# CNPJ Alfanumérico

A partir de **julio de 2026**, la Receita Federal de Brasil podrá emitir nuevas inscripciones de CNPJ en un **formato alfanumérico** (letras y números). Las inscripciones existentes **no serán modificadas**.

La **API de CNPJ.ws** ya está preparada para este nuevo formato y acepta consultas utilizando **CNPJ alfanumérico**.

### Cálculo de los dígitos verificadores

El nuevo CNPJ alfanumérico está compuesto por **14 caracteres**, al igual que el actual:

* Los **primeros 12 caracteres** son alfanuméricos
* Los **últimos 2 caracteres** son **dígitos verificadores** numéricos

Los dígitos verificadores se calculan a partir de los primeros doce caracteres en **dos etapas**, utilizando el **módulo 11** y pesos distribuidos de **2 a 9**.

#### Cálculo del primer dígito verificador

Para cada carácter del CNPJ, se debe asignar el valor de la columna **“Valor para el cálculo del dígito verificador”** según la tabla siguiente, o restar **48 al valor ASCII**:

| CNPJ Alfanumérico | Valor ASCII | Valor para el cálculo del DV |
| ----------------- | ----------- | ---------------------------- |
| 0                 | 48          | 0                            |

| Z                 | 90          | 42                           |

Ejemplo:

<table data-full-width="false"><thead><tr><th width="84">CNPJ</th><th width="55">1</th><th width="55">2</th><th width="57">A</th><th width="56">B</th><th width="56">C</th><th width="55">3</th><th width="56">4</th><th width="55">5</th><th width="56">0</th><th width="55">1</th><th width="56">D</th><th width="56">E</th></tr></thead><tbody><tr><td>Valor</td><td>1</td><td>2</td><td>17</td><td>18</td><td>19</td><td>3</td><td>4</td><td>5</td><td>0</td><td>1</td><td>20</td><td>21</td></tr></tbody></table>

Distribuya los pesos de **2 a 9**, de **derecha a izquierda** (reiniciando después del octavo carácter), como se muestra a continuación:

<table data-full-width="false"><thead><tr><th width="84">CNPJ</th><th width="55">1</th><th width="55">2</th><th width="57">A</th><th width="56">B</th><th width="56">C</th><th width="55">3</th><th width="56">4</th><th width="55">5</th><th width="56">0</th><th width="55">1</th><th width="56">D</th><th width="56">E</th></tr></thead><tbody><tr><td>Valor</td><td>1</td><td>2</td><td>17</td><td>18</td><td>19</td><td>3</td><td>4</td><td>5</td><td>0</td><td>1</td><td>20</td><td>21</td></tr><tr><td>Peso</td><td>5</td><td>4</td><td>3</td><td>2</td><td>9</td><td>8</td><td>7</td><td>6</td><td>5</td><td>4</td><td>3</td><td>2</td></tr></tbody></table>

Multiplique el valor por el peso de cada columna y sume todos los resultados:

<table data-full-width="false"><thead><tr><th width="94">CNPJ</th><th width="55">1</th><th width="55">2</th><th width="57">A</th><th width="56">B</th><th width="56">C</th><th width="55">3</th><th width="56">4</th><th width="55">5</th><th width="56">0</th><th width="55">1</th><th width="56">D</th><th width="56">E</th></tr></thead><tbody><tr><td>Valor</td><td>1</td><td>2</td><td>17</td><td>18</td><td>19</td><td>3</td><td>4</td><td>5</td><td>0</td><td>1</td><td>20</td><td>21</td></tr><tr><td>Peso</td><td>5</td><td>4</td><td>3</td><td>2</td><td>9</td><td>8</td><td>7</td><td>6</td><td>5</td><td>4</td><td>3</td><td>2</td></tr><tr><td>Producto</td><td>5</td><td>8</td><td>51</td><td>36</td><td>171</td><td>24</td><td>28</td><td>30</td><td>0</td><td>4</td><td>60</td><td>42</td></tr></tbody></table>

`5 + 8 + 51 + 36 + 171 + 24 +28 + 30 + 0 + 4 + 60 + 42 = 459`

Obtenga el resto de la división de la suma entre **11**.\
Si el resto es **0 o 1**, el primer dígito verificador será **0**.\
De lo contrario, el primer dígito verificador será **11 − resto**.

En este ejemplo:\
Resto de `459 / 11 = 8`, por lo tanto el primer dígito verificador es **3** (resultado de `11−8`) .

#### Cálculo del segundo dígito verificador

Para calcular el segundo dígito verificador, agregue el **primer dígito verificador** al final del CNPJ, formando **13 caracteres**, y repita los mismos pasos utilizados para el primer dígito.

<table data-full-width="false"><thead><tr><th width="95">CNPJ</th><th width="55">1</th><th width="55">2</th><th width="57">A</th><th width="56">B</th><th width="56">C</th><th width="55">3</th><th width="56">4</th><th width="55">5</th><th width="56">0</th><th width="55">1</th><th width="56">D</th><th width="56">E</th><th width="56">3</th></tr></thead><tbody><tr><td>Valor</td><td>1</td><td>2</td><td>17</td><td>18</td><td>19</td><td>3</td><td>4</td><td>5</td><td>0</td><td>1</td><td>20</td><td>21</td><td>3</td></tr><tr><td>Peso</td><td>6</td><td>5</td><td>4</td><td>3</td><td>2</td><td>9</td><td>8</td><td>7</td><td>6</td><td>5</td><td>4</td><td>3</td><td>2</td></tr><tr><td>Producto</td><td>6</td><td>10</td><td>68</td><td>54</td><td>38</td><td>27</td><td>32</td><td>35</td><td>0</td><td>5</td><td>80</td><td>63</td><td>6</td></tr></tbody></table>

`6 + 10 + 68 + 54 + 38 + 27 + 32 + 35 + 0 + 5 + 80 + 63 + 6 = 424`

Resto de `424 / 11 = 6`, por lo tanto el segundo dígito verificador es **5** (resultado de `11 − 6`).

Resultado final: `12.ABC.345/01DE-`<mark style="color:red;">`35`</mark>
