Size of various Battle.net entities:
| Item |
Max. Length (bytes) |
Additional Notes |
| Username |
15 |
Appended characters to enforce unique usernames (ie, #2) can increase the length of a username by 3 characters.
In addition, Diablo II can have very long usernames, due to characters names/realms. The format is: "Character@Realm*Username@Realm"
The lengths for these are: [15]@[6]*[18]@[6]. This results in a maximum possible username length, as recieved from Battle.net, of 48 characters.
Official Blizzard clients assign a 64-character variable for usernames, so the use of a variable of at least that length is advisable for future
compatibility.
When creating an account, any username longer than 15 characters is truncated.

This is the maximum for game clients. Chat clients can recieve up to 255 bytes of chat text. This includes the null terminator. Longer text is truncated. |
Data types:
All numeric Battle.net types are little-endian. Battle.net uses the following types:
- String - Null terminated character array
- DWORD - 32 bit unsigned integer
- Word - 16 bit unsigned integer
- Byte - 8 bit unsigned integer
- FILETIME - A Windows struct
Some data which may at first appear to be strings are in fact DWORDS - game & platform codes, for example. #4

Sending a CrLf (Ascii Character 13) in a chat message will get you disconnected.
