About Correos

Correos is the national postal operator of Spain, and the thing detected on a website is not the carrier but its shipping integration. Rate lookup at checkout, label generation for the merchant, parcel tracking for the buyer: the code lives inside an existing store, usually as a module for Magento, WooCommerce or PrestaShop, rather than as the store itself.

A fingerprint like Correos therefore answers a commercial question before a technical one. Nobody wires a postal carrier into checkout for engineering reasons. A merchant does it because enough parcels move to Spanish addresses to make manual labelling painful, which means the shop has real order volume and a real domestic customer base. As of October 2026 we see the integration on 3,798 sites, and the resulting population reads as a list of active Spanish market retailers far more than it reads as a list of carrier customers.

Two audiences care about a list like that. Logistics and fulfilment companies use it as a competitive map, because a store that has already integrated one carrier has demonstrated both the need and the technical capacity to integrate another. Ecommerce vendors, payment providers and agencies use it as a qualification filter, since a carrier module implies physical goods, a working checkout, and a shipping cost problem somebody is willing to pay to solve.

Detection has honest limits here. The operator is Correos and the integration is Proprietary, shipped as modules and plugins maintained partly by the carrier and partly by third parties, so what we recognise is the public trace a given module leaves in page markup or in checkout assets. A shop that calls the carrier only from a back office, or that generates labels through a fulfilment partner, ships with Correos while showing nothing to a crawler. Undercounting is the expected direction of the error, and the count should be read as a floor.

A per domain lookup tells you whether one shop offers Correos delivery. The downloadable list answers a different question: which shops across the Spanish market do, what else runs alongside the integration on those domains, and how the set changes between refreshes. Checking a carrier integration one domain at a time is possible. Building a segment out of it is not, unless the whole set arrives at once.
