With the adoption of a new Swiss Federal Constitution on September 12, 1848, the days of the Cantonal stamps were numbered. The Constitution provided that postal control belonged to the Confederation. Of course, establishment of a Federal Post Office could not be instantaneously achieved and provisions were made for the continued operation of the Cantonal postal services while the Federal systems were organized. During this period, the Cantons of Zürich and Geneva continued to issue stamps, placing on them the Federal cross, to indicate the centralization of the postal service.

Finally, in April 1850, the Federal Council authorized the production, distribution, and use of Federal postage stamps for local mail in 36 Swiss towns. The rates were 2 1/2 rappen for the first ounce, 5 rappen for up to two ounces, and 10 rappen for up to 4 ounces, all for local delivery. Stamps were produced only in 2-1/2 rappen denominations so heavier letters required multiple stamps.
