If you're looking for local carriers for Mexico, there are a couple of options available if you're after integration with your Shopify Store.
1. Each Shopify Store can directly integrate with UPS and FedEx. This integration allows you to pull their shipping rates, as well as print their shipping labels, within the Shopify Admin. This, however, does require an upgrade to your plan. We also have further information on this feature HERE.
2. There is an app available in our App Store which allows you to connect to different mailing services in Mexico. Based on the app's description, I believe this will be a good option! You can find that HERE.
Take care, Josue ?
Both UPS and FedEx provide local Shipping. UPS has the service UPS Express saver for shipping within Mexico :
You can utilise both these services using the Multi Carrier Shipping label app to show real time shipping rates at checkout and generate labels.
