Stamps to send letters from Spain can be bought from an "estanco" (tobacconist) where you can also buy phone cards. Letters can be posted in the yellow mailboxes found in in the street and at stations and airports. If you want to send a package, wire a money order or send a telegram, you must go to a post office. The post offices also offer fax and certified fax services. Most hotels also have facilities for sending faxes. Post Office website: www.correos.es
To call Spain from abroad, dial +34 (country code for Spain), and then the nine digit phone number. If you want to call from Spain to another country, you must dial 00, followed by the country code and phone number. Calls can be made from public telephones. These operate with coins or phone cards, which can be purchased at tobacconists. For calls within Spain you simply dial the number without any prefixes. This is always a nine digit number, whether for a land line or mobile telephone. If you want to use your mobile in Spain, remember that coverage is based on GSM technology, which is not compatible with phones from some countries such as the United States or Japan. In this case you need a triband mobile. You should contact the operator in the country of origin to ensure that your phone can be used in Spain and for them to activate the international roaming service..
