Whether you’re creating an account on a website, applying for a job, or simply filling out a registration form, you’re bound to come across various error messages. One such common error is the ‘Last Name is Not in Expected Format’.

Encountered ‘Last name is not in expected format’? This article discusses the common causes of this error and a few ways to fix it.


What causes this error?

When you encounter the message ‘Last Name is Not in Expected Format’, it typically means that the last name you’ve entered does not meet the specific format or requirements set by the online system or database.

Common causes

  • Special Characters: Many online forms restrict using special characters or symbols in the last name field. If your last name contains characters such as @, #, $, or any non-alphabetical characters, the error may occur.
  • Length Limitations: Some platforms impose character limits for the last name field. If your last name is too long, you might encounter this error.
  • Blank Spaces: Extra spaces at the beginning or end of the last name can trigger this error.
  • Invalid Characters: Uncommon diacritical marks, non-standard symbols, or punctuation marks may lead to errors.

  • Remove Special Characters: The first step is to check your last name for any special characters. If you find any, remove them and try again.
  • Check Length: Ensure that your last name does not exceed the character limit, if there is one. You may need to abbreviate or omit part of your last name if it’s too long.
  • Eliminate Blank Spaces: Double-check for any extra spaces at the beginning or end of your last name. Trim them to make sure it’s a continuous string.
  • Use Standard Characters: Stick to standard alphabetic characters in your last name to avoid the error. If you have diacritical marks, consider using their standard counterparts (e.g., replace “é” with “e”).
  • Contact Support: If none of the above solutions work, don’t hesitate to contact customer support for the platform in question. They can guide you on how to resolve the issue or provide alternatives.
