What a SteamID64 is
A 17-digit number and the format Steam itself uses everywhere internally. It is the account ID added to a fixed base of 76561197960265728, which is why every individual account's SteamID64 starts with 7656119.
Every endpoint of the Steam Web API takes this format, and it is what you see in a profile URL of the form steamcommunity.com/profiles/76561198012345678. If you are writing anything that talks to Steam programmatically, this is the format you store.
What a Account ID is
The bare 32-bit account number underneath every other format. Strip away the base offset and the textual wrapping and this is what remains — the actual identity.
The Dota 2 match history API uses it, several match-history and stats sites key on it, and it is the number shown in a Steam friend invite code. It is also the value you want if you are storing IDs compactly, since it fits in 32 bits.
Converting more than one ID
This page handles a single ID at a time. To convert a whole list at once — a ban file, an admin config, a spreadsheet column — use the bulk converter, which accepts mixed formats and custom profile URLs in the same paste.
