    How do I find a company's registration number in Argentina?

    Search the company's name on ARCA / IGJ at https://www.arca.gob.ar/. The result page shows its registration number — the same identifier that appears on invoices, contracts, and government filings.

    Step-by-step

    1. 1

      Open ARCA / IGJ

      Navigate to https://www.arca.gob.ar/.

    2. 2

      Search by company name

      Type the exact trading or legal name. Partial matches usually work; add the city if the name is common.

    3. 3

      Copy the registration number

      The registration number is displayed at the top of the entity profile. It is the authoritative ID for cross-referencing.

    4. 4

      Confirm it's the right entity

      Check the registered address and incorporation date to be sure you have the correct legal entity, especially for groups with similarly named subsidiaries.

    Argentina: choosing and checking the right record

    Choose the correct source
    Use ARCA, formerly AFIP, for the exact CUIT tax-registration check. For company registration, select IGJ for CABA or the relevant provincial register. A national tax result and a local commercial-register file answer different questions.
    Confirm the entity
    Keep the 11-digit CUIT together with the legal name and incorporation jurisdiction. Compare the entity on the contract rather than a trading label, and distinguish a fiscal address from a registered office where both are supplied.

    Frequently asked questions

    Where is a Argentina company's registration number published?

    Look for the identifier on the entity's record or available extract in ARCA / IGJ (https://www.arca.gob.ar/). Compare it with the counterparty's documentation; publication requirements and identifier labels vary by jurisdiction.

    Is looking up a Argentina registration number free?

    LemReveal's basic lookup is free. Check ARCA / IGJ's current access rules: an official portal can require an account, charge for searches or restrict particular documents.

    What is a CUIT?

    CUIT (Clave Única de Identificación Tributaria) is Argentina's 11-digit tax identification number. For companies, the format is XX-XXXXXXXX-X. The first two digits indicate entity type (30 for companies, 33 for branches, 34 for non-profits).

    Is the Argentina company register free to search?

    Yes. Basic company lookups on the ARCA / IGJ are free — you can search by company name or registration number, view legal status, registered address and (usually) directors at no cost. Some jurisdictions charge a small fee only for downloading full filed documents.

    What is the official Argentina business registry?

    The ARCA / IGJ is the official public register of companies incorporated in Argentina. It is operated by the government and is the primary source cited on this page — https://www.arca.gob.ar/.

    Where do I find a Argentina company's registration number?

    Every registered Argentina entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its ARCA / IGJ record.

    Is a Argentina registration number the same as a VAT number?

    No. The registration number is the identifier issued by the ARCA / IGJ when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
