How to Find Suppliers in Norway

Start with the requirement, not the search box

The most common reason supplier searches go wrong is that the search starts before the need is clear. A hypothetical example: a Trondheim engineering firm needs a subcontractor for steel fabrication. "Steel" can mean a one-person workshop, a medium-sized manufacturer or an installer. All three may be the right answer, depending on what the firm actually needs.

Before you search, write down:

• What you are buying. Goods, a service, or both? A one-off delivery or a framework agreement?
• Volume and duration. A small order can go to a small firm. A multi-year contract needs a supplier that will still be there in three years.
• Location. Does the supplier need to be on site (installation, maintenance, cleaning), or can they deliver from anywhere in Norway?
• Minimum requirements. Legal form, VAT registration, insurance, sector certifications, HSE documentation, language.
• Deal-breakers. For example: no filed accounts, ongoing bankruptcy proceedings, or no employees for a labour-intensive job.

This list becomes your filter. The rest of this guide shows how to apply it using Norwegian public sources.

Step 1: Build a long list from Enhetsregisteret

Every Norwegian legal entity is registered in Enhetsregisteret, the Central Coordinating Register for Legal Entities, run by Brønnøysundregistrene. It is open data, published under the Norwegian Licence for Open Government Data (NLOD), and searchable through a public API. For supplier discovery, four fields do most of the work.

Industry code

Each entity has at least one industry code. The codes are based on the EU's NACE classification. From 1 September 2025 Enhetsregisteret moved from the SN2007 standard to SN2025. Some groups were split or moved (for example in information and communication), so a code you used in 2024 may not return the same companies today. SSB's classification database, Klass, lists the codes in both standards.

Industry codes are self-reported when a company registers. Use them to narrow the field, not as proof of what a company actually does. A company registered as a wholesaler may also install, and vice versa. Search two or three neighbouring codes rather than one.

Location

Filter by municipality or county where the supplier's business address is registered. Remember that the registered address is the office, not necessarily where the work is done. Many service companies operate across several counties from one address.

Number of employees

The register shows a number of employees for many entities. It is a useful size filter, with two caveats: the figure can lag behind reality, and an empty value does not mean zero employees. Treat a missing number as "unknown".

Legal form

A limited company (AS) has to file annual accounts and can be checked financially. A sole proprietorship (ENK) only has to file accounts above certain size limits, so for most ENKs you will see register facts but no accounts. That does not make an ENK a worse supplier, but it changes how you check it. Sole proprietorships are also often named after the owner, which makes their details personal data under GDPR.

For more on reading these fields, see our guide to Norwegian company data and how to find Norwegian companies by industry.

Step 2: Check each candidate

A long list of 50 companies quickly becomes a shortlist of 10 once you check the basics. All of the checks below can be done with free public sources.

Organisation number and identity

Every entity has a unique nine-digit organisation number. The last digit is a check digit, so a mistyped number usually fails validation. Make sure the name, organisation number and address on the supplier's website, quote and invoice match the register. A mismatch is not always fraud, but it should always be explained.

Status: bankruptcy, winding-up and deletion

Enhetsregisteret's open data has separate fields showing whether an entity is bankrupt, under winding-up (under avvikling) or under compulsory winding-up or dissolution, with dates. An entity with any of these flags should normally be dropped from a supplier shortlist. Also check the registration date: a company registered last month may be fine, but it cannot show a track record.

VAT register (Merverdiavgiftsregisteret)

The open data also shows whether an entity is registered in the VAT register (Merverdiavgiftsregisteret). A supplier that charges Norwegian VAT on its invoices should appear there. If the register says otherwise, ask why before you pay. Note that a VAT flag can remain for a while after a bankruptcy, so always read it together with the status fields above.

Roles

The register lists the roles in an entity: the general manager (daglig leder), board members, the chair, and the auditor where there is one. Roles tell you who can sign on behalf of the company and whether the same people appear in other companies. If the same person has recently held roles in several companies that went bankrupt, that is worth knowing.

Accounts

Brønnøysundregistrene's Register of Company Accounts (Regnskapsregisteret) holds the annual accounts filed by companies with a reporting obligation. The deadline for filing is 31 July for the previous year. Look at:

• Revenue and its trend. Is the supplier big enough for your order? A single order worth a large share of a supplier's annual revenue is a risk for both of you.
• Operating result and equity. Repeated losses and negative equity are warning signs, especially for long contracts.
• Whether accounts are filed at all. A limited company that has not filed accounts after the deadline may get a late filing penalty, and if it still does not file, it can eventually be referred to the district court for compulsory dissolution.

Remember that the latest accounts describe last year, not today. For a large or critical contract, ask the supplier for more recent figures or a credit report.

Step 3: Look for evidence of capability

Register data tells you a company exists and is active. It does not tell you whether it can deliver. These public signals help.

Public tenders and contract awards

Public buyers in Norway announce procurements on Doffin, the national database operated by DFØ. Contracts above the EEA thresholds are also published on TED, the EU's procurement portal. Award notices name the winning suppliers. If a supplier has recently won a contract from a municipality or state agency for similar work, it has passed a formal qualification at least once. Note that award notices are mandatory only above the EEA thresholds, and many smaller contracts are never announced. A supplier without public contracts is not necessarily inexperienced.

Sector qualification schemes

Some industries use shared supplier registers that buyers rely on for pre-qualification:

• StartBANK is the supplier register for the Norwegian building and construction sector, established by NHO and operated by Achilles. Buyers in the sector look for suppliers with a valid registration certificate.
• Magnet JQS (previously EPIM JQS) is the joint qualification system used by operators on the Norwegian continental shelf. Some operators require suppliers to be registered there before delivering goods or services.

Ask the supplier for its registration certificate and check it with the scheme's operator. Registration shows that a supplier has provided certain documentation. It is not a guarantee of quality.

Hiring and activity

Open job ads show that a company is active and growing in a particular area. NAV's arbeidsplassen.no publishes most active vacancies in Norway. A steel fabricator advertising for welders is probably busy. That can be a good sign, or a sign of limited capacity for your order.

Red flags to take seriously

• The name, organisation number or address does not match the register.
• Bankruptcy, winding-up or dissolution flags, or a recent history of them among the people in key roles.
• A limited company with no filed accounts after the deadline.
• VAT charged on the invoice without a VAT registration.
• A very new company quoting for a large, long-term contract with no explanation.
• Pressure to pay upfront to a bank account in a name other than the supplier's.
• Industry codes and website that do not match what the supplier says it does.

None of these proves wrongdoing. Each one is a reason to ask a question before you sign.

Contacting suppliers responsibly

Asking a supplier for a quote is not marketing, but the GDPR still applies when you collect and store contact details of individuals, including sole proprietors and named employees. Use the company's general contact channels where you can, store only what you need, and delete contact data for suppliers you did not choose.

How Propler helps with supplier searches

Propler is built on Norwegian public data, so it speeds up the steps above. It does not replace your judgement.

• Free company search. The company search needs no login. It filters our copy of Enhetsregisteret (about 1.18 million entities, refreshed nightly) by industry group, county, municipality, legal form, status, number of employees and registration date. Tick-boxes narrow the list to companies with open job ads, open tenders, tenders in the last year, published contact details or a website.
• Company pages. Each company page brings together register facts, roles, the latest annual accounts where Brønnøysundregistrene has them, open job ads and EU tenders from TED that the company has announced.
• AI search for "buy" needs. In AI search (login required), describe what you need in plain language, for example "a subcontractor for steel fabrication near Trondheim with at least ten employees". The AI interprets the request, searches the register, reads accounts and websites of the best matches, and explains why each one fits. Treat the ranking as decision support. You still need to run the checks in Step 2.
• Monitoring. On Pro and Business plans, monitoring notifies you when a chosen supplier's registered facts change, for example status, number of employees or the latest accounts year.
