What Does a Bitcoin Address Begin With?

- Non-Native SegWit (P2SH-SegWit): Begins with "3."
Testnet Addresses:
- Native SegWit (Bech32): Begins with "tb1q," "tb1p," or "tb1r."
- Non-Native SegWit (P2SH-SegWit): Begins with "m" or "2."
Legacy Addresses (P2PKH):
- Begins with "1."
Multisignature Addresses:
- m of n Support: Begins with "2," followed by a number to indicate the required number of signatures (e.g., "23" for a 3-of-3 multisignature address).
Unique Characteristics:
- Bitcoin addresses are case-sensitive.
- They can contain a combination of uppercase and lowercase letters, as well as numbers.
- They are typically between 26 and 35 characters long.
Security:

- Keeping private keys (which correspond to Bitcoin addresses) secure is crucial for maintaining funds.
