CNO lookup by CNPJ

For a known work, enter its 12-digit CNO number. To research a company, use its complete CNPJ. The search includes links under the same company root and identifies previous links. To find works in an area, select a municipality and state. Then filter by area, type and status. Start with a few filters so that you can understand the result. Each page shows up to 20 records. Use the next page to continue. Check the source date before comparing records or using the information for a commercial decision.

Federal Revenue maintains the National Construction Registry. It records construction works and their responsible parties. The CNO number identifies the work; the CNPJ identifies a linked company. These identifiers serve different purposes. Radar can show location, area, construction type, category, dates and status. An empty field means that the information is unavailable in the consulted snapshot. Do not use a registry record as evidence of physical completion, a municipal permit, tax compliance or paid contributions. Each of those checks requires its own documents and sources.

CNO took the place of the INSS-specific register for construction works. Federal Revenue provides a procedure to register a work in CNO from its CEI registration. If you manage an older work, check its registration through the official service first. Radar's public lookup does not register, migrate or edit works. It searches an open-data file that has already been published. If a work is missing, check its number and the source date. Absence from this snapshot does not prove that the work was never registered.

To obtain your work's official certificate, open Federal Revenue's CNO lookup service. Sign in to its authenticated environment with your gov.br account and select a work you are authorized to access. Use the registration and status certificate option on the lookup page. Check the document before sharing it. Access depends on the relationship or representation recognized by Federal Revenue. Radar does not ask for your password, sign in to e-CAC or issue a document on behalf of the authority.

Authenticated access and public research have different coverage. In the official service, access to a work depends on the caller's relationship to it. To research another company, Radar uses the public CNO file. This subset contains only works with a company as the responsible party. Works registered to individuals are excluded. When a name or address contains personal information, the source applies the product's masks. Use the source date to understand when the record applies. Public research does not open restricted company account data or replace authorization.

A work can be active, suspended, stopped, closed or void in the registry. That status describes the work's record, not the company's financial condition. Check the responsible party's role and the available dates too. A company may have been responsible in the past or may share responsibility with another company. Previous links are identified and can include an end date. The area is the value recorded by the source, with its unit. A larger area does not prove revenue. An active work does not guarantee a sale, and a closed work does not prove paid debt.

After checking the filters, save the search or download the current page as CSV. That file contains the page's results, not the entire database. To receive company changes, use CNPJ monitoring and check the available coverage before purchasing a paid feature. An alert depends on a valid source update. If the official file fails or is incomplete, the lookup retains the last valid snapshot and reports its update state. Check the reference and dates to distinguish an unchanged work from a database that has not yet received an update.
