On 1/17/77, a check was made with several laundries that specialize in martinizing in the Seattle area, and it was learned that laundry tickets are customarily stapled to trousers and other items as they are received from the customer for cleaning. The number and letters on these tickets correspond with a code which is a sequential numbering system. The first character in the code is an alphabetic letter and the second character in the code is a number, ranging from 1 to 10,000.
When a customer brings in an item for cleaning, such as a pair of trousers, he fills out a cleaning form requesting cleaning and putting his name on the form. The date of pickup and the cross reference number also appears on this form. The number on the form could be A-1 through 10,000 and a corresponding tag would then be stapled to the trousers with that number A-1 through 10,000, so that the trousers could be located in the event the customer does not show up to claim his cleaning items.
Most laundries vary the first letter from A-1 through 10,000 to B-1 through 10,000, etc., until the end of the year, at which time they normally start over again with A-1 through 10,000; however, this is not a hard and fast rule and with just a number such as found on the trousers in this case, A-317, it would be impossible to determine who the customer was who had the trousers cleaned. It might be possible in some cleaning establishments to determine the customer if the trousers were recently cleaned by checking past ticket [handwritten: Sub 858]
