A username containing the 26 letters of the alphabet (upper and lower case) and Arabic numbers (0-9) is an alphanumeric username. Many programs may often allow users to use the underscore (_) as a character, but the first character will not usually be used as an underscore.

As such, examples are:
Johnsmith
JohnSmith7
JOHNSMITH
John_Smith
4_JoHn_SmItH
J_o_h_n

The only aspect that can be misleading is whether Punctuation Marks and Special Characters are not used in the Alphabet being used; and, assuming English is the only Alphabet to be used and Decimal is the only number system to be used.
