Coordination numbers
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. You can apply for a coordination number yourself via our e-service or by filling in a printed form. You also need to book an appointment for an identity check at a service centre.
When you have been assigned a coordination number, it is valid for five years. After this period you can apply for an extension. 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.
Book an appointment for an identity check at a service centre
From 3 June 2024, you need to book an appointment for an identity check at a service centre when you
- apply for a coordination number
- apply for reactivation of a coordination number
- request a change or correction of details or identity level for the coordination number.
This also applies if you have been summoned to attend a meeting in person.
If the Swedish Tax Agency receives a coordination number request, we will send you a notice about attending an identity check. In certain circumstances, an identity check can be carried out by a passport-issuing agency such as an embassy.
You can apply for a coordination number yourself
You can apply if you:
- plan to stay in Sweden for less than one year
- have a connection to Sweden and need a coordination number
If you are going to work in Sweden for less than one year, you need to register for preliminary A-tax, or to apply for special income tax for non-residents (“SINK). You employer can apply for SINK on your behalf. For people with an employer outside Sweden, there are certain exceptions to the requirement to apply for SINK. If you don’t already have a coordination number, you need to apply for one yourself.
If you are moving to Sweden and plan to live here for one year or more, you need to register your move to Sweden.

Book an appointment for an identity check at a service centre

If you apply on a printed form, you must hand it in at the service centre when you attend for an identity check.
Bring proof of identity to the service centre
When you come in for an identity check, you must hand over your identity documentation so that we can check its validity. You need to bring the following:
- your passport or national identity card – or other document showing your identity
- your residence permit card – if you have a Swedish residence permit.
The service administrator will examine your documents and check your identity. Your documents will be returned to you straight away. 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.
Change or correct details
If you change details such as your name or citizenship, you must notify us by using our e-service Samordningsnummer. You must also book an appointment for an identity check at a service centre and show documents that confirm your identity and the new 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, use our e-service Samordningsnummer, which is in Swedish.
In some cases, a coordination number can be assigned without you applying
A coordination number can be assigned on your behalf in the following circumstances:

Applying for a Swedish passport for your child
Applying for a Swedish passport for your child
As the parent or guardian of a child with Swedish citizenship, you can apply for a Swedish passport for them at a Swedish embassy or a passport-issuing police station in Sweden.
If the child is not currently registered in Sweden, or has never been (i.e., does not have a personal identity number), the passport authority may request a coordination number from the Swedish Tax Agency if needed. If the passport office determines that the child is entitled to a Swedish passport, it will request a coordination number for the child.
A coordination number can be marked as active or inactive
A coordination number that has been assigned and is in current use is referred to as an active coordination number. In certain cases, a coordination number that is not currently in use must be marked as inactive. After five years, this happens automatically.
The Swedish Tax Agency can reactivate an inactive coordination number if it is needed. You need to visit a service centre in person for an identity check.
Active and inactive coordination numbers
Active coordination numbers
An active coordination number enables access to the following details:
- name
- date of birth
- nationality
- place of birth
- contact address
- identity level associated with the coordination number
The three identity levels are as follows:
- confirmed
- probable
- uncertain
The following details are also provided:
- date of issue
- preliminary date of registration as inactive
- reactivation date
When you are assigned a coordination number, it remains active for five years. It can be reactivated after this period if you still need it.
When a person who has a coordination number dies, the Swedish Tax Agency registers the date of death.
Inactive coordination numbers
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.
Reactivating a coordination number
Applying for reactivation of a previously assigned coordination number
When you apply for reactivation of a previously assigned coordination number you must provide full details of your connection to Sweden and why you need a coordination number. Use our e-service Samordningsnummer. The e-service is available in English and Swedish.You must also book an appointment for an identity check at a service centre and provide a current contact address.
Coordination number reactivation requests made by public authorities
Coordination number reactivation requests made by public authorities
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.
Registration of coordination numbers: three identity levels
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. If you apply yourself, you must prove your identity in order to be assigned a coordination number.
Three identity levels for coordination numbers
Coordination numbers with identity level “confirmed”
In order to be assigned a coordination number with the identity level “confirmed”, you must prove your identity in a personal visit to the Swedish Tax Agency, or the official passport authority in another country, if the request comes from a public authority. When you apply for a Swedish passport, you must prove your identity when you visit a passport office.
Coordination numbers’ identity level “probable”
If you cannot prove your identity by visiting a Swedish state service centre in person and providing a valid proof of identity document, 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. Please note: this only applies if a public authority, university or college has requested a coordination number for you.
Coordination numbers with identity level “uncertain”
In exceptional cases, the Swedish Tax Agency can issue you with a coordination number even if your identity cannot be confirmed.
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.
Coordination numbers assigned before 1 September 2023 that have not been marked as inactive
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”. This depends on whether or not your identity had been proved when we issued your coordination number, or the last time we reactivated it.
Coordination numbers: 10 digits
Coordination numbers are structured in a similar way to 10-digit personal identity numbers. The third digit is an odd number for men, and an even number for women. The first six digits are your birth date: i.e. the order of the digits is birth year, month and day, with 60 added to the day on which you were born.
Example
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).
