Correos is the State-owned provider of postal services in Spain.
Post boxes (buzones) in Spain are bright yellow and are usually free standing. In cities, post boxes may have two slots, one for international mail (extranjero o internacional) and another one for national mail (resto España).
You can find the closest Correos post office or the mailbox on the following Post Office Locator
In addition to the usual post office services, a limited range of other services are provided including telegrams, fax, online documents (burofax), which allows urgent mailing with recorded delivery.
You can also find telex transmissions and domestic and international giro money orders services.
The post office also operates a savings bank (Caja Postal), which may be located in a separate building to a post office.
If you want your mail to be redirected (reexpedir) by the post office, you must visit your closest post office with your name and your old and new addresses. This service redirects national and international mail up to 6 months, depending on your subscription.
