We Got Mail!!!

I wonder how it would be without a street name or street #? Any idea as to how long the mail took to get to Zihua from the sender?

The trick to getting mail delivered is being on a mail route. If you live in what was until relatively recently a colonia irregular then you will be reminded of the lack of planning that went into the creation of that colonia by the fact that no mail route exists or is planned in the near future. Which means you either get an APDO (apartado) or receive it via Entrega General at the Oficina de Correos.
