reactivation is not necessary.
Coordination numbers confirm the identity of people who need to interact with Swedish public authorities or other parts of Swedish society, but have never been listed in the Swedish Population Register. Marking a coordination number as inactive has no impact on citizenship.
You keep your coordination number for life. Even if it is marked as inactive, all data will continue to be stored. If you need your coordination number again, it can be reactivated and you will be able to use the same number.
You should always state your coordination number when you contact a Swedish public authority or other organisation in Sweden – even if it is marked as inactive. The public authority will then decide whether your coordination number needs to be reactivated. If so, it will normally request a copy of your passport and a contact address.
