A coordination number is a unique identifier that the Swedish Tax Agency can assign to an individual who has never been listed in the Population Register. No two coordination numbers are identical, and you keep the same coordination number for life. (The same applies to personal identity numbers.) You must visit a Swedish state service centre in person for an identity check before the Swedish Tax Agency can issue you with a coordination number.
When we have given you a coordination number, it remains active for five years. It can then be reactivated later on if you need it. If your coordination number needs to be reactivated, the Swedish Tax Agency must verify your identity once again. This means that you must visit a Swedish state service centre in person again for another identity check. In certain cases, an identity check can also be carried out at a passport-issuing authority.
If you have been issued with a coordination number and you are subsequently listed in the Swedish Population Register, your coordination number will be replaced with a personal identity number.
If you were issued with a coordination number before 1 September 2023, and it has not been marked as inactive, its identity level will automatically be marked as confirmed.
If you were issued with a coordination number at the request of a public authority, university or college before 1 September 2023, its identity level will automatically be registered as “probable” or “uncertain”. That depends on whether your identity was determined or uncertain when we issued your coordination number, or the last time we reactivated it.
You can apply for a coordination number yourself if you need one and have a connection to Sweden. This might be the case if you own a property here and need to register for refuse collection or an electricity subscription. Alternatively, you might need to open a bank account in Sweden because you are going to study here.
To apply for a coordination number, you must visit a Swedish state service centre in person and provide proof of your identity. You must also fill in form SKV 7540 “Coordination number – individual application”, which is available here on our website. You can fill in this form before you visit a Swedish state service centre, or while you are there.
It is important that you:
It is also important that you provide as much detail as possible when you fill in the application form. This will avoid the need for the Swedish Tax Agency to request further information later on. Please attach any supporting documentation that is relevant to your application.
You must visit a Swedish state service centre in person before the Swedish Tax Agency can issue you with a coordination number.
If you apply for a coordination number for yourself at a state service centre, an identity check will be carried out when you submit your application.
When we have issued you with a coordination number, it will remain active for five years. Its status will then change to inactive, unless we receive a reactivation request from you or from a public authority.
If your coordination number needs to be reactivated, the Swedish Tax Agency must once again verify your identity. This means that you must visit a state service centre in person for another identity check.
You must bring a valid proof of identity document with you, such as a passport or national identity document. If you have a Swedish residence permit, you must also show your residence permit card. If you cannot show a valid proof of identity document, you can prove your identity by providing other documentation. The Swedish Tax Agency will then assess whether this documentation confirms your identity.
An identity check involves identifying yourself and providing your proof of identity documentation so that we can check its validity. The service administrator will check your proof of identity and any other supporting documentation you have provided. They will make a copy of your documents and give the originals back to you straight away. The Swedish Tax Agency will then assess whether this documentation confirms your identity.
If the Swedish Tax Agency receives a request for a coordination number from another public authority, for example, you will need to visit a state service centre in person for an identity check. If so, we will notify you by post. We will send this notification to the contact address registered for you with the public authority requesting the coordination number. Please make sure that the public authority in question has registered an address at which you can receive post.
The child’s parents or guardians must make and sign a joint application for the coordination number. A parent or guardian who does not sign their child’s coordination number application is required to provide a written power of attorney for someone else to sign on their behalf. The power of attorney must state that the other parent or guardian has the right to represent the child when applying for a coordination number. At least one parent or guardian must take the child to a state service centre for an identity check.

To assign you a coordination number, we need a current contact address for you. A contact address is an address at which you can receive post. You must state your contact address in your application. You can provide a contact address in Sweden or another country.
You must notify the Swedish Tax Agency if your contact address changes. You can notify us by filling in form SKV 7542.
Swedish public authorities can request a coordination number for you if they need one for their own activities. The Swedish Tax Agency can also issue you with a coordination number if you are planning to work or run a business in Sweden.
If you do not have a coordination number, the Swedish Tax Agency will assign one to you when we process your application for tax registration.
In most cases, the Swedish Tax Agency will ask you to visit a state service centre in person for an identity check before issuing you with a coordination number. If so, we will notify you by post. This notification will be sent to the contact address that you or your employer provided in your application for tax registration. This must be an address at which you can receive post.
This means that you must apply for tax registration whether or not you have a coordination number. Your employer cannot apply for a coordination number for you. However, your employer can apply for special income tax for non-residents abroad (SINK) registration on your behalf. You must register for preliminary income tax (A-tax) yourself. For further details, please read the information below.
If you are not listed in the Swedish Population Register, you must submit a tax registration application for each period of work or each income year. The length of your stay in Sweden determines how you are taxed, and how you should apply for tax registration.
If you stay in Sweden for less than six months and work for the whole or part of this period, you must pay special income tax for non-residents (SINK). Either you or your employer can register you for SINK.
Applications can be made via our e-service, or by filling in form SKV 4350 for “Special income tax for non-residents”. You do not need Swedish e-identification to use the e-service. However, you must have an e-mail address, which you can use to request a temporary login code.

If you are planning to run a business in Sweden, you should apply for F-tax approval. You can apply for F-tax approval via our e-service “Registration of foreign companies in Sweden” or by filling in form SKV 4632 “Tax application for foreign entrepreneurs”.
In most cases, you will need to visit a state service centre in person for an identity check before the Swedish Tax Agency can issue you with a coordination number. If so, we will notify you by post. We will use the contact address that you provided when you applied for F-tax approval. This must be an address at which you can receive post.
If you stay here for more than six months (i.e. you have unlimited tax liability but are not listed in the Swedish Population Register) and do not have a Swedish personal identity number or coordination number, you will be assigned a coordination number when you are approved for F-tax.
If you stay here for less than six months (i.e. you have limited tax liability), you will be assigned a special registration number (a GD number) when you are approved for F-tax.

If you are going to study in Sweden and do not have a Swedish personal identity number or coordination number, a university or college with the right to award certain qualifications can request a coordination number for you.
In most cases, you will need to visit a state service centre in person for an identity check before the Swedish Tax Agency can issue you with a coordination number. If so, we will notify you by post. We will use the contact address that you provided to the university or college. This must be an address at which you can receive post.
Swedish public authorities can request a coordination number for you if they need one to address a matter concerning you. That coordination number will then be used to identify you and to facilitate the exchange of information with other authorities and organisations.
Find out more about the rules that apply when a public authority requests a coordination number for you, or makes a reactivation request on your behalf.
The Swedish Migration Agency (“Migrationsverket”) can request a coordination number for someone who has been granted a temporary residence permit in accordance with Chapter 21 of the Aliens Act (“Utlänningslag”). This applies even if the number is not needed for their activities. However, we can only issue a coordination number if we can confirm your identity.
In most cases, if a public authority requests a coordination number for you, you will need to visit a state service centre in person for an identity check before the Swedish Tax Agency can issue the number. If so, we will notify you by post. We will use the contact address that you have provided to the public authority. This must be an address at which you can receive post. Sweden’s public authorities include the Swedish Tax Agency, the Swedish Social Insurance Agency (“Försäkringskassan”), the Swedish Migration Agency (“Migrationsverket”) and the Swedish Police.
If you have a connection to Sweden and need a coordination number for matters concerning one of these organisations, you must apply for it yourself.
Swedish public authorities can request a coordination number for you if they need one for their own activities. The Swedish Tax Agency can also issue you with a coordination number if you are planning to work or run a business in Sweden.
When the Swedish Tax Agency receives a coordination number or reactivation request for you, we will notify you that you must visit a state service centre for an identity check.
Your notification will state the final date by which you must visit a state service centre. Bring your notification with you when you visit a service centre.
This could be a home country passport or national identity document. If you have a Swedish residence permit, you must also show your residence permit card.
If you cannot show a valid proof of identity document, you can prove your identity by providing other documentation. The Swedish Tax Agency will then assess whether this documentation confirms your identity.
Details of your nearest service centre are available on this website. You do not need to book your visit.
The service administrator will check your proof of identity and any other supporting documentation you have provided. They will make a copy of your documents and give the originals back to you straight away.
When the Swedish Tax Agency has reached a decision on your case, we will send a decision notification to your contact address.
The Swedish Tax Agency registers coordination numbers in the population registration database. We mark each number with one of the following three possible identity levels: confirmed, probable or uncertain. When somebody submits an individual application for a coordination number, the Swedish Tax Agency can only assign one if the person in question has provided proof of their identity.
The Swedish Tax Agency can only mark your coordination number with a “confirmed” identity level if you visit a Swedish state service centre in person and provide a valid proof of identity document. When you apply for a Swedish passport, you must visit a passport-issuing authority and prove your identity.
During your visit, you must hand your valid proof of identity document to an administrator so that they can check it. If you cannot show a valid proof of identity document, you can prove your identity by providing other valid documentation. The Swedish Tax Agency or the passport-issuing authority will then assess whether this documentation confirms your identity. When we issue you with a coordination number, we will register your contact address and personal data in the Swedish Population Register.
If a public authority, university or college has requested a coordination number for you, and you are not able to show a proof of identity document at a Swedish state service centre, the Swedish Tax Agency must assess whether your identity is probable on the basis of other documentation you have provided. This could include copies of valid identity documents, or other types of documentation. When we issue you with a coordination number, we will register your contact address and personal data in the Swedish Population Register.
In exceptional cases, the Swedish Tax Agency can issue you with a coordination number even if your identity cannot be confirmed and is therefore uncertain. In such cases, the public authority that has requested a coordination number for you must provide us with all of the personal data available. The Swedish Tax Agency will then make an assessment on the basis of the personal data provided.
If you leave Sweden and will not have any further contact with Swedish public authorities, you should notify the Swedish Tax Agency. We will then determine whether your coordination number should be marked as inactive.
A coordination number that has been assigned and is in current use is referred to as an active coordination number. An active coordination number enables access to the following details:
The three identity levels are as follows:
The following details are also provided:
When we have issued you with a coordination number, it remains active for five years. It can then be reactivated later on if you need it. When a person who has a coordination number dies, the Swedish Tax Agency registers the date of death.
In certain cases, a coordination number that is not currently in use must be marked as inactive. After five years, this happens automatically.
If you leave Sweden and will not have any further contact with Swedish public authorities, you should notify the Swedish Tax Agency. We will then determine whether your coordination number should be marked as inactive.
An inactive coordination number can be reactivated if necessary. All of the personal data associated with the coordination number is stored in the Swedish Population Register. If your coordination number needs to be reactivated, the Swedish Tax Agency must once again verify your identity. This means that you must visit a Swedish state service centre in person for another identity check.
An inactive coordination number can be reactivated if necessary. All of the personal data associated with the coordination number is stored in the Swedish Tax Agency’s population registration database. If your coordination number needs to be reactivated, the Swedish Tax Agency must once again verify your identity. This means that you must visit a Swedish state service centre in person for another identity check.
You can also request the reactivation of your coordination number yourself. To do so, please visit a Swedish state service centre. You must fill in an application form there, providing full details of your connection to Sweden and why you need a coordination number. You must also provide a current contact address and proof of your identity.
If a public authority needs a coordination number to remain active after the five-year period, it must submit a reactivation request to the Swedish Tax Agency. You will need to show that public authority your identity documents and notify them of your current contact address. In most cases, you will need to visit a state service centre in person for an identity check. If so, we will notify you by post.
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: 701063-2391 (i.e., 70 10 03 + 60).
If you have a coordination number and wish to change or correct details about you that have been registered by the Swedish Tax Agency, please notify us by filling in form SKV 7541 “Samordningsnummer – Ny uppgift” (“Coordination number – update information”). You may need to update your personal details if your name or citizenship changes, for example.
You have to prove your identity by visiting a Swedish state service centre in person and providing a valid proof of identity document which also validates your new personal details. You must also do this if you wish to request a change in the identity level of your coordination number.
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.
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.
