Shall not be assigned to an employer in operations described by another classification unless the operations subject to Code 8800 are conducted as a separate and distinct business.

Code 8800 applies to employers that prepare mailing lists and arrange in addressing and mailing material with respect to such lists.   Such businesses have employees who accumulate names and assign them to specific mailing lists in addition to addressing and mailing material such as but not limited to, newspapers, magazines, letters and circulars.  The incidental printing of the material to be mailed is included.   

This classification includes letter service shops and employers that receive outgoing mail from their customers and sort it by zip code.  Once sorted, the mail is delivered by the employer to the post office.  These operations may have large computer data centers where the mailing list is manipulated to eliminate duplicate records, append change of address information, standardize the address to meet postal requirements, add information to aid in delivery (bar code or zip + 4), and finally sort the records in postal sequence.  Once manipulated, the mailing list may also be used to print personalized letters and envelopes on high-speed laser printers.
