A pair of improved reusable routing pouches, or envelopes, are disclosed. The first routing pouch includes a single address block made of erasable material which can be covered by a transparent portion of the pouch closure flap. Addresses can be easily written and then erased by wiping so that the routing pouch can be reused indefinitely. The transparent portion of the closure flap covers the written address so that it will not smear or smudge during transit. The second routing pouch has a conventional series of consecutive address blocks printed on its surface, but is made of a material that is erasable by adhesive removal. After all the spaces have been filled in, an adhesive coated roller is roller over the pouch to remove the addresses and ready the pouch for reuse. A variation of the second routing pouch is erased by wiping with a cloth or sponge impregnated with a solvent.
