The parcel post and money order services have largely increased since 1887--1888, the number of parcels having almost doubled (those for abroad are more than trebled), while the number of money orders issued is trebled and their value doubled (about 40,000,000).
National and international money order systems are also in operation.
Here are the central offices of the letter, newspaper and telegraph departments, with the office of the Postmaster General; but the headquarters of the parcels department are at Mount Pleasant, Clerkenwell; those of the Post Office Savings Bank at Blythe Road, West Kensington, and those of the Money Order department in Queen Victoria Street.
Peru belongs to the international postal union, and had in 1906 a money order and parcels exchange with seven foreign states.
In connexion with the post-office there are inland money order and savings-bank businesses; and in addition the value-payable system, by which the post-office undertakes to recover from the addressee the value of an article sent by post and to remit the amount to the sender, has found great popularity.
