Download websites that use NACEX

A parcel carrier is not a web technology in any ordinary sense, which is one reason the index files NACEX under Shipping carriers rather than under a tidy engineering label. What a crawler actually finds is a fragment of a checkout: a shipping module, a rate lookup, a tracking panel wired into an order status page. The tag marks a commercial decision that later had to be expressed in code. Someone at the shop signed a carrier contract, and the contract then showed up in the software that takes orders.

The carrier is old by web standards, with 1995 on record as its starting point, and the integration code around it is Proprietary, handed to merchants as modules and plugins rather than published in an open repository. Merchants almost never write that integration themselves. The code arrives as an extension for whichever store platform they already run, which is why the fingerprint looks nearly identical across shops that otherwise have nothing in common.

Geography is doing quiet work in this entry too. The vendor's own site sits under Spain's national domain, and a carrier built around one regional network behaves differently in a dataset than a global logistics integrator does. Its footprint is concentrated by design, so the domains carrying the tag are, in practice, a slice of one market's online retail rather than a scattering across the whole web.

As of October 2026 we record the tag on 155 sites, and the figure deserves a caveat. Detection depends on the integration leaving something visible in the delivered page, so a shop that calls the carrier only from a back office, or that prints labels through desktop software, is invisible to us. The count is a floor on the front-end footprint and not a customer list.

For a competing carrier, a logistics platform, or an agency that builds stores for a living, the useful question is not whether one particular shop offers this delivery option. A per-domain lookup answers that in seconds and for nothing. The question a downloadable list answers is the shape of the population: which store platforms the integration clusters on, which payment and marketing tools sit beside it in the same checkout, and how that set moves between one export and the next. Carrier choice is sticky and rarely reopened, so churn in the list is worth more than its size. A shop that changes platform is a shop whose shipping contract is briefly in play, and the export is where that moment becomes visible.
