All Purchase Orders are identified by a unique Purchase Order number which has the following format:

BB/TXXX

BB is the branch code, T is the Type and XXX is a sequential number.

The types are as follows:

• S: Spectacles, i.e. glazing orders
• L: Lenses ordered separately from the glazing order, e.g. uncuts or remote edged
• F: Frame ordered for a glazing order but from a separate supplier to the workshop
• ST: Stock, i.e. products NOT ordered for a specific patient
• C: Contact lenses

So, a typical order reference might look like this:

CE/C701 – Clarity Eyecare Contact Lens Order #701
