Hello! Nameuser, Allow me to provide the information you need about the character limit when setting those particular accounts you mentioned.
When you create an account, you can enter letters, numbers, and special characters in the Account name field. The maximum number of characters you can enter is 31.
I also recommend checking this article for tips about the maximum number of characters you can enter in each field: Character limitations for fields in QuickBooks.
If you have questions about the character limit for other fields, please notify me below. I'll be around to help you anytime.
