Householder Bulk Mailing Form Numbers

The Post Office began distributing forms for affixing stamps for bulk mailing of householder material in 1924. Since these bulk mailing forms were new the early versions referenced the specific section of the postal guide which covered householder bulk mailing. Three types of forms were produced depending on how the delivery was being made.

7P  - Letter Carriers Walk
8P  - Rural Routes
9P  - Post Office Box Holders

Bilingual forms were also produced which included the marking "1/2" before the letter P in the form number ( e.g. 7 1/2 P. -100,000 - 17-5-24)

At some point in the 1930s the three forms were combined into a multi-use 7P form with three check boxes and the 8P and 9P forms were discontinued.

The following list of forms is not complete and will be updated as new information becomes available. Reporting of new form numbers with a confirming scan would be very much appreciated.
