Finding a ZIP+4 in Laredo

Knowing which of these 6 ZIP codes covers an address only gets you partway. The four-digit extension identifies the specific delivery point — typically one side of one block. Two houses facing each other on the same Laredo street almost always have different ZIP+4 codes even though they share all five leading digits.
