France-Belgium border postage

The entire eastern boundary of the Department Nord runs along the Belgian border. Long before the introduction of the postage stamp, there was a preferential rate known as the border rate. It was the postal convention of 27 April 1849 between Belgium and France that definitively set the rules for the border rate. A letter posted in a French post office, whether franked or not, to a Belgian town whose post office is located within a maximum of 30 km (in a straight line), will benefit from a lower rate than a letter sent to all other Belgian post offices.

The rate is set at 20 c for a single letter (up to 7.5g).

Letter from VALENCIENNES to PERUWELZ franked at 20 c (Convention of 1/04/1858). PD stamp meaning "Paid to destination".

On 27 February 1865, a new agreement was signed, but the terms and conditions of the border port remained the same.
