Talk:Postal codes in Puerto Rico

Untitled
I have not seen anywhere a mention of the USPS changing the format of Puerto Rican addresses. They do all currently have ZIP+4 codes like mainland addresses, and many are similar to mainland ones, as in "123 Xyz Ave". However, many different address formats are documented by the USPS here and here, and I've seen nothing to indicate that these addresses are being changed. Does anyone have a reliable source that would confirm this? –Joonas, 91.153.209.206 (talk) 18:18, 30 January 2010 (UTC)
