​​​​​​Follow these steps to ensure the dealing number is correctly validated:

• ​Do not insert spaces or any non-alphanumeric characters. 
• General law or non-TOLD based dealing (a Land Titles Office (LTO) dealing sticker number)
  The dealing number must be formatted as one alphabetic character in the range A-L, followed by 1 to 6 digits inserted immediately adjacent to each other (no spaces).
  
• Dealings generated in TOLD:
  The dealing number must be in the format of one alphabetic character in the range M-Z, followed by 6 digits inserted immediately adjacent to each other (no spaces).  
• A TOLD dealing number must refer to a valid dealing generated in the LTO/TOLD system.​​​

A dealing number that relates to more than one transaction​

• ​TRO now allows for the same dealing number to be used in more than one tr​ansaction. This would occur typically where a dealing is transferring a life interest and remainder interest. 
• The Titles referred to in each transaction need to be identical, and TRO will validate this on submission/endorsement. Where the properties’ Titles are not identical the submission will not be allowed.​
