Company registration by VAT ID

B2B registration process

Registration by VAT ID fetches company details from the Polish REGON register, checks VAT status and usually holds the account for approval.

What is Company registration by VAT ID?

Company registration by VAT ID is a B2B store sign-up process in which the buyer enters their tax number (NIP in Poland), and the system fetches the company's details from the REGON register via the GUS API and checks its VAT status. Polish businesses are checked against the VAT taxpayer register kept by the National Revenue Administration, known as the white list, while EU VAT numbers of companies from other member states are validated in VIES. The account then usually waits for approval, when an account manager assigns a price group and trading terms.

How we use it at Koda Plus

Company registration and verification by VAT ID is a standard part of the B2B wholesale stores we build: address details fill in automatically, the buyer's status is checked in the VAT register, and in VIES for EU companies, and the new account goes to moderation. Until an account manager approves the company and assigns a price group, the customer cannot see wholesale prices. We attach multiple users with different permissions to a single company account, such as the person placing orders, the approver and accounts. You can try registration by VAT ID in our wholesale demo at demo.koda.plus.

When it makes sense

  • Only verified businesses should see wholesale prices
  • You sell to companies in other EU countries and zero-rate intra-EU supplies
  • Every new customer is assigned a price group and credit limit
  • A long sign-up form puts buyers off

Frequently asked questions
Company registration by VAT ID

  • How can a store fetch company details from a Polish NIP number?

    Statistics Poland (GUS) provides an API to the REGON register (BIR) that returns the company name, address, REGON number and PKD activity codes for a given NIP. Access is free, but you have to apply for a key. The buyer then only enters the NIP and the form fills in the rest.

  • What is the difference between the Polish VAT white list and VIES?

    The white list is the VAT taxpayer register kept by the Head of the National Revenue Administration, used to check the status and bank accounts of Polish businesses. VIES is the European Commission's system for validating the EU VAT numbers of companies in other member states. The first is for domestic transactions, the second for intra-EU ones.

  • Do business accounts in a B2B store need manual approval?

    Not always. Automatic approval speeds up the first order when VAT ID verification is enough to grant standard terms, while manual approval gives the sales rep control over pricing and credit limits. A mixed model is common: the system lets buyers in on standard terms and a person signs off individual ones.
