# Input OTP: Letters and numbers

> `validationType="alphanumeric"` accepts recovery and invite codes, and `normalizeValue` upper-cases them as they are typed or pasted.

Example: https://hextaui.com/docs/input-otp/examples/alphanumeric
Component docs: https://hextaui.com/docs/input-otp.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/input-otp-alphanumeric.json
```

This adds `components/examples/input-otp/alphanumeric.tsx` with the Input OTP component and the HextaUI theme tokens.

## Source

```tsx title="components/examples/input-otp/alphanumeric.tsx"
"use client"

import {
  InputOTP,
  InputOTPGroup,
  InputOTPSeparator,
  InputOTPSlot,
} from "@/components/ui/input-otp"

export function InputOTPAlphanumeric() {
  return (
    <InputOTP
      length={8}
      validationType="alphanumeric"
      normalizeValue={(value) => value.toUpperCase()}
      aria-label="Recovery code"
    >
      <InputOTPGroup>
        <InputOTPSlot />
        <InputOTPSlot />
        <InputOTPSlot />
        <InputOTPSlot />
      </InputOTPGroup>
      <InputOTPSeparator />
      <InputOTPGroup>

        <InputOTPSlot />
        <InputOTPSlot />
