Is Portuguese Brazil's Only Official Language?

Two legal layers sit behind this question and are easy to mix up: one federal, one municipal. Whether people speak English is a third question, and a different guide.

Article 13 settles the national question in one line

The Constitution spends one sentence on it: "A língua portuguesa é o idioma oficial da República Federativa do Brasil" — Portuguese is the official language of the Federative Republic of Brazil. In the text Planalto publishes, the article carries no amendment note and no repeal mark. Checked on September 16, 2026.

Other languages do appear, and where matters. Article 210, on schooling, guarantees Indigenous communities "a utilização de suas línguas maternas e processos próprios de aprendizagem" in primary education — delivered, the same paragraph says, in Portuguese. A right inside a school system, not a second official language. Nothing below the Constitution creates one either, and what exists there is much less known.

99 municipalities have made a second language co-official

Since 2002, municipalities have passed laws declaring another language co-official inside their own boundary. The count comes from the Brazilian Repository of Linguistic Legislation (RBLL), kept by the institute IPOL: its dashboard, version dated August 2, 2026, publishes 132 indexed acts, 107 co-officialising laws, 99 municipalities and 63 languages. Three states did it statewide — Amazonas, Roraima and Amapá.

Those figures are the repository's own. Every breakdown below is ours, counted from its records on that date — one municipality once per language, amending laws ignored. Counted that way 71 are southern: 52 in Rio Grande do Sul, 15 in Santa Catarina, 4 in Paraná. Of those, 43 passed their first such law in 2022 or later, 15 in 2025 alone; the oldest is Monte Belo do Sul's, from 2004, two years after the practice began 4,000 km north.

Which languages, and why those ones

German and Italian are on the list, but they are not the story. Counting southern municipalities:

Xokleng is the southern outlier: an Indigenous language, co-officialised with Italian and German in José Boiteux by Law 1,299 of March 20, 2025. Outside the south the picture inverts — most co-officialised languages there are Indigenous, from Nheengatu in Amazonas to Terena in Mato Grosso do Sul, plus four sign languages.

The southern list follows the colonies. IBGE publishes a table — reproduced from a 1980 study by Emílio Willems, not collected by the institute — of where each settlement's colonists came from: São Leopoldo, 1824, from the Hunsrück; Blumenau, 1850, from Pomerania. That is why Pomerode has Pomeranian rather than standard German.

What these laws actually do — permit, or oblige

Read side by side, the laws stop agreeing with each other.

In Bento Gonçalves, Rio Grande do Sul, Law 6,109/2016 opens its article 2 with "permite ao Município", permits the municipality to: a power, not a duty, over fourteen items including teaching Talian in schools. The duties come next, in imperative verbs — the municipality produzirá public documentation, and basic services serão prestados in the official language, in Talian, or bilingually. Chopinzinho, in Paraná, opens the opposite way nine years later: Law 4,154 of October 1, 2025 says "Compete ao Município", it falls to the municipality.

The strongest version is also the oldest. São Gabriel da Cachoeira, in Amazonas, co-officialised Nheengatu, Tukano and Baniwa by Law 145 of December 11, 2002, the first such law in Brazil. Its article 2 says the status "obriga o município", obliges the municipality, and the first paragraph says to what: "A prestar os serviços públicos básicos de atendimento ao público nas repartições públicas na língua oficial e nas três línguas co-oficiais, oralmente e por escrito." Article 3 makes administrative acts valid in any of them; article 4 bars discrimination over which one you use. Law 210/2006 ratified it; the repository records no repeal.

So co-official is not one status: the range runs from a permission to an enforceable duty.

What it does not mean for a foreigner

That range is why the answer here is conditional. In the southern laws read for this guide, the statutes rule themselves out.

Itá's 2026 law answers it in its own article 3: co-officialisation there "possui caráter cultural e patrimonial, não afastando a primazia da língua portuguesa como oficial" — cultural and heritage in character, not displacing the primacy of Portuguese. Serafina Corrêa's Law 2,615/2009, in the consolidated text — amended in 2025 by Law 4,397, which struck "(Vêneto Brasileiro)" from the name — does it by sequence: article 1 states that Portuguese is Brazil's official language, and only its single paragraph adds Talian. Blumenau's Law 9,522/2024 is recorded as adopting German "como oficial, complementar e secundário ao idioma Português".

São Gabriel da Cachoeira is the real counter-example — but its duty binds its own counters, nothing else. Everything federal is unchanged: your CPF and how to get one, visa rules, address formats, SIM registration, emergency numbers, the apostille and sworn translation a foreign document needs. What changes locally is the time zone and the holiday calendar — not the language of the counter.

Libras is recognised federally, but not made official

Brazilian Sign Language is the other candidate people raise, and the federal statute is precise. Law 10,436/2002, article 1, recognises Libras "como meio legal de comunicação e expressão", with obligations on public bodies to support its use.

That is not officialisation, and the law says so. The single paragraph of article 4 reads: "A Língua Brasileira de Sinais - Libras não poderá substituir a modalidade escrita da língua portuguesa" — it cannot replace written Portuguese. Planalto serves no consolidated version and the text carries no strikethrough. Checked on September 16, 2026.

The municipal layer does not follow the federal one, which is the point of this guide: Miranda, in Mato Grosso do Sul, added Libras to its co-official languages by Law 1,538/2023, alongside Terena Sign Language and Kinikinau.

The federal layer is an inventory, not an official language

The third layer is the easiest to mistake for officialisation. Decree 7,387/2010 created the National Inventory of Linguistic Diversity; its article 3 grants an inventoried language the title of Referência Cultural Brasileira, Brazilian Cultural Reference. Article 7 and its five paragraphs — the commission that examined applications — were repealed by Decree 9,938/2019, and Planalto serves no consolidated page, so live and struck-out text share it. Articles 1 and 3 are intact. Checked on September 16, 2026.

Then a distinction secondary sources get wrong. On IPHAN's sheets, Talian's status field reads "Línguas incluídas no INDL" — included. Hunsrückisch's reads "Línguas aguardando inclusão no INDL" — awaiting inclusion. Chopinzinho's 2025 law even tags its language "(Língua de Referência Cultural Brasileira)", writing the federal title into a municipal statute.

What we could not verify

• Why the repository's total and ours differ by one. Its dashboard publishes 99 municipalities; counting the same records by the creator field gives 100. We could not resolve which record accounts for the gap, so the figure above is theirs.
• Most of the individual laws, one by one. Only the laws named above have an official copy behind them here; the rest of the count comes from the repository's index. That is why the wording about rights is conditional: we know what those statutes say, not what all 99 say.
• How many people speak these languages. No official count exists: the census asks about Indigenous languages spoken at home, not immigration languages, and the IPHAN sheets describe vitality in prose, without a number.
