Most mail from the district of Chalco went through the sub-office of Cuautla (de Morelos). It's actually a bit difficult to find stamps, without sub-number, cancelled in Chalco itself! Corbett estimated that Cuautla used perhaps three times as many stamps as Chalco itself. Something like 60% of the un real stamps were actually sent to sub-offices. Bash found that very few (less than 20), if any at all, of the 4R stamps were used in Chalco, for example. Corbett found a total of 14 4R stamps, 11 of which were cancelled at Cuautla de Morelos. He did not specify where the remaining three stamps were used.

It is believed that most, if not all, of the medio real stamps were sent to sub-offices. They are all from the first period consignment, without invoice number, and in the scarce brown shade. A few of these are known without the Chalco name, used in Xonacatepec.

Due to the above mentioned facts, it should be clear that catalog prices for Chalco Eagles must apply to the ones used in Cuautla de Morelos, while those used in Chalco itself are much scarcer and therefore should command higher prices. Stamps with sub-consignment numbers are the rule in the Chalco district, not the exception as it is in most other districts.

Only four 8R stamps were sent, and none are known to exist today.

Chalco began overprinting its name sometime after the first consignment. Sub-consignment numbers applied in the first period were in a style similar to the ones used for regular overprints in the second period. It is therefore possible to mistake a first period sub-consignment overprint for a second period consignment overprint. The numbers of the sub-consignments in question are: 17-1864, 21-1864, 23-1864, 24-1864, 25-1864, 26-1864, 1-1865 and 2-1865. These were all sub-consignments of first period stamps.

Some sub-offices were so small, and therefore recieved so few stamps, that it is unlikely that any have survived.
