IPN, the individual tax number, is the everyday name for the tax number officially called the taxpayer registration card number, or taxpayer ID number (RNOKPP). The easiest way to see your number is in the Diia app, and the paper card can be supplemented with an electronic one, an e-Card with a QR code. Both options are free. Below: how to find your number online, how to get the card, and what to do if you do not have a number yet or your data does not match. Data checked on 21 October 2026.
IPN and RNOKPP Are the Same Thing
According to the Diia state services guide, identification numbers issued before the Tax Code took effect are considered valid in all cases where the RNOKPP is used. So the old “identification code” on your card and today’s tax number are one and the same number.
The State Register of Individual Taxpayers (DRFO) is maintained by the State Tax Service, or DPS (clause 70.1 of the Tax Code, version of 17 September 2026). You need the number, among other things, when you are paid income, sign contracts concerning taxable items or open a bank account (clause 70.12). You will also need it to register as a sole proprietor (FOP): see our article how to register a FOP online through Diia. A person who has refused a number for religious reasons and has a note about this in their passport is registered by passport series and number.
Option 1: View Your Number in Diia
According to the Paperless guide from the Ministry of Digital Transformation (Mintsyfry), the taxpayer card appears in the app automatically after you log in. The number is not visible right away: the app sends a request to the DPS register and checks your full name, date of birth and RNOKPP. If everything matches, the document gets a “Verified” mark. The check takes from 3 to 20 minutes and is repeated automatically every 30 days.
This check is also provided for by the Ministry of Finance regulation on registration in the DRFO (Order No. 822, version of 15 May 2026): the number can be presented as part of an e-passport, an e-passport for travel abroad or an e-birth certificate, or separately, as an electronic copy of the document in Diia, if the data has been confirmed through the DRFO (clause 11 of Section III). The taxpayer card is among the documents whose validity can be checked in Diia and whose digital copies you can get, as stated in the Diia help section.
Option 2: The Taxpayer e-Card
If you need the document itself, you can order an e-Card in the app: a PDF with a QR code that has the same legal force as the paper card (Diia tax services page). According to a Diia news item of 4 June 2026, more than 62,500 people used the service in its first two weeks. The procedure is as follows:
- Log in to the Diia app.
- Select “Services” → “Tax services” → “Taxpayer e-Card.”
- Specify who the card is for: yourself or a child. Enter the tax number if required.
- Enter or confirm your contact details.
- Check the application and sign it with “Diia.Signature.”
- Download the e-Card within 24 hours.
The conditions are: you are at least 14 years old, the app has a digital ID card or international passport, you already have an RNOKPP and a declared or registered place of residence. When you order, an application on form 5DR is generated, so the tax authority checks and, if necessary, updates your data in the register, for example after a change of surname or address.
Option 3: The Tax Authority’s Electronic Cabinet
The “EC for citizens” mode of the Electronic Cabinet has two forms. Registration card 1DR is for registration in the DRFO if the person does not have a number yet. Application 5DR is for making changes to the register. In the form you choose the taxpayer service center where you will pick up the paper card, attach scanned copies of documents (for an ID card, both sides and a document on your place of residence) and sign with a qualified electronic signature. According to the state services guide, the online application is submitted through cabinet.tax.gov.ua, and the result, the taxpayer card, is collected in person or through a legal representative.
If You Do Not Have a Number Yet
- Adults. Submit registration card 1DR through the Electronic Cabinet or in person at the tax office. Citizens of Ukraine can apply to the supervisory authority at their tax address or to any other one.
- Children up to and including age 17. One of the parents can get a number in Diia: “Services” → “Tax services” → “Child’s tax number.” The parent’s RNOKPP must be verified, and the ID card or international passport and the child’s birth certificate must be shown in the app. For children aged 14–17, an ID card is mandatory. Only the parent the child lives with can apply; this service is not available to guardians in the app.
- Teenagers aged 14 or older without an ID card. Diia recommends the ID-14 combined service: the first passport and the tax number are issued at the same time.
- People abroad. Documents for registration in the DRFO can also be submitted through the “e-Consul” system (clause 4 of Section III of Regulation No. 822). For children born abroad, Diia advises contacting a consulate.

If It Does Not Work
- The number “requires verification.” According to Paperless, the most common reason is a full name entered incorrectly in the register or an inaccuracy in your bank data. First contact your bank to check the data, and if everything is correct there, contact the tax office at your place of registration.
- The surname in the civil registry record does not match your passport. In that case Diia cannot confirm your identity, and the e-Card will not be available. You need to contact the State Migration Service (DMS) and get a document with up-to-date data.
- Your data has changed. The tax office must be notified of changes to the data in your registration card within a month (clause 70.7 of the Tax Code). To do this, submit application 5DR or order an e-Card.
- You need the number in your passport booklet. At your request, the tax office at your place of residence can enter the RNOKPP in your passport (on the seventh, eighth or ninth page).
Other people’s numbers are not in open data. Even the Unified State Register of legal entities and FOPs, whose information is open, does not publish taxpayer registration card numbers or passport data (Part 1 of Article 11 of Law No. 755-IV). Websites that promise to “find an IPN by surname” are a reason to be wary. Do not enter your data on third-party sites and do not send photos of your documents to strangers: for common schemes, read our article on bank card fraud.
Frequently Asked Questions
Are the IPN and the RNOKPP the same thing?
Yes. Identification numbers issued before the Tax Code took effect are considered valid for all uses of the RNOKPP. The official name now is the taxpayer registration card number.
Does the e-Card have the same force as the paper card?
Yes. According to Diia, the taxpayer card in electronic form has the same legal force; both documents exist in parallel.
How can I find out my IPN without a smartphone?
Go to the tax office with an identity document: the taxpayer card will be issued free of charge, usually within 3 business days. If you have a qualified electronic signature, you can apply through the Electronic Cabinet and pick up the card at the taxpayer service center you choose.
At what age can I order an e-Card myself?
From age 14. For children under 14, the card is ordered by their parents in the Diia app.
Do I have to tell the tax office about a new surname?
Yes. The tax office is notified of changes to the registration card data within a month (clause 70.7 of the Tax Code). A convenient way is to order an e-Card in Diia: when you order it, an application on form 5DR is generated, and the tax office updates the data in the register.
