# Pix key types (/en/docs/pix-processamento/pix-key-types)
The PayZu API accepts the 5 official Pix key types defined by
Bacen. The `pixType` field indicates which type is being used, and the
format of `pixKey` changes according to each one.
## Available types [#available-types]
| Type | Description | Format | Example |
| ------- | ---------------------------- | ------------------------------------- | -------------------------------------- |
| `cpf` | Holder's CPF (individual) | 11 numeric digits, no formatting | `12345678901` |
| `cnpj` | Holder's CNPJ (legal entity) | 14 numeric digits, no formatting | `12345678901234` |
| `phone` | Mobile phone | E.164 standard with country code (55) | `5511987654321` |
| `email` | Email address | Valid email format | `user@domain.com` |
| `evp` | Random key | UUID v4 (issued by Bacen) | `123e4567-e89b-12d3-a456-426655440000` |
## Validation [#validation]
The API validates the `pixKey` format automatically according to the
`pixType` provided. If the format does not match, it returns `400 Bad Request` before
sending the operation to Bacen.
Before making a Pix payment, we recommend looking up the key in DICT to
validate that it exists and confirm the holder. See
[DICT lookup](/docs/pix-processamento/best-practices/dict).
