One compromise between the large 5 digit zips and the 9-digit zip+4's
is carrier route. There are about 600,000 carrier routes in the USA
each denoted by the 5-digit zip and the carrier route, for example
34685-R036. 600,000 is certainly more manageable than 70,000,000
zip+4's. Does anyone know where you can buy USA carrier route lat/lng
data?

This one also says it's only updated every 6 months. Ouch!! Another
reason I recommend Zipwise instead. Cheaper and fresher data:
