From January 1, 2026, Correos will apply a 7.87% increase in the price of national stamps and a 5.49% increase in the price of packages weighing less than one kilo. This tariff revision for 2026, which concerns both ordinary and certified letters as well as international shipments, has already been validated by the National Markets and Competition Commission (CNMC) after determining that it complies with the legal regulations in force.
Although these increases exceed the 3% year-on-year inflation recorded in November, the regulator highlights that prices in Spain continue to be among the most competitive in Europe, being below the average of 1.23 euros adjusted for purchasing power parity.
In the domestic market, postage of an ordinary letter weighing less than 20 grams will cost 0.96 euros, which represents an increase of 7 cents compared to the previous year. This adjustment continues an upward trend that began in 2015, when the stamp cost 0.42 euros, with annual increases ranging between 4% and 11% since then. On the other hand, the national certified letter up to 20 grams will be set at 5.74 euros (8.51% more), while large volume parcels – greater than 20 kilos – will reach a rate of 48.11 euros.
The tariff update has detailed impact internationally, including shipments to Europe and Greenland. The ordinary international letter up to 20 grams will cost 2 euros, while the certified type will cost 7.15 euros. It is important to note that these international rates apply to the European zone, but the operator has expressly excluded from this group countries such as Albania, Armenia, Bosnia, Cyprus, Georgia, Malta, Moldova and Russia, which are governed by different rates.
As for international parcels weighing less than 5 kilos, the price will rise to 50.7 euros (7.42% more) for a large group of strategic destinations. This breakdown includes the continent’s major economic powers such as Germany, France, the United Kingdom, Italy, the Netherlands and Portugal, as well as other markets such as Austria, Belgium, Denmark, Greece, Ireland, Luxembourg, Norway, Sweden and Switzerland. The measure also concerns territories with special regimes or small states, such as Monaco, San Marino, Vatican City, Gibraltar, the Bay of Guernsey and the island of Jersey, in addition to including Ukraine in this tariff group.
At the same time, the CNMC announced that it would intensify monitoring of the special rates that the public operator offers to large companies and administrations. To do this, the Long-Term Incremental Cost (LRIC) standard will be integrated, a measure that takes into account changes in demand.
This system, added to the reporting of historical distributed costs, will allow the regulator to more strictly control that the discounts applied to large business customers strictly adjust to the operating costs of the service in order to avoid distortions in the postal market.
