An order number is a unique identifier or code assigned by a trader to track a particular transaction or product. The order number is usually used internally by businesses or organizations to track their own purchases. However, some companies give their customers the order number to track their purchases.
Order numbers appear in alphanumeric format, which includes letters, numbers or both. The alphanumeric code typically provides additional details about a particular order, such as the specific item sold, the location of the purchase, buyer and the date of sale.
When alphanumeric codes appear in the order number, they represent particular characteristics of the order as understood by the management or employees. Companies select their order numbers in a manner that suits their internal tracking systems. Some order numbers consist of more than 30 characters, while others are less than five.
Companies provide the order number to their accounts departments to prove that a particular transaction or purchase is legitimate. Some companies print the order number on their receipts while others send them to their customer’s phone numbers for orders purchased via cellphones. The order number is also used by customers as reference when raising a complaint about a particular product purchased from the company.
