Since 1969, with creation of ECT, the postal system has gained agility and efficiency. Among the measures adopted to modernize the company, are outstanding: creation of postal address code – CEP (zip code), implantation of automatic sorting centers, installation of night air postal network and company computerization.
CEP (Zip code)
In 1971 the postal address code – CEP (zip code) was launched. The five digits standard improves postal services quality.
In 1992 the code has gained three digits, united to the five first by a hyphen. The change, which has facilitated correspondence sorting and postmen job, has also allowed that large buildings, shopping centers, special promotions and large users had an exclusive zip code.
The first digit represents the region (state, part of state or group of states); the second, the sub-region (state capital, state or cities); the third, the sector (states, large cities and a group of middle size cities); the fourth, the sub-sector (middle size cities and group of localities and main venues). The three last digits allow the identification of venues, Correios units, large users, community mailboxes, and promotional events.
In 2000, Correios have launched the national address directory (DNE), a database updated by the CEP (zip code) to be used by companies. A special font for CEPnet follows DNE base, which is CEP in barcode.
In 2012 Correios have innovated DNE and launched e-DNE which started to be bought in few minutes at Internet, in Correios virtual shop, by download. Today your purchase does not need contract formalization; it is made by means of adherence to the Commitment Letter.
Today e-DNE contains over 900 thousand zip codes.
Night postal network
One of most significant Correios advances in the last decades, the night postal network (RPN) is responsible for the daily transportation of over 600 tons of postal objects in Brazil.
A previously unimagined advance for railway postal street vendors from the 19th century who transported postal mails between Rio de Janeiro and São Paulo and were replaced, during the 60s, by road and air transportations.
In the beginning, the forwarding of postal objects was carried out by National air post office (created in 1941 by the merger of military and naval post offices); afterwards, in regular passenger flights holds, when there were few available hours scheduled and space limit in face of the amount of postal cargo to be delivered.
The creation of the night postal air network, in the 70s, came together with a deep restructuring of objects forwarding plan, required for the company to fulfill the D+1 (term that warrants object delivery in the day following postage), adopted at the time in all relevant capitals and cities.
The constant increase in postal traffic volume required and increase in labor force and in physical space for objects handling, which would significantly raise the company operating costs, thus making unfeasible the postal business.
The letters, orders and delivery pouches sorting mechanization was the effective response to win this challenge and promote ECT sustainable development.
Although the first steps in sorting mechanization process have occurred in 1934, with the use of the sorting machine called Transorma, only in 1976 has ECT acquired the first systems for letters and orders processing, imported from Japan and installed in Brasília, Rio de Janeiro and São Paulo.
At the same time, Cargo internal handling mechanized systems were developed and implanted by national companies, which have made handled traffic flow more agile.
Today there are 75 sorting systems in operation in the main Brazilian urban centers and around 75% of postal traffic passes through automatized processes.
CorreiosNet arises in 1997, one of the largest data corporate network in Latin America, comprehending over 6,800 points and interconnecting all company agencies and operation units – in real time – in all country municipalities.
Under a set of high performance computers and around 140 terabytes in data storage area in two Data Centers (Brasília and São Paulo), approximately 1.8 million daily transactions in Postal bank and 900 thousand postal services via service network automation system (SARA).
In 2008, ECT has invested R$ 27 million in the acquisition of last generation equipment to modernize its technological park and support the growth expected for the next years.
By means of mutual cooperation policies and partnerships with government bodies, like Federal Police, Federal Revenue, Anvisa and Ibama, Correios develop continuous action to fight against drugs traffic, illegal commerce, medication and wild animals’ traffic.
In these activities, X-ray equipment and mass spectrometers are used. The equipment operation is performed exclusively by trained employees.
With this work, ECT warrants safety to employees and clients.
Correios Internet portal (www.correios.com.br), created in 1997, receives an average of 25 million visits monthly, outstanding as the third public post office website most visited worldwide, behind United States and England post offices only.
