# Bitcoin - Legacy and Segwit Addresses

There are four most common types of Bitcoin address formats:

1. **P2PKH** addresses that begin with the number **"1"**\
   **Example:** *1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2*<br>
2. **P2SH** addresses starting with the number **"3"**\
   **Example:** *3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy*<br>
3. **Bech32** addresses, also known as "bc1 addresses" starting with **"bc1"**\
   **Example:** *bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq* \
   Bech32 is supported by most software and hardware wallets, but only a few exchange platforms. Bech32 is more efficient with block space.
4. **Taproot (P2TR)** addresses, also called Taproot or Bech32m, are the latest and most advanced format in Bitcoin. These addresses are case-insensitive and begin with bc1p. They improve scalability, flexibility, privacy, and security, but they are opt-in and not yet commonly supported, much like SegWit. \
   **Example:** *bc1p5d7rjq7g6r4jdyhzks9smlaqtedr4dekq08ge8ztwac72sfr9rusxg3297*&#x20;
