List of address prefixes

From Bitcoin Wiki

Blockchain-based currencies use encoded strings, which are in a Base58Check encoding with the exception of Bech32 encodings. The encoding includes a prefix (traditionally a single version byte), which affects the leading symbol(s) in the encoded result. The following is a list of some prefixes which are in use in the reference Bitcoin codebase.

Decimal prefix Hex Example use Leading symbol(s) Example
0 00 Pubkey hash (P2PKH address) 1 BTC_Address

Note that private keys for compressed and uncompressed bitcoin public keys use the same version byte. The reason for the compressed form starting with a different character is because a 0x01 byte is appended to the private key before base58 encoding.

The following table shows the leading symbol(s) and address length(s) for 160 bit hashes for each of the possible decimal version values:
