Postage due 1863-1878
Letters circulating in the commune of the post office
On the 1st January 1863 was introduced a franking incentive for the local rates, so that a postage due letter weighing up to 10g cost 15c to the addressee instead of 10c to the sender if it had been franked.
The 10c Chiffre-Taxe therefore became useless. The Administration asked post offices to return them still in stock (circular no. 274 in Monthly Bulletin no. 88, 1862).
1864: Postage due Letter from and to VALENCIENNES.
On 1st September 1871, postal rates changed and a local postage due letter weighing up to 10g cost 25c to the addressee and 15c to the sender if it was franked.
The introduction of the Chiffres-Taxes at 25 c was not immediate. Post offices were therefore asked to use the old 15 c Chiffres-Taxes for their value, or to tax with a pen.
1875: From and to DUNKERQUE postage due.

Letters with insufficient postage
Local letters with insufficient postage were also to be taxed using Chiffres-Taxes, if the tax calculation so allowed.
1872: Letter with insufficient postage at 2 c and taxed at 23 c according to the following calculation:
Postage due for a single letter: 25 c
Postage stamp: 2 c
Amount of tax: 2 c-10 c = 23 c
1871: Letter from LILLE to LILLE with insufficient postage at 10 c. The letter was therefore taxed at 15 c as follows:
Postage due for a single letter: 25 c
Postage stamp: 10 c
Amount of tax: 25 c-10 c = 15 c
It should be noted that on 13 September 1871, the 15 c Chiffres Taxes were still in use at the LILLE post office.
1877: Letter up to 20 g with insufficient franking at 15 c. The rates of 1st 1876 stipulated that such a letter should be franked at 30 c. The 35 c tax is calculated as follows:
Postage due on double letter: 50 c
Postage on the letter: 15 c
Amount of tax: 50 c - 15 c = 35 c
