Ensure your MBI is formatted correctly using the following details:

  1. The MBI must have 11 characters
  2. The MBI must be unique
  3. The MBI must be in a specific format:
    1. The MBI’s 2nd, 5th, 8th, and 9th characters will always be a letter.
    2. Characters 1, 4, 7, 10, and 11 will always be a number.
    3. The 3rd and 6th characters will be a letter or a number.
    4. The dashes aren’t used as part of the MBI. They won’t be entered into computer systems or used in file formats.
