# Rules for Study Names

Study names must be between 1 and 32 characters in length, and must be unique.

Note: Although the case of your study name is retained, case differences alone do not make a study name unique. For example, if you previously registered “MYSTUDY”, you cannot create another study named “MyStudy” until you delete the “MYSTUDY” variant. Also note that while both spaces ( ) and underscores (_) are accepted in a study name, they are considered equivalent when determining uniqueness. For example, if you previously registered “My Study”, you cannot create another study named “My_Study” until you delete the “My Study” variant.

Acceptable Characters

The first character through the second-last character can consist of:

| • | letters: A-Z a-z

| • | numbers: 0-9

| • | spaces (blanks)

| • | special: @ # - _ + .

The final character can be any of these, except for a period (.).

Caution: You should assume that characters not listed above are potentially problematic. Use them at your own risk.
