Brazil CNPJ Lookup — Company Status, CNAE & Address

Give it a list of Brazilian CNPJ numbers — in any format, including the new alphanumeric ones — and get one clean row per company: legal name, trade name, registration status, size, main and secondary activities (CNAE), address, opening date and share capital, from the Receita Federal's open CNPJ data. $1 per 1,000 companies, no login, no API key. The default pace is 20 lookups a minute (about 3 seconds per company); raise Max requests per minute up to 60 for bigger lists.

Run it again — or put it on a monthly schedule — and every row also tells you what changed since the last run: statusChanged, the previousStatus (for example Ativa to Baixada) and a changedFields list that names what moved (status, size, address, activity…). The register is republished about once a month, so changes show up at that rhythm, not day by day.

What you get

Field	What it is
cnpj, cnpjFormatted, isHeadquarters	the 14-character number, the usual 19.131.243/0001-97 form, and true for a head office (matriz) or false for a branch (filial)
legalName, tradeName	razão social and nome fantasia. tradeName is null when the company has none; both are null for sole proprietors (see Notes)
status, isActive, statusReason, statusDate	situação cadastral as published (for example Ativa, Inapta, Baixada), true when it is Ativa, the reason and the date of that status
openingDate, legalNature, size, shareCapital	start of activity, natureza jurídica, porte (for example Microempresa (ME), Demais) and share capital in reais
mainActivityCode, mainActivityCodeFormatted, mainActivityDescription	the main CNAE: 7 digits (9430800), the printed form (9430-8/00) and its description
secondaryActivities	the list of secondary CNAEs, each { code, description }
address, street, number, complement, district, city, state, zip	where the establishment is registered: one printed line, and the parts
simplesNacional, simplesSince, mei, meiSince	Simples Nacional and MEI options when the register holds a record for the company
soleProprietor	true for one-person registrations (Empresário Individual, MEI, a one-lawyer firm…), which are returned without names, street or ZIP
isNew, statusChanged, previousStatus, previousStatusDate, changedFields, previousObservedAt	the change since your previous run (isNew is true and the others null on the first run)
type, input, observedAt	company (or error), the number as you typed it, and when it was read

Error rows (type: "error") carry input, cnpj (when the number is valid) and a message: a number whose check digits are wrong, or one that is not in the published data.

Run it again and again

• On a schedule — save your input as a task and add a Schedule: the same CNPJs every month. Send each run to Google Sheets, Slack or email with an integration on the task.
• Watch for changes — Keep the same input on the schedule. Each run is its own dataset with the date it ran, so the series builds up run by run and you can compare one day with the last.
• In bulk — Put every number in CNPJ numbers in one run.

Use it for

• Checking a customer, supplier or lead list — is the CNPJ still Ativa, or has it become Inapta or Baixada?
• Enriching B2B lead lists — add industry (CNAE), size, city and state, opening date and share capital to a list of CNPJs
• Watching a portfolio — schedule it monthly and filter on statusChanged = true to see which companies moved

Input

{ "cnpjs": ["19131243000197", "33.000.167/0001-01", "00000000000191"], "maxRequestsPerMinute": 20 }

CNPJs can be written with or without dots, slash and dash, one per line. The two check digits are verified first, so a typo costs nothing and comes back as a free error row. Numbers that a spreadsheet shortened by dropping leading zeros (191 for 00000000000191) are restored when the check digits then fit.

What the Actor remembered about each CNPJ (status and the other watched values) is kept in a named key-value store, brazil-cnpj-status, in your Apify account, so the second run of the same Actor already shows changes. Schedule it (Apify → Schedules) to keep the history going.

Pricing

$1.00 per 1,000 companies, plus $0.01 per run. Error rows (invalid or unknown CNPJs) are free. The $0.01 run-start fee is the one charge every run pays, even one that returns nothing.

Notes

• Source: the Receita Federal's public CNPJ base, read through the free OpenCNPJ API (api.opencnpj.org). Its documentation says it is free for commercial use and that it republishes the base about once a month. The data can be out of date or incomplete in the ways the Receita's own file is.
• Companies only. Partners (quadro societário) are never read, and no email addresses or phone numbers are returned: the email in the register can be the company's accountant rather than the company, so contacts are dropped rather than guessed.
• Sole proprietors (Empresário Individual, MEI, rural producers, election candidates, one-lawyer firms and other one-person registrations) are registered under the person's own name. For these rows legalName, tradeName, street, number, complement and zip are null and soleProprietor is true. Status, dates, activities, size, district, city and state are still returned. A list of small businesses will contain many of them.
• Other company names are published as the register has them. A company's legal name can contain its owner's name (for example a one-partner Ltda named after the partner); only the one-person registration types above are withheld.
• Text is in Portuguese as the Receita publishes it (status, statusReason, legalNature, size, activity descriptions). status values include Ativa, Suspensa, Inapta, Baixada and Nula.
• Some fields are null by condition: tradeName when the company has no trade name; statusDate when the register gives no date; simplesNacional, simplesSince, mei and meiSince when the register holds no Simples/MEI record for the company (null means no record, not "no"); mainActivityCode, mainActivityCodeFormatted and mainActivityDescription when the register only holds its "activity not informed" placeholder (seen on closed one-person registrations), which is dropped rather than shown as a real CNAE; secondaryActivities is an empty list when there are none. isNew is true and previousStatus, previousStatusDate, statusChanged, changedFields and previousObservedAt are null the first time a CNPJ is seen.
• changedFields can contain status, statusDate, statusReason, legalName, tradeName, legalNature, size, shareCapital, mainActivityCode, address, isHeadquarters, simplesNacional and mei. statusChanged is true when status or statusDate moved.
• A very new CNPJ may not be in the published data yet and comes back as an error row ("Not in the published Receita Federal data").
• Speed: the default of 20 requests per minute is about 3 seconds per company; the maximum of 60 is about 1 second per company (measured on 9 Oct 2026: 6 lookups took 15 seconds at 20 per minute, 29 lookups took 34 seconds at 60 per minute). If the source answers "too many requests" the Actor waits and retries twice, and it stops asking after five lookups in a row fail, with the remaining numbers returned as free error rows.
• You are responsible for how you use the data, including data-protection rules such as the LGPD.

For AI agents

{"cnpjs": ["19131243000197"]} returns one row for that CNPJ with its status, size, main activity and address. Rows have type: company or error. To monitor a list, run the same input on a schedule and keep rows where statusChanged is true; previousStatus and status show the move.
